Partnership's Prospectus dated
June 24, 1988 I

Annual Report to Dean Witter
Multi-Market Portfolio L.P.
Limited Partners for the year
ended December 31, 2000 II, III and IV




































PART I

Item 1. BUSINESS

(a) General Development of Business. Dean Witter Multi-Market

Portfolio L.P. (formerly, Dean Witter Principal Guaranteed Fund

L.P.) (the "Partnership") is a Delaware limited partnership

organized to engage primarily in the speculative trading of

futures contracts, forward contracts, and other commodity

interests.



The general partner for the Partnership is Demeter Management

Corporation ("Demeter"). The non-clearing commodity broker is

Dean Witter Reynolds Inc. ("DWR"). The clearing commodity

brokers are Morgan Stanley & Co. Inc. ("MS & Co.") and Morgan

Stanley & Co. International Limited ("MSIL") which provide

clearing and execution services. Prior to May 2000, Carr Futures

Inc. provided clearing and execution services to the Partnership.

The Trading Advisor is Dean Witter Futures & Currency Management

Inc. ("DWFCM" or the "Trading Advisor"). Demeter, DWR, MS & Co.,

MSIL and DWFCM are wholly-owned subsidiaries of Morgan Stanley

Dean Witter & Co. ("MSDW").



The Partnership's net asset value per unit of limited partnership

interest ("Unit(s)") as of December 31, 2000 was $1,338.12,

representing a gain of 21.6 percent from the net asset value per

Unit of $1,100.09 at December 31, 1999. For a more detailed

description of the Partnership's business see subparagraph (c).



(b) Financial Information about Segments. For financial

information reporting purposes, the Partnership is deemed to

engage in one industry segment, the speculative trading of

futures and forwards. The relevant financial information is

presented in Items 6 and 8.



(c) Narrative Description of Business. The Partnership is in the

business of speculative trading of futures and forwards, pursuant

to trading instructions provided by the Trading Advisor. For a

detailed description of the different facets of the Partnership's

business, see those portions of the Partnership's prospectus (the

"Prospectus"), dated June 24, 1988, incorporated by reference in

this Form 10-K, set forth below:

(d) Financial Information about Geographic Areas.

The Partnership has not engaged in any operations in foreign

countries; however, the Partnership (through the commodity

brokers) enters into forward contract transactions where foreign

banks are the contracting party and trades in futures and

forwards on foreign exchanges.



Item 2. PROPERTIES

The executive and administrative offices are located within the

offices of DWR. The DWR offices utilized by the Partnership are

located at Two World Trade Center, 62nd Floor, New York, NY

10048.



Item 3. LEGAL PROCEEDINGS

Similar class actions were filed in 1996 in California and New





York State courts. Each of these actions were dismissed in 1999.

However, the New York State class action discussed below is still

pending because plaintiffs appealed the trial court's dismissal

of their case on March 3, 2000.



On September 18 and 20, 1996, purported class actions were filed

in the Supreme Court of the State of New York, New York County,

on behalf of all purchasers of interests in limited partnership

commodity pools sold by DWR. Named defendants include DWR,

Demeter, MSDW, DWFCM, certain limited partnership commodity pools

of which Demeter is the general partner and certain trading

advisors to those pools. A consolidated and amended complaint in

the action pending in the Supreme Court of the State of New York

was filed on August 13, 1997, alleging that the defendants

committed fraud, breach of fiduciary duty, and negligent

misrepresentation in the sale and operation of the various

limited partnership commodity pools. The complaints sought

unspecified amounts of compensatory and punitive damages and

other relief. The New York Supreme Court dismissed the New York

action in November 1998, but granted plaintiffs leave to file an

amended complaint, which they did in early December 1998. The

defendants filed a motion to dismiss the amended complaint with

prejudice on February 1, 1999. By decision dated December 21,

1999, the New York Supreme Court dismissed the case with

prejudice. However, on March 3, 2000, plaintiffs appealed the

trial court's dismissal of their case.



Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

None.

















































PART II

Item 5. MARKET FOR THE REGISTRANT'S PARTNERSHIP UNITS AND
RELATED SECURITY HOLDER MATTERS



(a) Market Information

There is no established public trading market for Units of the

Partnership.



(b) Holders

The number of holders of Units at December 31, 2000 was

approximately 1,115.



(c) Distributions

No distributions have been made by the Partnership since it

commenced trading operations on August 31, 1988. Demeter has

sole discretion to decide what distributions, if any, shall be

made to investors in the Partnership. Demeter currently does not

intend to make any distribution of Partnership profits.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Liquidity - The Partnership deposits its assets with DWR as non-

clearing broker and MS & Co. and MSIL as clearing brokers in

separate futures and forwards trading accounts established for

the Trading Advisor, which assets are used as margin to engage in

trading. The assets are held in either non-interest-bearing bank

accounts or in securities and instruments permitted by the

Commodity Futures Trading Commission ("CFTC") for investment of

customer segregated or secured funds. The Partnership's assets

held by the commodity brokers may be used as margin solely for

the Partnership's trading. Since the Partnership's sole purpose

is to trade in futures and forwards, it is expected that the

Partnership will continue to own such liquid assets for margin

purposes.



The Partnership's investment in futures and forwards may, from

time to time, be illiquid. Most U.S. futures exchanges limit

fluctuations in prices during a single day by regulations

referred to as "daily price fluctuations limits" or "daily

limits". Trades may not be executed at prices beyond the daily

limit. If the price for a particular futures contract has

increased or decreased by an amount equal to the daily limit,

positions in that futures contract can neither be taken nor

liquidated unless traders are willing to effect trades at or

within the limit. Futures prices have occasionally moved the

daily limit for several consecutive





days with little or no trading. These market conditions could

prevent the Partnership from promptly liquidating its futures

contracts and result in restrictions on redemptions.



There is no limitation on daily price moves in trading forward

contracts on foreign currencies. The markets for some world

currencies have low trading volume and are illiquid, which may

prevent the Partnership from trading in potentially profitable

markets or prevent the Partnership from promptly liquidating

unfavorable positions in such markets and subjecting it to

substantial losses. Either of these market conditions could

result in restrictions on redemptions.



The Partnership has never had illiquidity affect a material

portion of its assets.



Capital Resources. The Partnership does not have, or expect to

have, any capital assets. Redemptions of Units in the future

will affect the amount of funds available for investments in

futures and forwards in subsequent periods. It is not possible

to estimate the amount and therefore the impact of future

redemptions of Units.





Results of Operations.

General. The Partnership's results depend on its Trading Advisor

and the ability of the Trading Advisor's trading programs to take

advantage of price movements or other profit opportunities in the

futures and forwards markets. The following presents a summary

of the Partnership's operations for the three years ended

December 31, 2000 and a general discussion of its trading

activities during each period. It is important to note, however,

that the Trading Advisor trades in various markets at different

times and that prior activity in a particular market does not

mean that such market will be actively traded by the Trading

Advisor or will be profitable in the future. Consequently, the

results of operations of the Partnership are difficult to discuss

other than in the context of its Trading Advisor's trading

activities on behalf of the Partnership as a whole and how the

Partnership has performed in the past.




At December 31, 2000, the Partnership's total capital was

$8,336,668, an increase of $434,919 from the Partnership's total

capital of $7,901,749 at December 31, 1999. For the year ended

December 31, 2000, the Partnership generated net income of

$1,518,713 and total redemptions aggregated $1,083,794.







For the year ended December 31, 2000, the Partnership recorded

total trading revenues, including interest income, of $2,211,592

and posted an increase in net asset value. In the energy sector,

profits of approximately 18.2% resulted primarily from long

positions in the natural gas and crude oil futures markets.

Natural gas saw its price rise to record levels in 2000. Recent

low inventory levels, sluggish supply and cold winter weather

combined to push prices to such high levels. In the crude oil

market, gains were realized from long positions earlier in the

year as prices rose to nine-year highs on a combination of cold

weather, declining inventories and increasing demand. In

addition, concerns about future output levels from the world's

leading producer countries added to the upward price momentum.

Later in the year, however, profits resulted from short positions

as the price of crude oil futures fell on expectations that Iraqi

oil exports would resume and on fears that the slowdown in the

economy would curb demand while at the same time increase supply.

In the currency markets, gains of approximately 14.2% were

recorded primarily from short positions in the euro, Swiss franc

and Swedish krona as the value of these European currencies

weakened relative to the U.S. dollar amid skepticism about

Europe's economic outlook. Strong economic data out of the U.S.

and interest rate hikes in the U.S. also boosted the dollar and,

subsequently, added to the euro's difficulties. Later in the



year as the bullish trend in the U.S. dollar reversed, additional

gains were recorded from long positions in the euro, Swiss franc

and Swedish krona versus the U.S. dollar as a result of new

confidence in the European economy and overall skepticism

regarding the U.S. economy. Profits of approximately 1.9% were

recorded in the agricultural markets primarily from short

positions in the corn market during the middle of the year as the

price of corn trended lower on favorable weather conditions that

resulted in good prospects for high crop yields. A portion of

these gains was offset by losses experienced in the metals, stock

index and soft commodities markets. The majority of losses,

approximately 7.2%, were experienced in the metals markets

primarily from aluminum futures. From a technical standpoint,

the price of aluminum traded in a very volatile pattern

throughout the year leaving little opportunity for the

development of trends. In addition, long positions in this

market, particularly in the second half of the year, resulted in

losses as prices declined after concerns mounted that demand

would weaken amid a cooling of the U.S. economy. Losses of

approximately 5.1% were recorded in the global stock index

futures markets. The S&P 500 Index traded in a very choppy

pattern resulting in losses for both long and short positions.

Contributing to this price pattern was uncertainty over the state

of the U.S. economy. Total expenses for the year were



$692,879, resulting in net income of $1,518,713. The net asset

value of a Unit increased from 1,100.09 at December 31, 1999 to

1,338.12 at December 31, 2000.



At December 31, 1999, the Partnership's total capital was

$7,901,749, a decrease of $2,070,371 from the Partnership's total

capital of $9,972,120 at December 31, 1998. For the year ended

December 31, 1999, the Partnership generated a net loss of

$848,874 and total redemptions aggregated $1,221,497.



For the year ended December 31, 1999, the Partnership recorded

total trading losses, net of interest income, of $52,906 and

posted a decrease in net asset value per Unit. The Partnership

experienced losses in the global interest rate futures markets of

approximately 8.93%, primarily from short Australian interest

rate futures positions as prices increased during July and August

on the temporary strength in U.S. bonds and weaker-than-expected

business spending data out of Australia. Additional losses were

recorded from short Japanese bond futures positions as prices

increased during the first and third quarters. In the currency

markets, losses of approximately 6.92% were recorded primarily

from Australian dollar positions. Throughout a majority of the

first quarter, losses were experienced from long Australian

dollar positions as its value dropped significantly relative to



the U.S. dollar on speculation regarding potential currency

devaluations in the Asian region. Early in the third quarter,

additional losses were recorded from long positions in this

currency due to depressed commodities prices, emerging market

concerns and on-going talks that China may eventually devalue its

currency. Newly established short positions in the Australian

dollar resulted in losses during September as its value

strengthened relative to the U.S. dollar following the rally in

gold prices. Offsetting currency gains of 3.82% were recorded

from Japanese yen positions, primarily long positions. During

the third quarter, gains were recorded from long positions in the

Japanese yen as the value of the yen climbed to a 44-month high

versus the U.S. dollar due to continued optimism over Japan's

economic recovery. The energy markets produced gains of

approximately 7.21%. During March, gains were recorded from long

positions in oil futures as prices moved significantly higher on

news that both OPEC and non-OPEC countries had reached an

agreement to cut total output beginning April 1st. Gains were

also recorded in this market complex during the third quarter

after OPEC ministers confirmed that they would uphold their

global cutbacks until April of 2000. Total expenses for the year

were $795,968, resulting in a net loss of $848,874. The net

asset value of a Unit decreased from $1,205.86 at December 31,

1998 to $1,100.09 at December 31, 1999.



At December 31, 1998, the Partnership's total capital was

$9,972,120, a decrease of $828,723 from the Partnership's total

capital of $10,800,843 at December 31, 1997. For the year ended

December 31, 1998, the Partnership generated net income of

$540,864 and total redemptions aggregated $1,369,587.



For the year ended December 31, 1998, the Partnership recorded

total trading revenues, including interest income, of $1,454,762

and posted an increase in net asset value per Unit. Gains of

approximately 13.35% were recorded in the global interest rate

futures markets from bond futures in most major world countries

throughout the year. The most significant gains were recorded in

German bond futures, (approximately 5.34%), U.S. bond futures,

(approximately 4.15%) and Japanese bond futures, (approximately

2.85%) from primarily long positions during August and September

as investors sought the safety of fixed income investments from

notable volatility in the global financial markets. Additional

profits were recorded from short Japanese government bond futures

positions during December as prices declined amid a surge in

Japanese bond yields, which was attributed to news that Japan's

Ministry of Finance would end outright purchases of government

debt. Total expenses for the year were $913,898, resulting in

net income of $540,864. The net asset value of a Unit increased





from $1,141.63 at December 31, 1997 to $1,205.86 at December 31,

1998.



The Partnership's overall performance record represents varied

results of trading in different futures and forwards markets.

For a further description of 2000 trading results, refer to the

letter to the Limited Partners in the accompanying Annual Report

to Limited Partners for the year ended December 31, 2000, which

is incorporated by reference to Exhibit 13.01 of this Form 10-K.

The Partnership's gains and losses are allocated among its

partners for income tax purposes.



Credit Risk.

Financial Instruments. The Partnership is a party to financial

instruments with elements of off-balance sheet market and credit

risk. The Partnership may trade futures and forwards in a

portfolio of agricultural commodities, energy products, foreign

currencies, interest rates, precious and base metals, soft

commodities, and stock indices. In entering into these contracts,

the Partnership is subject to the market risk that such contracts

may be significantly influenced by market conditions, such as

interest rate volatility, resulting in such contracts being less

valuable. If the markets should move against all of the

positions held by the Partnership at the same time, and if the



Trading Advisor was unable to offset positions of the

Partnership, the Partnership could lose all of its assets and

investors would realize a 100% loss.



In addition to the Trading Advisor's internal controls, the

Trading Advisor must comply with the trading policies of the

Partnership. These trading policies include standards for

liquidity and leverage with which the Partnership must comply.

The Trading Advisor and Demeter monitor the Partnership's trading

activities to ensure compliance with the trading policies.

Demeter may require the Trading Advisor to modify positions of

the Partnership if Demeter believes they violate the

Partnership's trading policies.



In addition to market risk, in entering into futures and forwards

contracts there is a credit risk to the Partnership that the

counterparty on a contract will not be able to meet its

obligations to the Partnership. The ultimate counterparty or

guarantor of the Partnership for futures contracts traded in the

United States and the foreign exchanges on which the Partnership

trades is the clearinghouse associated with such exchange. In

general, a clearinghouse is backed by the membership of the

exchange and will act in the event of non-performance by one of

its members or one of its member's customers, which should



significantly reduce this credit risk. For example, a

clearinghouse may cover a default by drawing upon a defaulting

member's mandatory contributions and/or non-defaulting members'

contributions to a clearinghouse guarantee fund, established

lines or letters of credit with banks, and/or the clearinghouse's

surplus capital and other available assets of the exchange and

clearinghouse, or assessing its members. In cases where the

Partnership trades off-exchange forward contracts with a

counterparty, the sole recourse of the Partnership will be the

forward contracts counterparty.



There is no assurance that a clearinghouse or exchange will meet

its obligations to the Partnership, and Demeter and the commodity

brokers will not indemnify the Partnership against a default by

such parties. Further, the law is unclear as to whether a

commodity broker has any obligation to protect its customers from

loss in the event of an exchange or clearinghouse defaulting on

trades effected for the broker's customers. Any such obligation

on the part of a broker appears even less clear where the default

occurs in a non-U.S. jurisdiction.



Demeter deals with these credit risks of the Partnership in

several ways. First, it monitors the Partnership's credit

exposure to each exchange on a daily basis, calculating not only



the amount of margin required for it but also the amount of its

unrealized gains at each exchange, if any. The commodity brokers

inform the Partnership, as with all their customers, of its net

margin requirements for all its existing open positions, but do

not break that net figure down, exchange by exchange. Demeter,

however, has installed a system which permits it to monitor the

Partnership's potential margin liability, exchange by exchange.

As a result, Demeter is able to monitor the Partnership's

potential net credit exposure to each exchange by adding the

unrealized trading gains on that exchange, if any, to the

Partnership's margin liability thereon.



Second, the Partnership's trading policies limit the amount of

its net assets that can be committed at any given time to futures

contracts and require, in addition, a minimum amount of

diversification in the Partnership's trading, usually over

several different products. One of the aims of such trading

policies has been to reduce the credit exposure of the

Partnership to a single exchange and, historically, the

Partnership's exposure to any one exchange has typically amounted

to only a small percentage of its total net assets. On those

relatively few occasions where the Partnership's credit exposure

may climb above such level, Demeter deals with the situation on a

case by case basis, carefully weighing whether the increased



level of credit exposure remains appropriate. Material changes

to the trading policies may be made only with the prior written

approval of the Limited Partners owning more than 50% of Units

then outstanding.



Third, with respect to forward contract trading, the Partnership

trades with only those counterparties which Demeter, together

with DWR, have determined to be creditworthy. The Partnership

presently deals with MS & Co. as the sole counterparty on

forwards contracts.



See "Financial Instruments" under Notes to Financial Statements

in the Partnership's Annual Report to Limited Partners for the

year ended December 31, 2000, which is incorporated by reference

to Exhibit 13.01 of this Form 10-K.


Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
RISK

Introduction

The Partnership is a commodity pool involved in the speculative

trading of futures and forwards. The market-sensitive

instruments held by the Partnership are acquired for speculative

trading purposes only and, as a result, all or substantially all

of the Partnership's assets are at risk of trading loss. Unlike

an





operating company, the risk of market-sensitive instruments is

central, not incidental, to the Partnership's main business

activities.



The futures and forwards traded by the Partnership involve

varying degrees of related market risk. Market risk is often

dependent upon changes in the level or volatility of interest

rates, exchange rates, and prices of financial instruments and

commodities. Fluctuations in market risk based upon these

factors result in frequent changes in the fair value of the

Partnership's open positions, and, consequently, in its earnings

and cash flow.



The Partnership's total market risk is influenced by a wide

variety of factors, including the diversification among the

Partnership's open positions, the volatility present within the

markets, and the liquidity of the markets. At different times,

each of these factors may act to increase or decrease the market

risk associated with the Partnership.



The Partnership's past performance is not necessarily indicative

of its future results. Any attempt to numerically quantify the

Partnership's market risk is limited by the uncertainty of its





speculative trading. The Partnership's speculative trading may

cause future losses and volatility (i.e. "risk of ruin") that far

exceed the Partnership's experiences to date or any reasonable

expectations based upon historical changes in market value.



Quantifying the Partnership's Trading Value at Risk

The following quantitative disclosures regarding the

Partnership's market risk exposures contain "forward-looking

statements" within the meaning of the safe harbor from civil

liability provided for such statements by the Private Securities

Litigation Reform Act of 1995 (set forth in Section 27A of the

Securities Act of 1933 and Section 21E of the Securities Exchange

Act of 1934). All quantitative disclosures in this section are

deemed to be forward-looking statements for purposes of the safe

harbor, except for statements of historical fact.



The Partnership accounts for open positions using mark-to-market

accounting principles. Any loss in the market value of the

Partnership's open positions is directly reflected in the

Partnership's earnings, whether realized or unrealized, and its

cash flow. Profits and losses on open positions of exchange-

traded futures and forwards are settled daily through variation

margin.





The Partnership's risk exposure in the market sectors traded by

the Trading Advisor is estimated below in terms of Value at Risk

("VaR"). The VaR model used by the Partnership includes many

variables that could change the market value of the Partnership's

trading portfolio. The Partnership estimates VaR using a model

based upon historical simulation with a confidence level of 99%.

Historical simulation involves constructing a distribution of

hypothetical daily changes in the value of a trading portfolio.



The VaR model takes into account linear exposures to price and

interest rate risk. Market risks that are incorporated in the

VaR model include equity and commodity prices, interest rates,

foreign exchange rates, and correlation among these variables.

The hypothetical changes in portfolio value are based on daily

percentage changes observed in key market indices or other market

factors ("market risk factors") to which the portfolio is

sensitive. The historical observation period of the

Partnership's VaR is approximately four years. The one-day 99%

confidence level of the Partnership's VaR corresponds to the

negative change in portfolio value that, based on observed market

risk factors, would have been exceeded once in 100 trading days.



VaR models, including the Partnership's, are continuously

evolving as trading portfolios become more diverse and modeling



techniques and systems capabilities improve. Please note that

the VaR model is used to numerically quantify market risk for

historic reporting purposes only and is not utilized by either

Demeter or the Trading Advisor in their daily risk management

activities.


The Partnership's Value at Risk in Different Market Sectors

The following table indicates the VaR associated with the

Partnership's open positions as a percentage of total net assets

by primary market risk category as of December 31, 2000 and 1999.

At both December 31, 2000 and 1999, the Partnership's total

capitalization was approximately $8 million.


Primary Market December 31, 2000 December 31, 1999
Risk Category Value at Risk Value at Risk

Interest Rate (2.82)% (0.22)%

Currency (1.64) (0.79)

Commodity (1.07) (0.81)

Equity (0.25) (0.16)

Aggregate Value at Risk (3.31)% (1.26)%



Aggregate Value at Risk represents the aggregate VaR of all the

Partnership's open positions and not the sum of the VaR of the

individual market categories listed above. Aggregate VaR will be

lower as it takes into account correlation among different

positions and categories.



The table above represents the VaR of the Partnership's open

positions at December 31, 2000 and 1999 only and is not

necessarily representative of either the historic or future risk

of an investment in the Partnership. Because the Partnership's

only business is the speculative trading of futures and forwards,

the composition of its trading portfolio can change significantly

over any given time period, or even within a single trading day.

Any changes in open positions could positively or negatively

materially impact market risk as measured by VaR.



The table below supplements the December 31, 2000 VaR by

presenting the Partnership's high, low and average VaR, as a

percentage of total net assets for the four quarterly reporting

periods from January 1, 2000 through December 31, 2000.



Primary Market Risk Category High Low Average

Interest Rate (2.82)% (0.57)% (1.61)%

Currency (2.74) (1.42) (1.86)

Commodity (2.41) (1.07) (1.79)

Equity (1.16) - (0.37)

Aggregate Value at Risk (3.31)% (2.59)% (3.11)%

Limitations on Value at Risk as an Assessment of Market Risk

The face value of the market sector instruments held by the

Partnership is typically many times the applicable margin



requirements. Margin requirements generally range between 2% and

15% of contract face value. Additionally, the use of leverage

causes the face value of the market sector instruments held by

the Partnership to typically be many times the total

capitalization of the Partnership. The value of the

Partnership's open positions thus creates a "risk of ruin" not

usually found in other investments. The relative size of the

positions held may cause the Partnership to incur losses greatly

in excess of VaR within a short period of time, given the effects

of the leverage employed and market volatility. The VaR tables

above, as well as the past performance of the Partnership, give

no indication of such "risk of ruin". In addition, VaR risk

measures should be viewed in light of the methodology's

limitations, which include the following:

past changes in market risk factors will not always result

in accurate predictions of the distributions and correlations of

future market movements;

changes in portfolio value in response to market movements

may differ from those of the VaR model;

VaR results reflect past trading positions while future risk

depends on future positions;











VaR using a one-day time horizon does not fully capture the

market risk of positions that cannot be liquidated or hedged

within one day; and

the historical market risk factor data used for VaR

estimation may provide only limited insight into losses that

could be incurred under certain unusual market movements.



VaR tables above present the results of the Partnership's VaR for

each of the Partnership's market risk exposures and on an

aggregate basis at December 31, 2000 and 1999, and for the end of

the four quarterly reporting periods during calendar year 2000.

Since VaR is based on historical data, VaR should not be viewed

as predictive of the Partnership's future financial performance

or its ability to manage or monitor risk. There can be no

assurance that the Partnership's actual losses on a particular

day will not exceed the VaR amounts indicated above or that such

losses will not occur more than once in 100 trading days.



Non-Trading Risk

The Partnership has non-trading market risk on its foreign cash

balances not needed for margin. These balances and any market

risk they may represent are immaterial. At December 31, 2000, the

Partnership's cash balance at DWR was approximately 85% of its





total net asset value. A decline in short-term interest rates

will result in a decline in the Partnership's cash management

income. This cash flow risk is not considered to be material.



Materiality, as used throughout this section, is based on an

assessment of reasonably possible market movements and any

associated potential losses taking into account the leverage,

optionality and multiplier features of the Partnership's market-

sensitive instruments.



Qualitative Disclosures Regarding Primary Trading Risk Exposures

The following qualitative disclosures regarding the Partnership's

market risk exposures - except for (A) those disclosures that are

statements of historical fact and (B) the descriptions of how the

Partnership manages its primary market risk exposures -

constitute forward-looking statements within the meaning of

Section 27A of the Securities Act and Section 21E of the

Securities Exchange Act. The Partnership's primary market risk

exposures as well as the strategies used and to be used by

Demeter and the Trading Advisor for managing such exposures are

subject to numerous uncertainties, contingencies and risks, any

one of which could cause the actual results of the Partnership's

risk controls to differ materially from the objectives of such

strategies. Government interventions, defaults and

expropriations, illiquid markets, the emergence of



dominant fundamental factors, political upheavals, changes in

historical price relationships, an influx of new market

participants, increased regulation and many other factors could

result in material losses as well as in material changes to the

risk exposures and the risk management strategies of the

Partnership. Investors must be prepared to lose all or

substantially all of their investment in the Partnership.



The following were the primary trading risk exposures of the

Partnership as of December 31, 2000 by market sector. It may be

anticipated, however, that these market exposures will vary

materially over time.



Interest Rate. The largest market exposure at December 31, 2000

was in the interest rate complex. Exposure was spread across

European, United States, Japanese and Australian interest rate

sectors. Interest rate movements directly affect the price of

the sovereign bond futures positions held by the Partnership and

indirectly affect the value of its stock index and currency

positions. Interest rate movements in one country as well as

relative interest rate movements between countries materially

impact the Partnership's profitability. The Partnership's

primary interest rate exposure is generally to interest rate

fluctuations in the United States and the other G-7 countries.



The G-7 countries consist of France, U.S., Britain, Germany,

Japan, Italy and Canada. However, the Partnership also takes

futures positions in the government debt of smaller nations -

e.g. Australia. Demeter anticipates that G-7 and Australian

interest rates will remain the primary interest rate exposure of

the Partnership for the foreseeable future. The changes which

have the most effect on the Partnership are in short to

intermediate-term as opposed to long-term rates as most of the

speculative interest rate futures positions held by the

Partnership are in short-term and medium-term instruments.



Currency. The next most significant market exposure of the

Partnership at December 31, 2000 was in the foreign exchange

complex. The currency exposure is to exchange rate fluctuations,

primarily those which disrupt the historical pricing

relationships between different currencies and currency pairs.

Interest rate changes as well as political and general economic

conditions influence these fluctuations. The Partnership trades

in a large number of currencies, including cross-rates - i.e.,

positions between two currencies other than the U.S. dollar. The

Partnership's major exposures were in the euro currency crosses

and outright U.S. dollar positions. Outright positions consist

of the U.S. dollar vs. other currencies. These other currencies

include the major and minor currencies. Demeter does not



anticipate that the risk profile of the Partnership's currency

sector will change significantly in the future. The currency

trading VaR figure includes foreign margin amounts converted into

U.S. dollars with an incremental adjustment to reflect the

exchange rate risk inherent to the dollar-based Partnership in

expressing VaR in a functional currency other than U.S. dollars.



Commodity.

Energy. At December 31, 2000 the Partnership's next largest

exposure was in the energy complex. The largest exposure was in

natural gas, followed by crude oil and brent crude. Price

movement in these markets results from political developments in

Middle Eastern and OPEC and non-OPEC oil producing countries.

Weather patterns and other economic fundamentals also affect

prices. It is possible that volatility will remain high and that

significant profits and losses, which have been experienced in

the past, will continue to be experienced in this market.

Natural gas has exhibited volatility in prices resulting from

weather patterns and supply and demand factors and may continue

in this choppy pattern.



Soft Commodities and Agriculturals . At December 31, 2000 the

Partnership had exposure in the markets that comprise these

sectors. Exposure was in the corn, soybean, cotton, cocoa and



coffee markets. Supply and demand inequalities, severe weather

disruption and market expectations affect price movements in

these markets.



Metals. The Partnership's smallest exposure as of the end of the

fourth quarter was in the metals complex. The only positions

were in the LME nickel market. Prices in this market are

influenced by general economic conditions and warehouse stocks.



Equity. There was a relatively small exposure to stock indices

as of December 31, 2000. The Partnership trades these markets in

the United States and Japan and had small positions in both

markets. Stock indexes are affected by the same factors that

influence the underlying equity issues such as the monetary and

fiscal policies of government, profit outlook and general

economic conditions.



Qualitative Disclosures Regarding Non-Trading Risk Exposure

The following was the only non-trading risk exposure of the

Partnership at December 31, 2000:

Foreign Currency Balances. The Partnership's primary

foreign currency balances were in British Pounds. The

Partnership controls the non-trading risk of these balances

by regularly converting these balances back into U.S.

dollars upon liquidation of the respective position.



Qualitative Disclosures Regarding Means of Managing Risk Exposure

The Partnership and the Trading Advisor, separately, attempt to

manage the risk of the Partnership's open positions in

essentially the same manner in all market categories traded.

Demeter attempts to manage market exposure by diversifying the

Partnership's assets among different market sectors and trading

approaches, and monitoring the performance of the Trading Advisor

daily. In addition, the Trading Advisor establishes

diversification guidelines, often set in terms of the maximum

margin to be committed to positions in any one market sector or

market-sensitive instrument.



Demeter monitors and controls the risk of the Partnership's non-

trading instrument, cash. Cash is the only Partnership

investment directed by Demeter, rather than the Trading Advisor.

Dean Witter Multi-Market Portfolio L.P.
Annual Report of the Trading Manager

The Fund posted gains in 2000 as a result of strong trends in the energy, cur-
rency, and grain futures markets. In the energy sector, profits resulted from
long positions in the natural gas and crude oil futures markets. Natural gas
saw its price rise to record levels in 2000. Recent low inventory levels,
sluggish supply and cold winter weather combined to push prices to such high
levels. In the crude oil market, gains were realized from long positions ear-
lier in the year as prices rose to nine-year highs on a combination of cold
weather, declining inventories and increasing demand. In addition, concerns
about future output levels from the world's leading producer countries added
to the upward price momentum. Later in the year, however, profits resulted
from short positions as the price of crude oil futures fell on expectations
that Iraqi oil exports would resume and on fears that the slowdown in the
economy would curb demand while at the same time supply was increasing. In the
currency markets, gains were recorded from short positions in the euro, Swiss
franc and Swedish krona as the value of these European currencies weakened
relative to the U.S. dollar amid skepticism about Europe's economic outlook.
Strong economic data out of the U.S. and interest rate hikes in the U.S. also
boosted the dollar and, subsequently, added to the euro's difficulties. Later
in the year as the bullish trend in the U.S. dollar reversed, additional gains
were recorded from long positions in the euro, Swiss franc and Swedish krona
versus the U.S. dollar as a result of new confidence in the European economy
and an overall skepticism regarding the U.S. economy. Profits were also rec-
orded from short positions in the corn market during the middle of the year as
the price of corn trended lower on favorable weather conditions that resulted
in good prospects for high crop yields.

A portion of these gains was offset by losses experienced in the metals, stock
index and soft commodity futures markets. The majority of losses in the metals
markets were experienced in the aluminum market. From a technical standpoint,
the price of aluminum traded in a very volatile pattern throughout the year
leaving little opportunity for the development of trends. In addition, long
positions in this market, particularly in the second half of the year, result-
ed in losses as price declined after


concerns mounted that demand would weaken amid a cooling of the U.S. economy.
Losses were also recorded in the global stock index futures markets. The S&P
500 Index traded in a very choppy pattern resulting in losses for both long
and short positions. Contributing to this price pattern was uncertainty over
the state of the U.S. economy.

The Limited Partners and the General Partner:

We have audited the accompanying statements of financial condition of Dean
Witter Multi-Market Portfolio L.P. (the "Partnership") as of December 31, 2000
and 1999 and the related statements of operations, changes in partners' capi-
tal, and cash flows for each of the three years in the period ended December
31, 2000. These financial statements are the responsibility of the Partner-
ship's management. Our responsibility is to express an opinion on these finan-
cial statements based on our audits.

We conducted our audits in accordance with auditing standards generally ac-
cepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the finan-
cial statements are free of material misstatement. An audit includes examin-
ing, on a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting princi-
ples used and significant estimates made by management, as well as evaluating
the overall financial statement presentation. We believe that our audits pro-
vide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material re-
spects, the financial position of Dean Witter Multi-Market Portfolio L.P. at
December 31, 2000 and 1999 and the results of its operations and its cash

Dean Witter Multi-Market Portfolio L.P.
Notes to Financial Statements

1. Summary of Significant Accounting Policies

Organization--Dean Witter Multi-Market Portfolio L.P. (the "Partnership") is a
limited partnership organized to engage in the speculative trading of futures
contracts, forward contracts and other commodity interests (collectively,
"futures interests").

The general partner for the Partnership is Demeter Management Corporation
("Demeter"). The non-clearing commodity broker is Dean Witter Reynolds Inc.
("DWR"). Morgan Stanley & Co., Inc. ("MS&Co.") and Morgan Stanley & Co. Inter-
national Limited ("MSIL"), provide clearing and execution services. Prior to
May 2000, Carr Futures Inc. ("Carr") provided clearing and execution services
to the Partnership. The trading advisor is Dean Witter Futures & Currency Man-
agement Inc. ("DWFCM" or the "Trading Advisor"). Demeter, DWR, MS&Co., MSIL
and DWFCM are wholly-owned subsidiaries of Morgan Stanley Dean Witter & Co.
("MSDW").

Effective February 19, 1998, Morgan Stanley, Dean Witter, Discover & Co.
changed its corporate name to Morgan Stanley Dean Witter & Co.

Demeter is required to maintain a 1% minimum interest in the equity of the
Partnership and income (losses) are shared by Demeter and the Limited Partners
based upon their proportional ownership interests.

Use of Estimates--The financial statements are prepared in accordance with ac-
counting principles generally accepted in the United States of America, which
require management to make estimates and assumptions that affect the reported
amounts in the financial statements and related disclosures. Management be-
lieves that the estimates utilized in the preparation of the financial state-
ments are prudent and reasonable. Actual results could differ from those esti-
mates.

Revenue Recognition--Futures interests are open commitments until settlement
date. They are valued at market on a daily basis and the resulting net change
in unrealized gains and losses are reflected in the change in unrealized prof-
it (loss) on open contracts from one period to the next in the statements of
operations. Monthly, DWR pays the Partnership interest income based upon 80%
of the average daily Net Assets for the month at a rate equal to the average
yield on 13-week U.S. Treasury bills. For purposes of such interest payments,
Net Assets do not include monies due the Partnership on futures interests, but
not actually received.

Net Income (Loss) per Unit--Net income (loss) per unit of limited partnership
interest ("Unit(s)") is computed using the weighted average number of Units
outstanding during the period.


Dean Witter Multi-Market Portfolio L.P.
Notes to Financial Statements--(Continued)

Equity in Futures Interests Trading Accounts--The Partnership's asset "Equity
in futures interests trading accounts," reflected in the statements of finan-
cial condition, consists of (A) cash on deposit with DWR, MS&Co. and MSIL to
be used as margin for trading and (B) net unrealized gains or losses on open
contracts which are valued at market, and calculated as the difference between
original contract value and market value.

The Partnership, in the normal course of business, enters into various con-
tracts with MS&Co. and MSIL acting as its commodity brokers. Pursuant to bro-
kerage agreements with MS&Co. and MSIL, to the extent that such trading re-
sults in unrealized gains or losses, the amounts are offset and reported on a
net basis on the Partnership's statements of financial condition.

The Partnership has offset the fair value amounts recognized for forward con-
tracts executed with the same counterparty as allowable under terms of the
master netting agreement with MS&Co., the sole counterparty on such contracts.
The Partnership has consistently applied its right to offset.

Brokerage Commissions and Related Transaction Fees and Costs--Brokerage com-
missions are accrued on a half-turn basis at 80% of DWR's published non-member
rates. Transaction fees and costs are accrued on a half-turn basis. Total bro-
kerage commissions, and transaction fees and costs are capped at 13/20 of 1%
(a 7.8% maximum annual rate) per month of the Partnership's month-end Net As-
sets.

Operating Expenses--The Partnership incurs a monthly management fee and may
incur incentive fees. Demeter and/or DWR bear all other operating expenses.

Redemptions--Limited Partners may redeem some or all of their Units at 100% of
the Net Asset Value per Unit as of the last day of any month upon five busi-
ness days advance notice by redemption form to Demeter.

Distributions--Distributions, other than redemptions of Units, are made on a
pro-rata basis at the sole discretion of Demeter. No distributions have been
made to date.

Income Taxes--No provision for income taxes has been made in the accompanying
financial statements, as partners are individually responsible for reporting
income or loss based upon their respective share of the Partnership's revenues
and expenses for income tax purposes.

Dissolution of the Partnership--The Partnership will terminate on December 31,
2025 or at an earlier date if certain conditions set forth in the Limited
Partnership Agreement occur.


Dean Witter Multi-Market Portfolio L.P.
Notes to Financial Statements--(Continued)

2. Related Party Transactions

The Partnership pays brokerage commissions to DWR as described in Note 1. The
Partnership's cash is on deposit with DWR, MS&Co., and MSIL in futures inter-
ests trading accounts to meet margin requirements as needed. DWR pays interest
on these funds as described in Note 1.

Demeter, on behalf of the Partnership and itself, has entered into a Manage-
ment Agreement with DWFCM to make all trading decisions for the Partnership.

Compensation to DWFCM by the Partnership consists of a management fee and an
incentive fee as follows:

Management Fee--As of the last day of each month, the Partnership pays a
monthly management fee equal to 1/4 of 1% (a 3% annual rate) of the Partner-
ship's adjusted Net Assets, as defined, that are allocated to futures interest
trading accounts which DWFCM trades on behalf of the Partnership.

Incentive Fee--The Partnership will pay a quarterly incentive fee equal to 15%
of the trading profits earned by the Partnership as of the end of each calen-
dar quarter. Trading profits represent the amount by which profits from
futures, forwards and options trading exceed losses after brokerage commis-
sions, management fees and, transaction fees and costs have been deducted. No
incentive fee will be paid until the existing trading loss carryforward (ad-
justed for redemptions) has been recovered.

3. Financial Instruments

The Partnership trades futures contracts, forward contracts and other commodi-
ty interests. Futures and forwards represent contracts for delayed delivery of
an instrument at a specified date and price. Risk arises from changes in the
value of these contracts and the potential inability of counterparties to per-
form under the terms of the contracts. There are numerous factors which may
significantly influence the market value of these contracts, including inter-
est rate volatility.

In June 1998, the Financial Accounting Standards Board ("FASB") issued State-
ment of Financial Accounting Standard ("SFAS") No. 133, "Accounting for Deriv-
ative Instruments and Hedging Activities" effective for fiscal years beginning
after June 15, 2000, as amended by SFAS No. 137. The Partnership adopted the
provisions of SFAS No. 133 beginning with the fiscal year ended December 31,
1998. SFAS No. 133 superceded SFAS Nos. 119 and 105, which required the dis-
closure of average aggregate fair values and contract/notional


Dean Witter Multi-Market Portfolio L.P.
Notes to Financial Statements--(Continued)

values, respectively, of derivative financial instruments for an entity that
carries its assets at fair value. SFAS No. 133 was further amended by SFAS No.
138, which clarifies issues surrounding interest rate risk, foreign currency
denominations, normal purchases and sales and net hedging. The application of
SFAS No. 133, as amended by SFAS No. 137 and SFAS No. 138, did not have a sig-
nificant effect on the Partnership's financial statements.

SFAS No. 133 defines a derivative as a financial instrument or other contract
that has all three of the following characteristics:

(1) One or more underlying notional amounts or payment provisions;
(2) Requires no initial net investment or a smaller initial net investment
than would be required relative to changes in market factors;
(3) Terms require or permit net settlement.

Generally derivatives include futures, forwards, swaps or option contracts, or
other financial instruments with similar characteristics such as caps, floors
and collars.

The net unrealized gains on open contracts are reported as a component of "Eq-
uity in futures interests trading accounts" on the statements of financial
condition and totaled $1,101,850 and $358,067 at December 31, 2000 and 1999,
respectively.

Of the $1,101,850 net unrealized gain on open contracts at December 31, 2000,
$779,384 related to exchange-traded futures contracts and $322,466 related to
off-exchange-traded forward currency contracts.

Of the $358,067 net unrealized gain on open contracts at December 31, 1999,
$327,051 related to exchange-traded futures contracts and $31,016 related to
off-exchange-traded forward currency contracts.

Exchange-traded futures contracts held by the Partnership at December 31, 2000
and 1999 mature through June 2002 and September 2000, respectively. Off-
exchange-traded forward currency contracts held by the Partnership at December
31, 2000 and 1999 mature through March 2001 and March 2000, respectively.

The Partnership has credit risk associated with counterparty nonperformance.
The credit risk associated with the instruments in which the Partnership is
involved is limited to the amounts reflected in the Partnership's statements
of financial condition.


Dean Witter Multi-Market Portfolio L.P.
Notes to Financial Statements--(Continued)

The Partnership also has credit risk because DWR, MS&Co., and MSIL act as the
futures commission merchants or the counterparties with respect to most of the
Partnership's assets. Exchange-traded futures contracts are marked to market
on a daily basis, with variations in value settled on a daily basis. DWR,
MS&Co. and MSIL each as a futures commission merchant for the Partnership's
exchange-traded futures contracts, are required, pursuant to regulations of
the Commodity Futures Trading Commission, to segregate from their own assets,
and for the sole benefit of their commodity customers, all funds held by them
with respect to exchange-traded futures contracts, including an amount equal
to the net unrealized gains on all open futures contracts, which funds, in the
aggregate, totaled $8,118,738 and $7,971,000 at December 31, 2000 and 1999,
respectively. With respect to the Partnership's off-exchange-traded forward
currency contracts, there are no daily settlements of variations in value nor
is there any requirement that an amount equal to the net unrealized gain on
open forward contracts be segregated. With respect to those off-exchange-trad-
ed forward currency contracts, the Partnership is at risk to the ability of
MS&Co., the sole counterparty on all of such contracts, to perform. The Part-
nership has a netting agreement with MS&Co. This agreement, which seeks to re-
duce both the Partnership's and MS&Co.'s exposure on off-exchange-traded for-
ward currency contracts, should materially decrease the Partnership's credit
risk in the event of MS&Co.'s bankruptcy or insolvency.

4. Legal Matters

Similar class actions were filed in 1996 in California and New York State
courts. Each of the actions were dismissed in 1999. However, the New York
State class action discussed below is still pending because plaintiffs ap-
pealed the trial court's dismissal of their case on March 3, 2000.

On September 18 and 20, 1996, purported class actions were filed in the Su-
preme Court of the State of New York, New York County, on behalf of all pur-
chasers of interests in limited partnership commodity pools sold by DWR. Named
defendants include DWR, Demeter, DWFCM, MSDW, certain limited partnership com-
modity pools of which Demeter is the general partner and certain trading ad-
visors to those pools. A consolidated and amended complaint in the action
pending in the Supreme Court of the State of New York was filed on August 13,
1997, alleging that the defendants committed fraud, breach of fiduciary duty,
and negligent misrepresentation in the sale and operation of the various lim-
ited partnership commodity pools. The complaints sought unspecified amounts of
compensatory and punitive damages and other relief. The New York Supreme Court
dismissed the New York action in November


Dean Witter Multi-Market Portfolio L.P.
Notes to Financial Statements--(Concluded)

1998, but granted plaintiffs leave to file an amended complaint, which they
did in early December 1998. The defendants filed a motion to dismiss the
amended complaint with prejudice on February 1, 1999. By decision dated Decem-
ber 21, 1999, the New York Supreme Court dismissed the case with prejudice.
However, on March 3, 2000, plaintiffs appealed the trial court's dismissal of
their case.
