Market Commentary (Largest price movements within each sector)
 
Sector/Market
 
Ags/Softs
Corn and wheat prices rose last week following a government report showing increased export demand for U.S. grains.  Soybean prices also rose, as adverse weather conditions in Argentina resulted in supply concerns. Cocoa prices increased due to speculation about violence in the Ivory Coast and its potential affect on supply chains.
Currencies
The euro weakened following reports that Spain’s credit rating is under review for a potential downgrade.   The U.S. dollar strengthened after the release of several favorable economic reports, including positive manufacturing data for December.  In New Zealand, waning investor confidence led to a sharp decline in the New Zealand dollar.
Energy
Natural gas prices fell last week following forecasts of warmer-than-expected weather in major gas-heating areas around the United States.  Adding to the decline in natural gas was data showing increased natural gas production.
Equities
Japanese equity markets rallied due to a combination of improved investor sentiment in the region and weakness in the Japanese yen. A weaker currency makes Japanese exports more attractive to international investors.  In Hong Kong, the Hang Seng finished the week nearly 2% lower as ongoing fears continued regarding future Chinese monetary policy.
Fixed Income
U.S. Treasury Bonds declined following positive data from the Philadelphia Federal Reserve that showed improved prospects for economic growth.  European debt markets generally fell due to investor uncertainty regarding future economic policy shifts in the E.U. This was a result of the financial instability of some of its smaller member nations.
Metals
Industrial metals rallied last week as a result of China’s recent decision to keep interest rates unchanged.  In the precious metals markets, gold prices fell in the wake of U.S. dollar strength.  Silver markets experienced gains because of heavy buying by large commodity funds attempting to take advantage of recent trends.

Performance Chart
 
Barclays Capital U.S. Long Government Index (formerly Lehman Brothers U.S. Government Index:  Long Subset):  A benchmark comprised of the Barclays Capital U.S. Treasury and U.S. Agency indices.  The U.S. Long Government Index includes Treasuries (public obligations of the U.S. Treasury that have remaining maturities of more than ten years) and U.S. agency debentures (publicly issued debt of U.S. Government agencies, quasi-federal corporations, and corporate or foreign debt guaranteed by the U.S. Government). The U.S. Government Index is a component of the Barclays Capital U.S. Government Index.

Compounded Annualized Rate of Return (ROR): This is the geometric 12-month mean that assumes the same rate of return for each 12-month period to arrive at the equivalent compound growth rate reflected in the actual return data.

Standard and Poor’s 500 Total Return Index (S&P 500 Index): A weighted index of the 500 stocks in the S&P 500 Index, which are chosen by Standard and Poor’s based on industry representation, liquidity, and stability.  The stocks in the S&P 500 Index are not the 500 largest companies; rather the index is designed to capture the returns of many different sectors of the U.S. economy.  The total return calculation includes the price-plus-gross cash dividend return.

Standard Deviation: Measures the dispersal or uncertainty in a random variable (in this case, investment returns). It measures the degree of variation of returns around the mean, or average, return. The higher the volatility of the investment returns, the higher the standard deviation will be. For this reason, standard deviation is often used as a measure of investment risk.


 
Risk Metrics Chart
 
Drawdown: A drawdown is any losing period during an investment’s performance history. It is defined as the percent retrenchment from an equity peak to an equity valley. Maximum drawdown is simply the largest percentage drawdown that has occurred during the specified time frame. Grant Park’s drawdowns are computed based on month-end equity values.

Sharpe Ratio: A return/risk measure defined as the average incremental return of an investment over the risk free rate.

Sortino Ratio: A ratio developed to differentiate between good and bad volatility. The calculation provides a risk-adjusted measure of performance without penalizing for upward price changes.
