Market Commentary (Largest price movements within each sector)

Sector/Market
Energy	Crude oil markets fell over 4% in anticipation of reduced demand by global refiners. The easing of supply concerns surrounding the violence in Iraq and the sanctions on Russia also played a role in driving crude oil prices lower. Natural gas markets finished modestly higher after the U.S. Energy Information Administration reported domestic inventories rose less-than-expected.
Grains/Foods	Corn and wheat prices fell as data continued to support strong output for this year’s harvest. Soybean markets rose modestly higher on strong export and demand data. Coffee prices rallied sharply to multi-month highs because of ongoing concerns surrounding drought-ridden crops in Brazil.
Metals	Precious metals markets declined due to better-than-expected economic data which demonstrated strong U.S. growth and on the belief the U.S. Federal Reserve may soon raise interest rates. Base metals markets also fell, driven lower by high levels of supplies and by disappointing manufacturing data from China.
Currencies	The U.S. dollar generally rose against counterparts as bullish growth data drove global investors towards U.S. assets. The Japanese yen fell sharply due to weak data from the region. The euro was virtually unchanged as bullish investor sentiment data nearly offset an early-week selloff.
Equities	The S&P 500 experienced its biggest weekly decline since 2012 after the release of disappointing U.S. employment data and the news Argentina had defaulted on a sovereign bond payment. Ongoing concerns about the weakness of the Portuguese economy and continued violence in Ukraine and the Middle East also contributed to equity market declines. In Japan, the Nikkei 225 Index rose nearly 1%, supported by strong corporate earnings from Japanese carmakers and in weakness in the yen.
Fixed Income	U.S. Treasury markets experienced mixed results as weakness caused by strong U.S. growth data was offset by Argentina’s debt-default crisis and by a disappointing U.S. employment report. German Bund prices rallied as demand increased as investors attempted to diversify away from the sovereign debt of less-stable Eurozone nations.

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.

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.

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.
