Market Commentary (Largest price movements within each sector)
 
Sector/Market
Ag/Softs
Grains prices rose on supply concerns stemming from poor weather conditions in South America.  Sugar markets moved lower on the belief that the recent increase in sugar prices would hinder future demand.  In the livestock markets, live cattle prices rose on speculation recent declines in the U.S. dollar would aid meat exports.
Currencies
The U.S. dollar weakened against counterparts as strong housing, employment, and business activity data caused investors to invest in higher-yielding currencies outside the U.S.  Elevated risk-appetite among investors benefitted the Australian and New Zealand dollars, which rose in excess of 2% and 4%, respectively.  The Swiss franc also strengthened against counterparts, driven higher by investors attempting to hedge euro-based positions amidst a shaky outlook for the Eurozone economy.
Energy
Natural gas markets moved sharply higher because of forecasts for abnormally cold weather in the U.S.  Expectations that U.S. natural gas inventories would decline in 2011 also played a role in moving prices higher.
Equities
Japanese equity markets generally declined on the belief a stronger Japanese yen would weaken forecasts for the Japanese export sector.  European equity prices fell because of ongoing uncertainty among investors regarding the financial stability of smaller European nations.
Fixed Income
U.S. Treasury markets rallied as declines in the global equity markets and better-than-expected results from recent Treasury auctions fostered demand.  German bunds also advanced following reports that French third-quarter GDP data was revised lower.
Metals
Precious metals markets moved higher as a U.S. dollar weakness fostered demand.  In the base metals markets, copper prices rallied after the release of reports showed a decline in Chinese copper stockpiles. Copper’s rally was further supported by supply concerns stemming from a production disruption at one of Chile’s key copper mines.

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.
