Market Commentary (Largest price movements within each sector)

Sector/Market
Energy	Crude oil prices fell by more than 2% after the U.S. Energy Information Administration announced an increase in overall oil inventories. Heating oil prices lost more than 4% due to an overall decrease in demand, coupled with increased supplies.
Grains/Foods	Cotton prices fell in excess of 4% after the Indian Cotton Federation released data which showed an increase in overall cotton supplies. Coffee prices lost nearly 5% after favorable weather conditions in Brazil, the world’s largest coffee producer, increased the chances of a large harvest in 2014.
Metals	Precious metal markets rallied after downbeat U.S. labor market data was released and caused investors to seek safe-haven assets. Copper prices experienced losses as demand fell following the release of data from Chinese banks which showed an increase in the pace of mortgage loan write-offs by large Chinese banks.
Currencies	The New Zealand dollar depreciated by more than 2% after the president of the country’s Reserve Bank announced his intention to keep interest rates low after new restrictions on home lending practices were recently introduced. The Swiss franc appreciated materially on concerns about China’s economic stability.
Equities	The Nikkei 225 lost more than 3% as a stronger yen negatively affected Japan’s export industries. The German DAX Index reached an all time high despite poor economic data out of Germany. The run up can be attributed to asset flows from the U.S. to Europe.
Fixed Income	30-Year U.S. Treasury Bonds gained almost 1% as sluggish economic data supported the Federal Reserve’s stance on continued capital injections. U.K. government bond prices appreciated on the same news.

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.
