Market Commentary (Largest price movements within each sector)

Sector/Market
Energy	Crude oil markets moved nearly 7% higher as a bullish employment report for June boosted industrial demand forecasts. Prices rose in response to concerns civil unrest in Egypt could result in supply disruptions in the Middle East. Natural gas markets also rallied, driven by forecasts for warmer temperatures in the U.S.
Grains/Foods	Corn prices rose due to concerns surrounding tight U.S. supplies and steady demand from ethanol producers. Sugar prices fell as industry reports forecast ongoing strong production from Brazil. Cotton prices rallied due to heavy buying by commodity funds that attempted to take advantage of recent price declines.
Metals	Gold and silver markets experienced declines as a late-week surge in the U.S. dollar put pressure on prices. Copper markets finished higher, supported by early-week gains fostered by declines in global inventories. Other base metals, including aluminum, tin, and nickel, did not fare as well as concerns surrounding the Eurozone and tensions in Egypt put pressure on industrial demand forecasts.
Currencies	The U.S. dollar strengthened against global counterparts following the employment data report that beat forecasts. The euro reached a 5-week low against the dollar due to comments from the ECB which suggested measures to facilitate growth in the Eurozone could continue for an extended period. Political tension in Portugal also played a role in the euro’s decline.
Equities	North American equity markets rose due to a sharp late-week rally supported by a bullish employment report. The Japanese Nikkei 225 also posted strong gains, supported by the bullish effect of a weaker yen on the nation’s export industries.
Fixed Income	Global fixed-income markets registered mixed results last week. U.S. Treasury markets fell sharply as positive economic data in the U.S. supported forecasts for an upcoming reduction in Federal Reserve bond-buying initiatives. Conversely, German Bund markets rallied higher as comments from the European Central Bank suggested the Eurozone may require further stimulus to aid growth in the region, which supported safe-haven demand.

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.
