Fund results for July 2012:

          The Fund’s trading strategies returned to positive territory in July as capital preservation was the primary goal for investors. Unsustainable debt in Spain had government officials considering all options including bailout, default, or even leaving the euro while Greece’s troika of creditors found the country to be falling short of budgetary targets required for their 240 billion euro rescue package. China’s growth slowed to 7.6%, a three-year low, prompting two rate cuts so far this year. Investors seeking refuge redirected cash into safe haven debt instruments, pushing yields to record lows. In the U.S., the Great Plains growing region is facing the worst drought since 1956. Less than one-third of the U.S. corn and soybean crop is in good condition, propelling both markets to all-time highs. The Fund’s short-term strategies produced mixed results with gains in interest rates and losses in metals.

          The Fund’s equity positions underperformed in July. Volatility persisted as the overhang of European economic difficulties and slowing global growth continued to weigh on markets. Spain’s Ibex35 (-4.0%) fell to its lowest point since 2003 while the Italian Mib40 (-3.0%) reached an all-time low, prompting regulators to reinstitute short-sale bans in both countries. In the U.S., the Dow (+1.1%) was supported by a drop in jobless claims and encouraging durable goods data. In China (+1.1%), slowing growth prompted a second cut to its key lending rate while Japanese stocks (-3.7%) lost ground, pressured by the yen’s appreciation.

          The Fund’s bond positions were profitable in July as investors poured money into safe-haven debt instruments despite record low yields. Spain remains at the center of Europe’s economic woes with 10-year bond yields reaching 7.75%, a euro-era record. In response, investment into German bunds increased, which twice touched a record low yield of 1.127%. British Long Gilts (+2.3%) also benefited from safe-haven inflows as Bank of England officials announced another 50 billion pounds in quantitative easing. Robust demand for the safety of U.S. debt drove 10-year and 30-year yields to record lows as well, at 1.379% and 2.4405% respectively.

          The Fund’s allocation to short-term interest rates generated positive returns in July as markets welcomed action from the European Central Bank (“ECB”) while looking to the U.S. Federal Reserve (the “Fed”) to follow suit. The ECB cut its benchmark lending rate to a record low of 0.75% and its overnight deposit rate to 0% in an effort to stave off recession. Speculation for further cuts drove the Euribor rate to a record low of 0.401%. Markets expect the Fed may now reconsider cutting the IOER (interest on excess reserves) from 0.25% in order to incentivize banks to reallocate reserves away from the Fed and into higher yielding areas. Anticipation for an IOER cut, coordinated with additional Fed tools, lifted Eurodollar futures.

          The Fund’s allocation to currencies produced moderate gains in July as global economic uncertainly drove money flows into safe-haven sovereign currencies at the expense of the euro. A permanent solution to the debt issues that plague southern Europe remained elusive, pushing the euro to a two-year low versus the U.S. dollar ($1.2043/euro). The yen maintained its favored status, up 7.2% since mid-March, while the Aussie dollar (+2.9%) also remained strong. The Canadian dollar (+1.5%) approached parity with its U.S. counterpart on relative economic outperformance.

          The Fund’s strategies produced strong returns in grains in July as the U.S. Midwest is experiencing its worst drought in nearly six decades. As of July 30^th, only 25% of the crop was in good condition, the lowest since 1988. The USDA lowered yield estimates 12% to and is expected to make another significant cut in August. December corn gained 27% in July and is 59% higher since mid-June. It is likely that later maturing soybeans will be equally affected by the drought. The most active corn and soybean contracts posted all-time highs of $8.20 ½ and 16.91 ½ a bushel respectively.

          The Fund’s positions in the metals sector underperformed in July as Comex gold continued to trade in a narrow range and global instability hurt base metal demand. LME warehouse zinc (-1.9%) supplies surpassed one million metric tons for the first time in 17 years while copper imports to China fell to a 10-month low. Comex copper declined 2.1%, closing at $341.75/lb. Gold was confined to a 4.6% range as traders awaited signals from central bankers towards easing policies.

          The Fund’s allocation to the energy sector yielded disappointing results in July as crude oil mounted a rally from the dramatic decline over the last several months. Short-covering helped to start prices moving up early in the month as speculators sought to lock in gains. Rising political tensions between Israel and Iran helped to reinforce the rally with unrest in Syria increasing the likelihood of a near-term supply disruption. RBOB gasoline (+6.9%) and heating oil (+5.4%) moved up sharply in step with crude, in spite of ample supplies. Natural gas (+13.6%) rebounded further from lows as hot weather drove up cooling demand from utilities.

          The Fund’s perpetual long gold position posted modest gains in July as gold remained bound to its established trading range, crossing the $1,600/troy oz. level ten times since early May. Forecasters disagree on market direction with bulls anticipating central bankers being forced to implement further monetary easing while bears cite waning interest and preference for the U.S. dollar.
