Fund results for February 2010:

World bond markets experienced volatile action as sovereign debt contagion worries spread while economic data showed promising signs. Our net short position inU.S. 30-year Treasury bonds fell prey to small losses as futures rallied near month end despite better than expected economic reports. The unemployment rate fell to 9.7% while manufacturing expanded at the fastest pace since August 2004. The Federal Reserve’s willingness to raise the discount rate by 25 basis points provided additional positive macroeconomic sentiment. In Europe, March bunds surged into month end to finish moderately higher, producing gains. Bunds rallied as some European nations continued to struggle with growing budget deficits, which led to declining business confidence. Ten-year Japanese bonds sold off in early February as annual GDP rose 1.1% more than forecast. However, our long futures position recovered to produce minor gains after the GDP price deflator fell by the largest amount in 54 years. Overall, a mixture of long and short positions produced gains in the bonds sector.

Global short-term interest rate futures traded higher in February, continuing astrong-upward trend and providing our funds with positive returns. In the U.S., three-month Eurodollar futures rallied to new highs after the Federal Reserve unexpectedly raised the discount rate but reaffirmed that the federal funds rate will remain at exceptionally low levels for an extended period. Consumer prices rising less than forecast also supported buying as short-term inflation fears diminished. The Fund’s long position in three month Sterling futures benefitted after the Bank of England cut its forecast for economic growth, stating that inflation will undershoot its target. Another factor supporting the rally was a report showing that U.K. retail sales dropped twice as much as forecast. Australian90-day bank bill futures spiked dramatically higher after the Reserve Bank of Australia unexpectedly left interest rates unchanged at 3.75%. The central bank stated its intention to stop and assess the economic impact of the previous three rate hikes. The Fund’s long positions led this sector to a gain.

Our positions within the grain complex positions yielded negative returns in February as fundamentals improved enough to offset the U.S. dollar rally. The U.S. Department of Agriculture reduced U.S. soybean ending stocks for2009-10 to 210 million bushels, down 35 million bushels from last month. A 25 million bushel increase in soybean exports contributed to the downward revision in ending stocks as shipments continued to exceed previous projections. May soybeans gained 3.9% by month’s end, strengthening enough that our trading model initiated new long positions. May wheat prices added 6.3% in February, reversing January’s decline while producing losses for our short positions. The rally was buoyed as Australia lowered its 2009-10 crop forecast by 1.5% to 21.66 million metric tons. The crop suffered as extreme heat was followed by heavy rains. Our short May corn position also lost ground as the market rallied 5.7% after the U.S. Department of Agriculture revised ethanol use 100 million bushels higher than expected. A mixture of long and short positions led this sector to a loss.

We experienced solid returns in global energy markets in February as macroeconomic data continued to impress. The Fund benefitted as April crude oil futures rose 8.5%, finishing near the $80 level as U.S. manufacturing expanded at the fastest rate since 2004. Meanwhile, the combination of stellar U.S. corporate earnings and the Federal Reserve feeling confident enough in economic performance to raise the borrowing costs of banks by 25 basis points contributed to gains. That said, front-month crude futures remained in the loose trading range between $65 and $85 established since early fall of 2009. Despite harsh winter weather in key North American heating regions at the beginning of February, the ample supply of gas proved too much to keep prices high for long. Prospects for milder weather improved as the month wore on, sending natural gas futures lower and providing the Fund’s trading model with strong results. Front-month futures finished 6.1% lower while moving below the psychological $5/million Btu level. A mixture of long and short positions led this sector to a gain.

Our allocation to agricultural and softs markets disappointed in February as New York and London front-month sugar futures reversed sharply, falling 19.2% and 9.8%, respectively. The old adage that “high prices are the cure for high prices” rang true as Brazilian farmers stepped up production while Egyptian and Pakistani importers backed away from purchasing new product at the highs. Meanwhile, early in the month European Union regulators proposed allowing additional exports of 500,000 metric tons. We also lost some ground on our long cocoa position despite unrest in the Ivory Coast as the rising U.S. dollar and huge European inventories weighed on values. The reversal in May New York cocoa led to a loss of 10.2% on the month. Meanwhile, cotton produced gains, reestablishing its upward trend after a one-month lapse as exports for the first six weeks of the year surged 93% over 2009. Chinese production is now estimated to have fallen 15% for 2009, propelling May cotton to near two-year highs and a gain of 16.7%. A mixture of long and short positions led this sector to an overall loss.

Other market sectors did not reveal significant trends and did not have a significant influence on this month’s overall positive performance.

For the month of February 2010, Series A gained 1.49% and Series B gained 2.60%, net of all fees and expenses.
