Dear Investor,

Trend Following Strategies Struggle in September…

During the month of September, the Fund’s strategies recorded gains in the equity indices sector.  Offsetting losses came from foreign exchange, interest rates and commodities, resulting in overall losses for the Fund. The announcement of new quantitative easing measures from several central banks around the world and continuing developments in the Euro-zone were some of the major factors driving prices.  Trend following strategies typically have difficulty in this type of environment, however, diversity within the strategy helped to contain losses in the Fund.

The majority of September gains in the Fund came from the equity indices sector.  The Fund’s long positions in global stock index futures benefited from rising equity index prices on the back of several central bank announcements of new quantitative easing measures, China’s proposal for new fiscal stimulus, and the German high court’s ruling to uphold the constitutionality of the Euro-zone’s permanent bailout mechanism.

A portion of these gains were offset by losses experienced in the fixed income markets from the Fund’s long position in global government bond futures.  During a volatile month for bond prices, the U.S. 30 year contract finished the month almost 2 full points lower, as the market began to worry about the prospects of inflation.

Smaller losses were recorded in the foreign exchange markets from the Fund’s long positions in the European common currency vs. the U.S. Dollar.  The “Euro” squeezed higher during the month after the ECB announced a new bond buying program which appeared to reduce some of the near term tail risks around the ongoing Euro zone crisis.  Additional losses were recorded by the Fund’s trend models in the commodity markets from short positions in base metals as prices rallied sharply following the ECB’s commitment to buy unlimited bonds.

September finishes a relatively flat third quarter of 2012, and we look forward to maintaining a diverse portfolio with an absolute return objective through the remainder of the year.

Please do not hesitate to call us with questions

Sincerely,
