Fund results for September 2010:

The Fund’s allocation to global equities proved successful in September as equities moved sharply higher. While investor sentiment remained muted, indices in the U.S. broke out to the upside as the combined effects of excellent technology earnings and elevated M&A activity drove the Nasdaq index 13.1% higher. News that the Federal Reserve has its finger on the trigger of a second round of quantitative easing also put a floor under the market as the resulting U.S. dollar weakness made investing in U.S. shares more cost effective. European equities also responded positively, ignoring lingering sovereign debt concerns, ongoing strikes, and disappointing German retail sales and factory orders. Short positions in the Dow Jones Eurostoxx (+5.0%), France’s Cac-40 (+6.4%) and Spain’s Ibex (+2.5%) experienced losses as rising exports led to improving executive and consumer confidence. Long positions in Korea’s Kospi index (+7.4%) performed well amid upward revisions in the country’s current account surplus.

Long positions in short-term interest rate products yielded negative returns as the majority of these markets finished the month on the downside. The long-term upward trend in Canadian3-month bank acceptance and Australian90-day bank bill futures reversed, resulting in losses for the Fund’s short rates allocation. The selloff in Canada was attributed to the Bank of Canada raising rates by 25 basis points for the third time since June, along with a better than expected rebound in Canadian employment and household spending. Australian short rates sold off dramatically in response to employers adding more jobs than forecast and the RBA stating that rate increases are likely if the economy continues to expand at its trend pace. In the U.S., 3 month Eurodollar futures bucked the global trend, trading higher as better than expected economic data was overshadowed by statements that the Federal Reserve is prepared to implement a second wave of unconventional monetary easing.

The Fund’s allocation to currency markets experienced strong gains in volatile action during September amid profound dollar weakness. Negative dollar statements by the Federal Reserve served as a catalyst for extreme currency market moves worldwide. The Australian dollar led the way, advancing over 9.0% and approaching parity with the U.S. dollar as interest rate differential prospects for the pair widened. Japanese authorities surprised the world with a unilateral intervention on September 15th designed to defend the viability of their export market. However, by month-end, the yen had regained most of the single day 3.0% loss amid doubts surrounding the Bank of Japan’s ability to see the plan through. Long positions in the Swiss franc (+3.5%) yielded returns for the Fund as investors perceived a safe haven play with the yen and dollar in tumult. Emerging market currencies also performed well as the South African rand (+6.0%), Brazilian real (+3.7%), and Korean won (+4.8%) gained due to surging equity markets attracting capital.

The Fund yielded strong results from its allocation to the metals markets in September as investors sought safety from the devaluation of fiat currencies and exposure to alternative assets. Gold spent the latter half of the month making a new all-time high on a daily basis as the dollar collapsed to a seven-month low. Long positions in December gold (+4.7%) and silver (+12.2%) benefitted with gold surging to over $1,300 per ounce and silver breeching a30-year high. Long positions in base metals performed well as positive early month manufacturing readings in the U.S. and China sent copper futures higher. London copper added 8.5% amid falling inventories while aluminum and nickel posted gains of 14.7% and 12.4%, respectively.

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

For the month of September 2010, Series A gained 4.55% and Series B gained 7.45%, including all fees and expenses.
