Dear Investor,

Fixed Income, Currencies and Commodities Yield Positive Performance for April...

April performance was led by strong gains in the fixed income markets from long
positions in Europe and from U.S. Bond prices that moved higher during the month
as the Greece sovereign debt concerns and fears of contagion played center stage
in global markets. Currency trading also benefited from the sovereign debt fears
and from perceived signs of positive economic growth beginning to materialize.
Further gains were recorded in energy and precious metals, as energy markets
continued its high correlation to the S&P and investor demand for precious
metals continued to grow. Marginal losses were incurred in base metals trading
as these markets moved lower on U.S. dollar strength.



Global equity indices trading produced flat performance, with net longs across
the board producing positive results in the U.S., negative results in Europe,
and flat performance in Asia.

Investors continue to be provided with fragmented predictions of economic
recovery, coupled with concerns over the recent strong market gains and
sovereign debt contagion. These types of ambiguous market signals bode well for
systematic disciplines by minimizing the human emotions one can easily succumb
to during these times.

Should you have any questions or concerns, please don't hesitate to contact me.

Sincerely,

Terri Becks
