Dear Investor,

Foreign Exchange losses edge out gains in Interest Rates....

The global economic environment in August was dominated by a stronger U.S.
dollar and the energy complex falling out of favor.

The Fund experienced the majority of its losses for the month in Foreign
Exchange trading as commodity-linked currencies fell in tandem with metal and
energy markets. The U.S. Dollar Index posted unusually strong gains of nearly
6%, with other major currencies losing over 3%. Campbell's currency models
reacted with agility, reversing their course and dampening further losses in
this sector.

Small losses were recorded in commodity trading, despite the severity of the
energy and metal complex downturn across the board. Natural gas led the way for
the energy sector with a market price decline of 12.75%, while gold fell to its
lowest level in eight months.

Gains in Interest Rates trading were largely driven by foreign central bank
activity as they increased purchases of U.S. Treasuries, pushing prices higher
for a third straight month.

Trading results in Equity Indices were relatively flat despite a positive finish
in U.S. equity markets. European markets were mixed in seasonally low volume,
while Asia was generally lower. The Japanese economy continued to show signs of
deterioration, and Chinese markets persisted in their relentless plunge lower.

Sub-prime fallout continues to plague financial markets globally, the U.S.
unemployment rate hit a four-year high, and the U.S. presidential election
process is well under way. It should be an interesting fall.

Please do not hesitate to call if you have any questions.
