Dear Investor,

Investor Risk Sentiment Improves in July...

Contrary to investor fears, global stock market returns in 2009 have fueled
improved risk appetite as economic data and corporate earnings support the rally
for yet another month. The Trust's trading performance was relatively flat for
July, with positive results from long stock and short U.S. Dollar positions
being offset by losses incurred from short interest rate positions.

For the first half of 2009, many "trend-following" strategies have struggled to
curb losses and eke out small gains in a market environment that is in a classic
"consolidation" (trendless and choppy) period. The effect of this consolidation
is particularly frustrating for many investors who have already lived through
the disappointment that 2007 and 2008 performance results have fostered.
Campbell has recently completed the latest of several initiatives to enhance its
ability to make money on the offense, and not just play defense and dampen
portfolio volatility.

Campbell maintains our commitment to ongoing research initiatives regardless of
performance. As a result of the increased speed in the dissemination of market
information and growth in market participants, the markets have reflected a
greater propensity to shift risk appetite swiftly, with little pause. This shift
requires Campbell to improve model agility and capability, to not only diversify
by information source and by instrument, but also to diversify by investment
style and look-back period. This has been our concentration since the "perfect
storm" events of 2007. As newer sub-models (of core constituent models at
Campbell) come into production, we can anticipate the benefit of a more dynamic,
more nimble portfolio.

We believe that prudent, evolutionary change will lead us out of this lackluster
performance era and back to healthier, both relative and absolute, returns for
our clients. Campbell's 37-year history in the investment management business
speaks to our ability to endure the difficult times and potentially provide
rewards for staying the course.

Please do not hesitate to call with questions.
Sincerely,

Terri Becks
