Dear Investor,

2009 Closes with a Rapid Reversal in Fixed Income...

Inflationary fears subsided in December as better than expected U.S. economic
data fueled equity prices higher and bond prices lower. While market
participants seemed to be trading at reduced risk levels, price trends were
inconsistent leading into the holiday break, causing losses for many systematic
managers, including Campbell.

Enhancements to improve our agility in today's rapid market data flow
environment helped dampen losses in a number of sectors this month, despite
abrupt reversals in the U.S. Dollar and in Fixed Income. Gains in equity indices
trading also helped to dampen losses.

Commodity trading was mixed as cold weather in the U.S. led to volatility in the
energy complex overall. Gold traded to new all-time highs in the first three
days of the month only to drop over 10% from that high as the U.S. Dollar began
its rise.

Although 2009 performance is in line with industry returns, we, like you, are
disappointed in the lack of strong absolute returns. This difficult period for
the industry comes in the aftermath of recent Campbell underperformance, which
tends to overshadow Campbell's overall performance to investors during its
38-year history, where every drawdown heretofore was erased by new highs.

Considering the gravity and complexity facing the U.S. and the world in 2010, it
is hard to think of a more potentially favorable environment for managed futures
and Campbell & Company. Our ongoing commitment to innovation of our
systematically applied discipline will navigate Campbell through the exciting
challenges that 2010 suggests it will provide and, hopefully, back to levels of
expected relative and absolute performance.

Happy New Year to you and yours, and best wishes for good health, happiness, and
prosperity.

Sincerely,

Terri Becks
