Dear Investor,

Profits from Currency trading dominate in October

Mixed messages dominated trading in October as corporate earnings' reports
either beat estimates or severely disappointed, money center and investment
banks continued grappling with major credit related losses, housing data
continued to soften, and the FOMC complied with market expectations with a 25
basis point cut on the last day of the month.

Gains from currency trading led the way in October as the US Dollar continued
its descent - breaching historic support levels. High yielding currencies
continued to battle back from August lows and Campbell benefited from its
positive positioning to the global risk environment.

Additional gains were recorded from trading in global equity indices, despite
intra-month volatility. US markets finished strongly, with the NASDAQ 100
leading the charge, Europe continued to move higher (albeit at a slower pace),
and Asian stock indices traded within a 7% range only to finish flat.

Fixed Income trading finished flat with yields at month end falling across the
curve as credit quality remained an underlying concern. Energy and base metals
trading finished slightly lower as the tight supply demand picture has been
coupled with a deteriorating geo-political landscape, a weakening dollar and
strong growth from India & China.

As always, we remain committed to a disciplined, systematic approach to managing
your investment. Please do not hesitate to contact me if you have any questions.

Sincerely,

Terri Becks
