Becks ----------------------------------------- Theresa D. Becks, Chief Financial Officer Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust Prepared without audit Dear Investor, Energy losses overshadow Equity gains... The biggest losses occurred in the energy complex where crude prices fell over 11% and heating oil and unleaded gasoline both fell around 14%. The drop in prices was driven by the lack of hurricane activity, a further easing of geopolitical tensions, and adequate physical supplies amid the warmer-than-normal autumn season. Trading in equity indices was positive as economic data (with the exception of housing-related figures) continued to show moderate growth with restrained inflation. Gains were also recorded in currency markets, where losses on our cross rates exposures were more than offset by gains on our outright positions, despite the historically low volatilities in many of these markets. Small losses were recorded in Fixed Income as the market continued to believe that the US Fed will not raise rates again in the foreseeable future. On a personal note, you will notice over the next couple of months that these comments will be authored by one of my colleagues. I will be away from the office for periods of time receiving treatment for an oral cancer with which I was recently diagnosed. I look forward to authoring these comments again as soon as my treatment is concluded. Sincerely, Bruce Cleland President & CEO Campbell & Company Inc. Managing Owner
