Becks ----------------------------------------- Theresa D. Becks, Chief Executive Officer Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust Prepared without audit Dear Investor, Following an excellent second quarter and a promising start to July, a sudden flight to quality, the unwinding of the carry trade, and a highly correlated, unusually large move against our positions resulted in one of our largest monthly declines in recent years. While statistically we understand that losses of this magnitude can occur, the speed of this decline caught us all by surprise. Losses were broadly based and evenly spread between the Interest Rate, Foreign Exchange and Equity Index sectors. Statistical measures of Campbell's daily portfolio risk were normal and inside historical ranges, but the move against our portfolio was not. The losses were experienced in most markets and across most models. In response to this "perfect storm", we have temporarily cut our leverage by 50%. We will continue to monitor market behavior together with our own measures of portfolio risk and correlation and expect to move back to normal leverage levels in the not-too-distant future. We take some comfort from noting that sharp increases in market volatility such as we have seen recently often set the stage for an opportune trading environment. In the meantime, our commitment to a disciplined, diverse, systematic trading strategy with a strong emphasis on risk management remains unchanged. We appreciate your patience and understanding during this challenging period. As always, if you have any questions or concerns, please do not hesitate to call. Sincerely, Terri Becks President & CEO
