Becks ----------------------------------------- Theresa D. Becks, Chief Financial Officer Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust Prepared without audit Dear Investor, A Choppy First Quarter... March ended almost flat as the theme of range-bound, choppy markets continued in most sectors. Our gains were primarily in Interest Rates, as both short-term and long-term positions proved profitable, and the Energy sector where crude and products prices made new highs. The US Dollar closed higher for the month, reversing the long-term downtrend, and was a negative for our positions. We also incurred losses in our non-dollar Currency positions, making this the worst performing sector in Q1. Equity Index markets also reversed and ended the month lower, with resultant losses to our portfolios. The current interest rate environment continues to be a very difficult one and has arguably contributed to the lack of direction in many of the other markets we trade. This condition may continue for some time. While reporting monthly flat performance is certainly easier than reporting losses, delivering attractive absolute and risk-adjusted returns remains our primary goal. Extended periods of flat or poor returns along the way are inevitable, and we shall not falter in our commitment to maintain the discipline which we know is so important for success in the longer term. Sincerely, Bruce Cleland President & CEO
