Becks ----------------------------------------- Theresa D. Becks, Chief Financial Officer Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust Prepared without audit Dear Investor, Sharp reversals in extraordinary times... August was a disappointing month in which sharp trend reversals occurred in each of the major financial sectors, resulting in significant losses in all of our portfolios. The tragedy that struck the US Gulf Coast at the end of the month was stunning in scope, and its impact will be felt in the coming months, but it was a series of major trend reversals that generated the losses in August. Currencies were our worst performing sector. The US Dollar peaked at the end of July, then reversed sharply and traded close to its recent lows at the end of August. A similar reversal occurred in the Interest Rates sector, resulting in losses at both ends of the yield curve. Equities trended higher in July, but record energy prices caused a sharp sell-off and resulted in losses in this sector. Energy was the only profitable sector in our portfolios this month, but the size of positions was not sufficient to offset the losses incurred in the financial sectors. While these losses certainly hurt and there is no room for sanguinity, to "give back" some of our recent gains is not in itself unusual and we continue to be profitable on a year-to-date basis. We appreciate your continuing confidence and will continue to work hard, maintain our discipline, and look for better days ahead. Please do not hesitate to call for assistance. Sincerely, Bruce Cleland President & CEO
