Becks ----------------------------------------- Theresa D. Becks, Chief Executive Officer Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust Prepared without audit Dear Investor, Currency gains dampen losses in equities and bonds... Trading in the foreign exchange sector produced gains this month, primarily as a result of the US Dollar rally against key funding currencies, despite a generally weak global economy. Minimal gains were recorded in the commodities sector as Campbell's technical models took advantage of escalating prices as access to petroleum supply continues to tighten. Losses were recorded in both the interest rates sector and in equity indices trading as prior trends reversed their course. US treasury prices declined in a technical break as curve flattening continued. Global equity prices reversed their downward trend amid the optimistic belief that the worst news had passed. Recent enhancements have allowed our models to operate: (1) with greater sensitivity to short-term market correlations; and (2) with greater overall agility to consider risk factor correlations. Uncertain economic times, such as these call for cool heads and a disciplined approach to investing. As such, we are optimistic that our robust research infrastructure should result in improved performance, particularly in response to changing market dynamics. Thank you for your continued partnership and please do not hesitate to contact me with further questions. Sincerely, Terri Becks President & CEO Campbell & Company, Inc.
