Becks ----------------------------------------- Theresa D. Becks, Chief Financial Officer Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust Prepared without audit Dear Investor, Energy losses overshadow gains from nascent trends ... Markets with light volume and little momentum resulted in small negative returns for Campbell & Company's portfolios in August. With many traders on vacation, the summer doldrums reflected the state of many of the sectors we trade, and even the notoriously fickle but volatile Energy markets were mostly range-bound. The Energy sector was dominated by perceptions of an easing in global geopolitical tensions, a mild hurricane season (so far!), and steadily rising inventories. These factors led to a sharp sell-off in Natural Gas (down by 30%) and Crude Oil (fell below $70 per barrel). Also negative for our portfolios (but welcome news at the pump!), Unleaded Gasoline traded down more than 40 cents in August alone. Trading in non-dollar currency positions was profitable, but outright US Dollar positions resulted in losses. Positive returns were also earned in long-dated Interest Rate instruments and Stock Indices, with both rallying sharply from mid-summer lows. The recent market environment has not been conducive to our style of trading, and for this reason commitment levels are lower than they have been in a very long time. However, market trends often strengthen as we head towards the end of the year, and we remain confident that over the intermediate to long-term our strategies will continue to add value to our clients' portfolios. In the meantime, if you have any questions, please do not hesitate to contact me. Sincerely, Bruce Cleland President & CEO Campbell & Company Inc. Managing Owner
