Becks ----------------------------------------- Theresa D. Becks, Chief Executive Officer Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust Prepared without audit Dear Investor, Diversification Helps Reduce Losses in May... As European sovereign debt concerns persist and China tightened credit in an attempt to cool overheating in its property sector, the decline in equity markets by month-end was wide-spread across the U.S., Europe, and Asia. Certainly the "flash crash" on May 6th only added to the unsettling nature of equity market price behavior throughout the month. While the Trust experienced losses in equity indices, gains in fixed income help offset the flight from risky assets in favor of government debt. Commodity trading was difficult for the Trust, particularly in the Energy sector, as the complex fell in tandem with the equity markets until a late month bounce. While BP's spill in the Gulf continued to flow uncontrollably, the disaster has not significantly affected the supply of oil into the U.S. to date. Along with the scare in Greece, the Euro came under pressure against the U.S. Dollar as comments from Federal Reserve Chairman Bernanke raised concerns over the Euro zone's bank funding. The U.S. Dollar was, once again, viewed as a safe position trade as risk aversion, volatility and liquidity dominated currency markets contributing to gains in the Foreign Exchange sector for the Trust. As we confront the emotional state of the markets, we take comfort in our systematic discipline and ability to manage through market volatility with diversity in our portfolio exposures. We look forward to answering any questions you may have. Sincerely, Terri Becks President & CEO Campbell & Company, Inc. Managing Owner Campbell Alternative Asset Trust
