AQR Capital Management, through its "Flex strategy," utilizes shorting and leverage to generate tax-deductible losses for clients while the portfolio still appreciates in value. For example, a $100 million investment can generate over $580 million in tax-deductible losses over 10 years. As of the end of March 2026, AQR's assets exceeded $140 billion. However, U.S. Treasury officials warned in July 2026 that some new strategies were producing unintended outcomes by Congress and could involve "abuse." Charles Schwab and Fidelity are currently restricting new accounts pursuing this strategy.
