Charles Schwab CorpCharles Schwab is limiting new accounts for tax-loss strategies, facing regulatory scrutiny.

AQR Capital Management has become the world's largest hedge fund, surpassing $140 billion in assets by the end of March 2026, driven by aggressive tax-loss harvesting strategies that manufacture losses for wealthy investors. The firm's Flex strategy can turn a $100 million investment into over $580 million of tax-offsetting losses over 10 years using shorts and leverage, while a second product, Delphi Plus, targets annual income sheltering. Treasury officials warned in July 2026 that such strategies may be 'potentially abusive' and produce outcomes Congress never intended, and Charles Schwab and Fidelity are limiting new accounts pursuing the strategy. AQR has added a disclosure that the IRS could retroactively bar the benefits, and short sellers are wagering on a government crackdown.
