📈 S&P 500 Loses $850 Billion in Market Cap on May 21, 2025

On May 21, 2025, the S&P 500's total market capitalization dropped by $850 billion (-1.61%) to $52.0 trillion. The sell-off followed a poorly received Treasury bond auction that sent yields sharply higher, sparking renewed concerns about U.S. fiscal stability due to proposed debt-related legislation. Technical indicators pointing to an overbought market, along with broad-based sector declines and a flight to safer assets, further accelerated the decline.
