The downturn came as the U.S. Treasury boosted buybacks and Moderna shares surged. This volatility follows a tumultuous July, during which hedge funds faced significant underperformance relative to the S&P 500.

According to Goldman Sachs, this underperformance was the worst in over 20 years of recorded data. The market turbulence has led to a reshaping of investment logic for AI, with Goldman Sachs noting extreme volatility in the U.S. equity market. Hedge funds, including Rokos and Brevan Howard, were caught off guard by the July market havoc.

Despite the volatility, some hedge funds are doubling down on Big Tech investments. The next steps for these funds will depend on how they navigate the current market conditions and adjust their strategies in response to the ongoing volatility.
