Goldman Sachs has identified a potential short squeeze rally in U.S. stocks, driven by the recent surge in bearish bets. According to S3 Partners LLC, short positions have increased by nearly $100 billion, reaching $2.13 trillion, the highest since 2010. Goldman Sachs reports that the median net short position for S&P 500 components has climbed to 3% of market capitalization, the highest since 2011. The trading desk at Goldman Sachs suggests that the next market upswing may result from short covering rather than continued growth in large technology stocks. Analysts Gail Hafif, Brian Garrett, and Lee Coppersmith highlight the potential for gains in less favored sectors as investors move away from momentum-driven trades.
