According to Goldman Sachs' prime brokerage division, hedge funds purchased U.S. stocks last week at the fastest pace in six months, while the S&P 500 index continued its record-breaking rally. Goldman Sachs traders stated in a client report that the change in volume was driven by a combination of long buying and short covering in index products and exchange-traded fund products. Short positions in U.S.-listed ETFs decreased for a second consecutive week, falling by 0.6%. Sustained enthusiasm for investment in artificial intelligence infrastructure, coupled with better-than-expected earnings performance, jointly fueled the ongoing rally in U.S. stocks. The S&P 500 has risen for nine consecutive weeks, its longest winning streak since 2023. Meanwhile, the tech-heavy Nasdaq 100 index has gained over 20% this year. (Jinshi)
