In this article, we talk about the 15 stocks with the biggest hedge fund momentum.
On February 23, Bloomberg News reported that during the week ended February 19, hedge funds registered record-high net sales of global stocks, the highest since early April 2025. Despite the selling spree, hedge funds maintained solid performance in early 2026, a period characterized by choppy markets and including the worst single-day drop for three major fund strategies since the COVID-19 pandemic.
Goldman Sachs Group Inc.’s Prime Services Desk said, “All major regions were net sold, led by North America and Europe. Single stocks and macro products were both net sold and made up 58% and 42% of the total notional net selling, respectively, both led by short sales.”
Meanwhile, JPMorgan told its clients in a note that hedge funds bought the largest tech stocks last week, according to a Reuters report from February 24. Hedge funds also bought shares in companies considered vulnerable to advances in artificial intelligence. Software stocks saw some buying after being sold down by historic amounts the week before, JPMorgan added.
Goldman Sachs also said that hedge fund leverage is nearing its highest level in a year, noting that net sales orders in global equities hit their highest level since U.S. President Donald Trump announced a barrage of import tariffs last April.
With that said, here is the list of the 15 stocks with the biggest hedge fund momentum.
