According to Wu, The Kobeissi Letter reports that this Thursday, hedge funds sold off $40 billion in stocks, marking the largest single-day sell-off since 2010, with short selling volume exceeding long positions by three times. North American stocks accounted for 75% of the trading volume, and the market seems to be approaching a "surrender" phase. On the same day, retail investors, in contrast, bought $4.70 billion in stocks, the largest single-day purchase since 2015. However, from 9:30 AM to 12:00 PM on Friday, retail investors sold off $1.50 billion, marking the largest sell-off within 2.5 hours, indicating a potential rapid reversal in the buying trend.
