Recent market data reveals substantial imbalances across major U.S. equity indices over several days. On June 11, the S&P 500 experienced a market-on-close (MOC) imbalance of negative $1.06 billion, NASDAQ 100 fell by $379.6 million, Dow 30 declined by $620.2 million, and the MAG 7 group dropped by $161.6 million. Similar imbalances persisted on June 12 and June 13, with fluctuations including a positive MOC imbalance of $1.22 billion for the S&P 500 on June 13. Concurrently, institutional investors have been net sellers of U.S. equities, offloading $4.2 billion last week alone, according to Bank of America data. Over the past four weeks, average weekly institutional selling reached $2 billion. In contrast, retail investors have been net buyers, purchasing approximately $700 million last week and generally buying on market dips. This divergence highlights a historic sentiment gap between bearish professional investors and bullish retail traders. Additionally, U.S. equity funds have experienced their largest outflows in nearly three months, underscoring the ongoing market tension between institutional and retail participants.
