AI Frenzy Cooling Down? Bank of America Warns: U.S. Stock Funds Saw $17.2 Billion in Withdrawals in a Single Week, Institutional Investors Slash 'Single Tech Stock'

AI Party Takes a Mid-Season Break? According to the latest fund flow report released by Bank of America, for the week ending July 1, 2026, U.S. stock funds suffered a massive outflow of $17.2 billion, marking the largest bloodletting in nearly four months. This sell-off, driven by institutional investors, has hit the overheated tech and financial sectors hard, with net outflows from single stocks reaching tens of billions of dollars. Market capital clearly exhibits defensive traits such as "shifting from stocks to ETFs" and "sector rotation."

• Institutional giants lead the sell-off, single stocks see nearly $10 billion in outflows

• AI trade cools, fund rotation and macro hedging become the main themes

After a frenzy of rebounds and capital surges in the first half of the year, the U.S. stock market seems to be entering a period of sharp cooling. According to the latest report from Bank of America (BofA) citing EPFR Global data, for the week ending July 1, 2026, U.S. stock funds saw a net outflow of as much as $17.2 billion, the largest weekly bloodletting since March this year.

The emergence of this data is highly dramatic. Just the previous week, some market reports recorded a staggering net inflow of approximately $119 billion. Now, this $17.2 billion withdrawal not only mercilessly ends the three-month streak of net inflows into U.S. stock funds but also sends a strong signal that investor sentiment is undergoing a major shift.

Institutional giants lead the sell-off, single stocks see nearly $10 billion in outflows

A closer look at the structure of this capital exodus reveals that "institutional investors" are the absolute leading force in the sell-off. BofA's client data shows that this marks the fourth consecutive week that institutional investors have been on the sell side (net selling).

The most alarming aspect is the precise selling of "single stocks." In that week, net outflows from single stocks reached as high as $9.9 billion to $10 billion, marking the "fourth-largest single-week sell-off in history" since the record began in 2008. In contrast, retail clients turned net buyers for the first time after six consecutive weeks of selling, while hedge funds also stood on the buy side, indicating a fierce handover of market chips.

AI trade cools, fund rotation and macro hedging become the main themes

This fund flow report perfectly echoes the Wall Street hot topic of "AI/tech trade cooling." In late June, as megacap tech valuations were pushed to extremes, tech funds began experiencing record outflows, indicating that smart money is taking massive profits. Investors are no longer blindly chasing overvalued AI concept stocks but are rotating funds into value stocks, small caps, and even non-U.S. markets with relatively reasonable valuations (such as some emerging markets).

Furthermore, the clear preference for ETFs (about $4.2 billion in inflows) while dumping single stocks suggests that the market is leaning toward safer passive index tools to diversify overly concentrated stock risks. Looking ahead, Bank of America specifically points out that its "Bull & Bear Indicator" is rising, which is typically a cautious signal for the market. With the Fed's rate cut path unclear and upcoming earnings season and employment data tests, the major reshuffling of U.S. stocks is likely to continue.
