US stocks see biggest exit since March: is Wall Street’s rally at risk?

US stock funds saw their biggest weekly exit since March, raising fresh questions about the strength of Wall Street’s rally.

Investors pulled US$17.2 billion (approx. $30.1 billion) from US stock funds in the week through July 1, according to Bloomberg, citing Bank of America strategists led by Michael Hartnett and EPFR Global data.

The move does not signal a market crash, but it does show investors are turning more cautious after a strong run in US equities.

The key question now is simple: is this routine profit-taking, or an early warning that confidence in the AI-led rally is starting to fade?

Wall Street's rally loses its flow cushion

Fund flows work like a sentiment gauge as they show whether investors are adding fresh money to equity funds or quietly taking some risk off the table.

A US$17.2 billion (approx. $30.1 billion) weekly exit does not mean the S&P 500 is collapsing, but it indicates that investors are becoming more cautious after a powerful run in US equities.

That matters because this rally has leaned heavily on megacap technology, AI optimism and confidence that corporate earnings can keep absorbing higher rates.

When money is still pouring in, expensive markets can keep climbing, but when flows turn patchier, valuations become more exposed to bad news.

The shift did not appear from nowhere as US equity funds already saw US$3.5 billion (approx. $6.2 billion) of outflows in the week to June 24, as worries over debt-funded technology spending and hawkish Federal Reserve expectations weighed on sentiment.

Technology sector funds saw nearly US$20 billion (approx. $35 billion) of withdrawals that week, reversing the previous week’s inflows.

That makes the latest BofA number less of a surprise and more of a continuation and a signal that investors are no longer buying every dip with the same confidence.

Tech fatigue is becoming harder to ignore

The pressure point remains technology. The AI trade has been the engine of Wall Street’s advance, but it is also where concentration risk is highest.

The MSCI World Index fell 2.07% last week amid worries over concentration risks and hyperscalers’ spending plans.

Those concerns matter because investors are watching whether cloud giants can turn massive AI capex into durable profits, not just bigger bills.

BNY’s Bob Savage told Reuters that the AI-led equity rally was showing signs of fatigue.

That is the kind of line that lands because it captures the market’s current mood: still bullish on AI in principle, but less willing to ignore every valuation warning.

Oliver Shale, investment specialist for the US at Ruffer, made the positioning risk clearer.

He said that through the lens of valuations, positioning and sentiment, risk measures are “flashing amber.”

Rotation, not full retreat

The more balanced reading is that investors are rotating, not giving up on equities altogether.

LSEG data showed global equity funds pulled in US$10.4 billion (approx. $18.3 billion) in the week to July 1. Asian equity funds attracted US$7 billion (approx. $12.3 billion), their biggest inflow in seven weeks, while US funds saw a smaller US$1 billion (approx. $1.8 billion) inflow.

Technology funds also rebounded with US$8.9 billion (approx. $15.6 billion) in inflows after the previous week’s heavy selling.

That complicates the bearish case. Investors may be trimming crowded US exposure while still buying technology and other regional equity opportunities.

William Bratton, head of cash equity research for APAC at BNP Paribas, struck that tone in a note cited by Reuters.

He said the bank’s tech analysts saw “no reason” for the sector’s earnings momentum to slow or reverse in the near term, with the coming second-quarter earnings season expected to be supportive.
