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

• Technology sector concentration risk is rising as investors question whether cloud giants can convert massive AI capital expenditures into sustainable profits
• Asian equity funds attracted $7 billion in the same week, their largest inflow in seven weeks, suggesting regional rotation rather than broad equity exodus
• Risk indicators are 'flashing amber' according to investment specialists, with valuation, positioning, and sentiment measures showing caution despite expectations for supportive Q2 earnings

Market Summary: US Stock Outflows Signal Growing Caution

Key Developments

US stock funds experienced their largest weekly outflow since March, with $17.2 billion withdrawn in the week ending July 1, 2026, according to Bank of America strategists citing EPFR Global data. This follows a $3.5 billion outflow the previous week ending June 24.

Sector Focus: Technology Under Pressure

Technology funds saw dramatic volatility, recording nearly $20 billion in withdrawals in late June before rebounding with $8.9 billion in inflows the following week. The MSCI World Index declined 2.07% last week amid concerns over AI concentration risk and hyperscaler capital expenditure sustainability.

Market Implications

Analysts characterize the outflows as increased caution rather than panic, with rotation evident across regions. While US funds shed capital, global equity funds attracted $10.4 billion overall, with Asian equity funds drawing $7 billion—their strongest inflow in seven weeks.

Industry experts describe the situation as "flashing amber" on risk measures including valuations, positioning, and sentiment. The core concern centers on whether cloud giants can convert massive AI infrastructure spending into sustainable profits.

Outlook

BNP Paribas analysts maintain optimism for the technology sector, expecting second-quarter earnings to support continued momentum. However, the withdrawal of consistent inflows removes a key support mechanism for elevated valuations, making markets more vulnerable to negative catalysts.

The data suggests investors are tactically repositioning rather than abandoning equities entirely, reducing exposure to concentrated US megacap technology while seeking opportunities in other regions and maintaining selective tech exposure. This rotation indicates profit-taking after a strong rally rather than a fundamental shift to risk-off positioning.
