• Institutional clients were net buyers of U.S. equities last week, pouring $4.3 billion into ETFs—the largest inflow since December 2022
  • Hedge funds and retail investors sold equities overall, with institutions emerging as the sole net buyers
  • Sector flows showed a defensive tilt with money moving out of Tech and Communication Services and into Staples and Health Care

Institutional investors stepped firmly into the U.S. equity market last week, deploying capital as others retreated in a notable shift in market dynamics. According to Bank of America's latest client flow data, institutional clients were net buyers even as they sold $2.6 billion in individual stocks, with the entire net buying activity driven by massive ETF inflows.

The $4.3 billion that poured into exchange-traded funds marked the largest institutional ETF inflow since December 2022, suggesting large asset managers and pension funds are using the vehicle for quick, diversified exposure during market dips. This contrasts sharply with the behavior of other investor groups—both hedge funds and retail investors were net sellers during the same period.

"We're seeing institutions replace retail investors as the primary dip buyers this year," said a strategist familiar with the flows, who asked not to be identified discussing client data. "The retail momentum that characterized previous rebounds appears to be fading."

Sector-level flows revealed a distinctly defensive posture among market participants. Money moved out of growth-oriented sectors like Technology and Communication Services, while finding its way into more defensive areas such as Consumer Staples and Health Care. This rotation suggests institutional investors are positioning for potential economic uncertainty while still maintaining equity exposure.

The shift comes as corporate buybacks remain below typical seasonal levels, removing what has traditionally been another key source of market support. With companies pulling back on share repurchases and retail investors retreating, institutions have increasingly filled the void.

Bank of America representatives declined to comment beyond the published data when reached Thursday afternoon. The flows tracking is part of the bank's regular weekly analysis of client trading activity across its extensive institutional and retail platforms.

Market participants will be watching closely to see if this institutional buying pattern persists in the coming weeks, particularly if volatility increases. The defensive sector rotation indicates that while institutions are willing to buy dips, they're doing so with caution.
