Institutions Drive US Equity Demand as Buybacks Turn Positive Year-Over-Year, BofA Says

Bank of America data shows institutional buying across market caps and a rebound in corporate buybacks for the first time since early 2025

By Jordan Park

Bank of America’s weekly client flow report shows institutional investors were the primary buyers of U.S. equities last week, while corporate share repurchases rose on a year-over-year basis for the first time since early 2025. Single-stock purchases and equity ETF inflows expanded, with sector-level activity concentrated in Industrials, Real Estate and Energy.

Institutions Drive US Equity Demand as Buybacks Turn Positive Year-Over-Year, BofA Says

Key Points

  • Institutional clients were net buyers of equities for a fifth consecutive week, driving market inflows.
  • Corporate buybacks rose 44% year-over-year on a four-week average, the first annual increase since early 2025, but remain below historical norms relative to market cap.
  • Sector flows were uneven: Industrials, Real Estate and Energy saw the largest inflows, while Health Care, Consumer Staples and Communication Services experienced outflows.

Institutional demand powered net buying in U.S. equities over the last week, according to Bank of America’s weekly client flows, with corporate buybacks moving back into positive territory on a year-over-year basis for the first time since early 2025.

BofA clients were net purchasers of single stocks for the first time in three weeks, adding $1.1 billion, while equity exchange-traded funds attracted $2.2 billion of inflows, marking a tenth consecutive week of ETF buying.

Institutional clients were the main source of demand, sustaining a streak of five straight weeks of net purchases of equities. Hedge funds reversed course from the prior week and became net sellers, and retail investors also reduced positions for the second week in a row.

"Clients bought equities across all size segments," said BofA strategist Jill Carey Hall.

On the corporate side, the four-week average of buybacks by corporate clients increased 44% year-over-year, representing the first such annual rise since early 2025. Despite that improvement relative to a year ago, buyback activity eased slightly on a week-over-week basis and continues to run below its long-term average when measured as a percentage of market capitalization.

The trailing 52-week ratio of buybacks to market cap is at its weakest level since late 2023. The slowdown has been most evident in Technology, while Discretionary, Financials and Energy have registered year-to-date pickup in repurchase activity.

Sector flows showed buying across seven of eleven sectors, led by Industrials. Real Estate and Energy recorded the next-largest inflows, with Real Estate extending its buying streak to five consecutive weeks. By contrast, Health Care experienced the largest outflows, followed by Consumer Staples. Communication Services registered outflows for a fourth consecutive week. Technology registered only muted inflows after two weeks of net selling.

Hall reiterated the dominance of institutional demand: "Buying was driven by institutional clients, who have now bought equities for 5 straight weeks."

Within ETFs, investors favored Growth and Blend strategies, while Value funds moved into outflows for the first time in four weeks. Discretionary-focused ETFs drew their largest inflows since January 2025.

ETF purchases were broad across market-cap categories, with inflows into large-cap, small-cap and broad-market funds. Mid-cap ETFs, however, saw modest outflows. At the sector ETF level, Financials led the outflows, followed by Industrials.


This weekly snapshot from BofA highlights a continuation of institutional accumulation of U.S. equities and a tentative recovery in corporate repurchases on an annual basis. While buybacks have improved compared with a year ago, their pace relative to market capitalization remains subdued and the trailing 52-week metrics are at multi-year lows, signaling uneven support across sectors.

Risks

  • Buybacks remain below long-term averages as a share of market cap, signaling that corporate repurchases may provide limited support to equity valuations - this particularly affects Technology where the slowdown has been most pronounced.
  • Hedge fund selling and continued retail outflows could counterbalance institutional buying in short windows, introducing volatility across market-cap segments and sectors such as Financials and Industrials.
  • ETF flows showed value strategies moving into outflows and modest mid-cap ETF outflows, which could pressure mid-cap liquidity and performance relative to large- and small-cap segments.
