Institutions Propel Return of Single-Stock Buying, BofA Data Shows

Bank of America’s weekly client flow data shows institutional investors were the primary source of equity purchases last week, driving $2.7 billion of inflows into individual stocks - the first weekly inflow after a three-week run of selling. At the same time, equity ETFs experienced $0.8 billion of outflows. Year-to-date patterns show clients remain net sellers of single stocks while buying ETFs overall.

Key Points

  • Institutional investors were the primary drivers of last week’s equity buying, leading to $2.7 billion of inflows into individual stocks - the first weekly inflow in four weeks.
  • Equity ETFs recorded $0.8 billion of outflows after four consecutive weeks of inflows; year-to-date, clients are net sellers of single stocks by about $14 billion and net buyers of equity ETFs by roughly $6 billion.
  • Flows were concentrated in large-cap names and in seven sectors, notably Communication Services and Technology; small and micro-cap stocks saw outflows for a fifth straight week.

Institutional demand returned to the forefront of equity market activity last week, according to Bank of America’s weekly client flow data, lifting inflows into individual stocks after a short pause. The bank recorded $2.7 billion of net flows into single stocks, marking the first positive weekly total for direct stock purchases in four weeks.

Exchange-traded funds focused on equities moved in the opposite direction, with $0.8 billion of outflows, ending a four-week stretch of ETF inflows.

Examining year-to-date positioning, Bank of America notes that clients have been net sellers of individual equities by about $14 billion while purchasing roughly $6 billion of equity ETFs. That contrast underscores a broader preference for pooled equity exposure so far this year, even as last week tilted toward direct-stock buying.


Who was buying and who was selling

BofA strategist Jill Carey Hall attributed last week’s buying largely to institutional participants. As she wrote, "Buying was driven by institutional clients (biggest inflows since late Nov.) following two weeks of selling." Private clients also added to positions, remaining net buyers and purchasing equities in seven of the past eight weeks. Hedge funds, by contrast, registered net sales for a second consecutive week.


Market-cap and sector patterns

The flows were concentrated in larger-cap stocks. When combining activity in both individual stocks and ETFs, large-cap equities were the only market-cap segment to record inflows, reversing two prior weeks of outflows. Small and micro-cap names continued to see money exit, registering outflows for a fifth straight week. Bank of America noted the rolling four-week average for flows into small and micro-cap segments is now the most negative on record, a shift from the heavy inflows those segments experienced late last year.

By industry, clients bought into seven of the eleven major sectors, led by Communication Services and Technology. Communication Services has attracted inflows since late December and has drawn the largest cumulative flows so far this year. Energy stocks saw buying for the first time in five weeks, although those purchases occurred before the latest Middle East conflict escalated.

On the selling side, Financials and Consumer Discretionary posted the largest outflows. Financials have now experienced eight straight weeks of outflows, while Consumer Discretionary has seen selling for five consecutive weeks.


These flow dynamics highlight a bifurcated market in which institutional money can shift direction on short notice, while smaller-cap segments and some cyclical sectors continue to face sustained withdrawals. Bank of America’s weekly data provides a snapshot of how different client groups are positioning across market caps and sectors, but the bank’s figures also reflect ongoing variation between direct-stock purchases and ETF-based exposure.

Risks

  • Small and micro-cap segments face ongoing outflows, with the rolling four-week average now the most negative on record - this continued pressure could affect liquidity and price stability in smaller equities.
  • Financials and Consumer Discretionary have experienced prolonged selling - eight straight weeks and five consecutive weeks of outflows respectively - creating sector-specific downside risk for those industries.
  • Momentum in ETF outflows versus single-stock buying may shift quickly; while institutions drove single-stock inflows last week, the opposite trend in ETFs suggests changing demand patterns that could reverse market leadership.
