US equity funds attracted fresh money in the week through September 30, extending a run of investor demand that has kept large-cap markets resilient despite pressure from high government-bond yields.
According to LSEG Lipper data reported by Reuters, investors made net purchases of $20.6 billion in US equity funds during the week. That followed $37.49 billion of inflows in the previous week. Large-cap equity funds accounted for most of the latest demand, attracting $19.33 billion, while multicap funds received $1.01 billion and small-cap funds drew $223 million. Mid-cap funds recorded outflows of $329 million.
The figures suggest that investors continue to favor companies perceived to have strong earnings visibility, balance-sheet capacity and exposure to artificial-intelligence spending. The Nasdaq Composite had recently reached record levels, while expectations for sustained demand for computing infrastructure supported the technology complex.
The allocation data also shows that the market’s enthusiasm is selective. Sector equity funds experienced net outflows of $4.1 billion, led by $3.79 billion withdrawn from technology funds and $738 million from industrial funds. That divergence may indicate that investors are concentrating exposure in broad large-cap vehicles rather than aggressively adding to narrower sector funds.
Bond flows provided a second important signal. US bond funds attracted $6.45 billion, their strongest weekly inflow in three weeks. Short-to-intermediate government and Treasury funds received $4.3 billion, while general domestic taxable fixed-income funds drew $4.02 billion. Money-market funds, by contrast, recorded $41.36 billion in outflows.
The combination points to a portfolio rotation rather than a simple flight from risk. Investors appear willing to maintain equity exposure while adding duration selectively and reducing cash holdings. That behavior can support markets when economic data are soft enough to limit additional rate increases but not weak enough to threaten corporate earnings.
For institutions, the key issue is whether AI-linked earnings growth can continue to justify equity valuations while the cost of capital remains elevated. Higher yields increase discount rates, raise financing costs and can challenge long-duration growth assets. At the same time, strong infrastructure demand may support revenues for selected chip, networking, software and data-center companies.
The latest fund-flow data therefore does not remove valuation or macroeconomic risk. It shows that, as of the week ending September 30, investors were still treating AI-driven earnings potential as powerful enough to offset concerns about bond-market volatility. That balance remains central to the direction of global portfolios in the final quarter of 2026.
