SPMO's AUM Surges Amid Strong ETF Inflows
The Invesco S&P 500 Momentum ETF (ticker: SPMO) experienced a significant surge in assets under management, with net inflows of $6.21 billion and an impressive 21.97% increase in AUM as of September 19, 2026. This performance placed it second on the list of top ETF creations for the day behind only the iShares Core S&P 500 ETF (IVV). The momentum strategy appears to be gaining traction among investors seeking exposure to high-performing stocks within the S&P 500 index. The broader market saw strong inflows into U.S. equity ETFs, with total net flows reaching $48.55 billion and representing a significant portion of overall AUM in that category (0.5%). In contrast, international equity funds also attracted notable capital, though at a lower rate compared to domestic offerings. Meanwhile, several popular ETFs such as the iShares Russell 2000 ETF (IWM) faced redemptions totaling $1.64 billion and saw its AUM decline by -2.12%. This highlights shifting investor preferences toward momentum strategies over traditional small-cap equity exposure.
