$100 Billion ETF Tsunami: SPY, VOO, IVV And More Drive Historic Equity Rebound Since March Low With Record $7.5 Billion Daily Inflows

Investors are flooding the U.S. stock market with capital at an unprecedented, record-breaking pace, with equity exchange-traded funds (ETFs) hitting fresh highs since the late March bottom.

Record-Breaking April

In a massive reversal of market sentiment, total U.S. equity ETF inflows have surpassed a staggering $100 billion since the market’s March 30th low.

Being the largest ETFs in the U.S., State Street SPDR S&P 500 ETF Trust (NYSE:SPY), Vanguard S&P 500 ETF (NYSE:VOO), and iShares Core S&P 500 ETF (NYSE:IVV)—are the primary vessels for this historic surge.

According to data from Strategas Asset Management shared by The Kobeissi Letter, average daily equity ETF inflows skyrocketed to a record $7.5 billion during the first three weeks of April.

To put this sudden influx into perspective, it represents a massive 153% increase compared to the March daily average of just $2.9 billion.

From Restraint To Re-Engagement

The stark contrast between the end of the first quarter and the beginning of the second quarter paints a vivid picture of renewed market confidence. As noted by Strategas in their recent flow analysis, “If March was about restraint, April is about re-engaging.”

For comparison, the full-year average for daily equity inflows in 2025 stood at $3.7 billion. The current April figures indicate that capital deployment is currently “running at more than DOUBLE last year’s pace,” according to market commentary from The Kobeissi Letter.

Pouring Capital Off The Sidelines

This aggressive pivot highlights a broader shift as both institutional and retail investors scramble for U.S. equity exposure following the spring pullback. The speed and sheer volume of the rebound suggest that market participants were sitting on substantial cash reserves, waiting for the optimal moment to strike.

As the flow data clearly indicates, that moment has arrived. Summing up the historic price action and subsequent capital rotation, market analysts observe that “investors are pouring more capital into equity funds than ever,” cementing this period as one of the most aggressive buying sprees in recent financial history.
