Hedge funds have been buying equities at the fastest pace ever recorded, purchasing a net $86 billion in stocks over the past five trading sessions as easing geopolitical tensions and a string of strong earnings reports triggered systematic, trend-following strategies to flip from short to long, according to Goldman Sachs prime brokerage. Goldman analysts estimate the funds could add another $70 billion if momentum continues.
The buying surge represents a dramatic reversal from the net short positioning that characterized hedge fund behavior during the height of the Iran-Hormuz crisis in late March and early April, when funds bet heavily against equities as oil prices spiked toward $120 per barrel. The recent de-escalation flipped the macro calculus for quantitative and macro strategies almost overnight.
CTA and Macro Funds Lead the Charge
Commodity trading advisors (CTAs)—systematic funds that mechanically follow price trends—and global macro funds drove the bulk of the buying. As equity indices broke back above key technical thresholds, trend signals flipped to positive, algorithmically triggering position builds across S&P 500, Nasdaq, and European equity futures.
"When CTAs flip, they flip hard," said Morgan Stanley's chief US equity strategist. "We're seeing mechanical buying that has very little to do with fundamental valuation and everything to do with momentum signals."
Retail Investors Join the Rally
Retail investor sentiment also improved sharply, with the AAII Bull-Bear survey showing its highest bullish reading in six weeks. Net equity fund inflows from retail channels totaled $8.3 billion this week—the strongest since January—suggesting the institutional buying surge is pulling in individual investors.
The Dow rose 869 points earlier in the week to recoup all of its Iran-war losses, though indexes have given back some ground as oil prices remain elevated and the geopolitical situation stays fluid. The S&P 500 closed Thursday at 7,108, down 0.41%, as investors awaited further clarity on the peace talks.
