Quant hedge funds outpaced human managers in a volatile July

Renaissance Technologies led the charge, with its Renaissance Institutional Equities fund climbing 9.2% in July, effectively erasing losses from the first half of the year. The firm's Institutional Diversified Alpha fund also maintained momentum, adding 4.1% to reach a 14% return for 2026. Other major players followed suit: Two Sigma’s Absolute Return Enhanced fund grew 0.6%, while Paris-based Capital Fund Management saw its $12.4 billion Stratus fund gain 1.9%.

Graham Capital’s Tactical Trend strategy continued its aggressive year, rising 1.8% to reach a 23.7% year-to-date return. Conversely, London-based Qube experienced a minor setback, with its Torus strategy dipping 0.7%, though it maintains a strong 18% return for the year. These results highlight a widening divide in performance as human-run multistrategy firms struggled to navigate the same volatility. The disparity became particularly evident in the collapse of Leopold Aschenbrenner’s Situational Awareness, which plummeted 67% in July. The resulting portfolio fire sale benefited Ken Griffin’s Citadel, which secured a 14.2% gain in its equities fund, further distancing the industry’s top performers from the rest of the pack.
