AQR CAPITAL MANAGEMENT LLC

AQR Capital Management's 13F book grew to $218.4B in Q1 2026 from $190.6B, and its defining feature is breadth: more than 20,800 positions with no single name above 2.5%. Nvidia (2.50%), Microsoft (1.69%), and Apple (1.66%) sit at the top of an unusually flat distribution characteristic of a systematic, factor-driven strategy. The quarter's builds favored power and infrastructure — GE Vernova (+$545M) and Comfort Systems (+$538M) — alongside additions to Microsoft (+$654M) and Nvidia (+$570M). New positions opened in Costco, Verisign, Western Digital, Eli Lilly, and Travelers; Palantir, Roblox, Zoom, and Expedia were trimmed or sold.
