AQR Arbitrage LLC holds a diversified book of 556 stocks worth $6.1B as of Q1 2026 (disclosed May 15, 2026, a ~45-day 13F lag). This quarter they opened Penumbra Inc and trimmed On Semiconductor Corp. Their largest long position is Electronic Arts Inc at 2% of the equity book. Cloning the disclosed picks since 2015 would be +144% (+8.2%/yr). That is a simulation of the disclosed long book, not audited returns.
Following at the filing date actually beat the quarter-end book by 52.5 points over this window.
Growth of $10,000 cloning AQR Arbitrage LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~45 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.
