One River Asset Management, LLC holds a concentrated book of 53 reported positions worth $20.8M as of Q2 2026 (disclosed Jul 28, 2026, a ~28-day 13F lag). This quarter they opened SS SPDR S&P 500 ETF Trust-US and trimmed Microsoft Corp. Their largest long position is SS SPDR S&P 500 ETF Trust-US at 46% of the reported non-option book. They also disclosed $132.9M in put options (a bearish bet) and $156.1M in call options (bullish), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2024 would be +27% (+13.6%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +31.5%, a 4.9-point gap that is the cost of the ~28-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning One River Asset Management, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~28 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.
