Maven Securities LTD holds a focused book of 164 stocks worth $1.7B as of Q1 2026 (disclosed May 15, 2026, a ~45-day 13F lag). This quarter they opened State STR SPDR S&P 500 Et and trimmed Invesco QQQ Trust Series 1. Their largest long position is State STR SPDR S&P 500 Et at 13% of the equity book. They also disclosed $1.7B in put options (a bearish bet) and $1.8B in call options (bullish), shown separately below and excluded from the equity book. Cloning the disclosed picks since 2017 would be +204% (+12.4%/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 108.7 points over this window.
Growth of $10,000 cloning Maven Securities LTD'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.
Top-heavy: focused book
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.

These legs are excluded from the equity book, weighting, concentration and sector figures above. Showing the largest 25 of 239 option legs.
