Boussard & Gavaudan Investment Management LLP holds a focused book of 84 reported positions worth $1.0B as of Q1 2026 (disclosed May 15, 2026, a ~45-day 13F lag). This quarter Sunbelt Rentals Holdings Inc first appears in 13F filings, a listing rather than a purchase; they opened Bridgebio Pharma Inc and trimmed Western Digital Corp. Their largest long position is Western Digital Corp at 18% of the reported non-option book. They also disclosed $279K in put options (a bearish bet) and $17.0M in call options (bullish), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2014 would be +1507% (+26.4%/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 1258.5 points over this window.
Growth of $10,000 cloning Boussard & Gavaudan Investment Management LLP'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.

13F filers disclose option positions at the market value of the underlying the contracts reference, not the premium paid. A put is a bearish bet (it gains if the stock falls); a call is bullish. “Underlying shares” is the share count the contracts control, not a share holding. These legs are excluded from the non-option book, weighting, concentration and sector figures above.
