Marshall Wace, LLP holds a diversified book of 2681 stocks worth $93.4B as of Q1 2026 (disclosed May 15, 2026, a ~45-day 13F lag). This quarter they opened Ste STR SPDR PT S&P 500 ETF and trimmed Ishares Core S&P 500 ETF. Their largest long position is Ishares Core S&P 500 ETF at 18% of the equity book. They also disclosed $5.2B 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 2014 would be +301% (+12.0%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +367.2%, a 66.2-point gap that is the cost of the ~45-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Marshall Wace, 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.
Top-heavy: diversified book
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.
