Simplex Trading, LLC holds a diversified book of 2613 stocks worth $3.2B as of Q1 2026 (disclosed May 14, 2026, a ~44-day 13F lag). This quarter they opened Amazon.com Inc and trimmed Ishares Semiconductor ETF. Their largest long position is Nvidia Corp at 8% of the equity book. They also disclosed $76.9B in put options (a bearish bet) and $69.0B in call options (bullish), shown separately below and excluded from the equity book. Cloning the disclosed picks since 2015 would be +234% (+11.1%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +254.3%, a 20.7-point gap that is the cost of the ~44-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Simplex Trading, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~44 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.
