Zweig-DiMenna Associates LLC holds a diversified book of 70 stocks worth $1.1B as of Q3 2026 (disclosed Aug 13, 2026, a ~0-day 13F lag). This quarter they opened Planet Labs PBC and trimmed Amazon.com Inc. Their largest long position is Sandisk Corp at 7% of the equity book. Cloning the disclosed picks since 2025 would be +29% (+37.9%/yr). That is a simulation of the disclosed long book, not audited returns.
Growth of $10,000 cloning Zweig-DiMenna Associates LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~0 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.
