Trillium Asset Management, LLC holds a diversified book of 230 reported positions worth $3.3B as of Q2 2026 (disclosed Aug 11, 2026, a ~42-day 13F lag). This quarter they opened Okta Inc and trimmed Nvidia Corp. Their largest long position is Nvidia Corp at 7% of the reported non-option book. Cloning the disclosed picks since 2013 would be +245% (+10.1%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +283.3%, a 38.4-point gap that is the cost of the ~42-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Trillium Asset Management, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~42 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
