Triodos Investment Management BV holds a diversified book of 50 reported positions worth $1.6B as of Q2 2026 (disclosed Jul 29, 2026, a ~29-day 13F lag). This quarter they opened Smurfit Westrock PLC and trimmed Taiwan Semiconductor-SP ADR. Their largest long position is Kla Corp at 6% of the reported non-option book. Cloning the disclosed picks since 2024 would be +18% (+9.5%/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 11.0 points over this window.
Growth of $10,000 cloning Triodos Investment Management BV's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~29 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
