Investment Management Corp of Ontario holds a diversified book of 657 reported positions worth $7.9B as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). This quarter Space Exploration Techn-CL A first appears in 13F filings (one of 4 new listings in the book), a listing rather than a purchase; they opened Honeywell International Inc and trimmed Nvidia Corp. Their largest long position is Nvidia Corp at 6% of the reported non-option book. Cloning the disclosed picks since 2021 would be +96% (+12.9%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +121.9%, a 25.5-point gap that is the cost of the ~45-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Investment Management Corp of Ontario'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.
