Thompson Investment Management, Inc. holds a diversified book of 504 reported positions worth $871.6M as of Q2 2026 (disclosed Jul 13, 2026, a ~13-day 13F lag). This quarter Fedex Freight Holding Co first appears in 13F filings (one of 3 new listings in the book), a listing rather than a purchase; they opened Workday Inc-Class A and trimmed Alphabet Inc-CL A. Their largest long position is Alphabet Inc-CL A at 5% of the reported non-option book. Cloning the disclosed picks since 2024 would be +40% (+19.4%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +41.7%, a 1.7-point gap that is the cost of the ~13-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Thompson Investment Management, Inc.'s disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~13 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
