AI Analysis · Q2 2026

Caledonia Investments' $856M Q1 2026 13F is a quietly run quality-compounder portfolio with 15 positions spread across technology, financial data, and business-services names. The manager added to Moody's — increasing the stake by 9.3% in shares even as the total value fell $4M — and increased Cintas by 25% in shares, both of which read as deliberate accumulation into quarter-end weakness. Philip Morris and Fortis were trimmed by roughly 4% and 10% in shares, respectively. There are no new positions and no outright sales this quarter; the portfolio is being actively managed within its existing mandate rather than rebuilt. The whaleScore of 75 reflects a $856M book of well-known compounders, not a speculative or high-turnover strategy.

Caledonia Investments' Q1 2026 13F is a list of businesses that generate high returns on capital and have pricing power — the kind of portfolio that performs best in risk-off environments and holds up through drawdowns. Texas Instruments, Microsoft, Fastenal, Charles Schwab, Moody's, Oracle, Cintas, and Paychex are all names with durable competitive advantages and high free-cash-flow conversion. The 15-position limit suggests the manager is deliberately concentrated within a quality mandate; there are no speculative biotech bets, no pre-IPO stakes, and no crypto exposure.
