TCI Fund Management Ltd

TCI Fund Management's $45.2 billion portfolio shrank by $8.5 billion in the first quarter, but the contraction was concentrated in a single exit rather than a broad retreat. The portfolio manager — one of the most recognizable names in activist value investing — reduced its Microsoft stake by more than 83% in a single quarter, cutting from 16.8 million shares to 2.7 million and shaving roughly $7.1 billion from a single line item. That one trade accounted for the substantial majority of the quarter-to-quarter book decline. Meanwhile, TCI kept adding to its core financial-data and payments franchise. Visa, Moody's, and S&P Global all saw net share increases in the first quarter despite falling prices — a meaningful signal that the manager saw each of these as cheap on a deteriorating-market auction. Alphabet was treated even more deliberately: TCI added to the existing GOOG position while simultaneously establishing a new, meaningful GOOGL class-A position of 2.4 million shares, a move that suggests a careful restructuring of the Google holding around the dual-class opportunity rather than a directional call on the stock. The profile that emerged is a tight ten-name portfolio dominated by industrial recovery (GE Aerospace at $13.5 billion), payments infrastructure (Visa at $9.2 billion), and the SIFMA-major data infrastructure axis (Moody's + S&P Global combined at $12.2 billion), with a small but structured Canadian Pacific Kansas City and Canadian National Railway freight-rail pair acting as the macro hedge. This is not a broad-market diversification play; TCI is a concentrated-activist vehicle that sizes its positions around expected catalyst events, and the MSFT exit strongly implies the manager no longer sees near-term upside in the software giant sufficient to justify the weight it had carried.
