Questions
What does TCI Fund Management hold?
TCI Fund Management disclosed 11 positions worth $52.8B in the Q2 2026 13F filing. The largest is GE at 33.6% of the disclosed value. A 13F lists US-listed stock and options on it; short sales and cash are not in it.
What did TCI Fund Management buy and sell last quarter?
Comparing the Q2 2026 filing with the quarter before, the largest moves were selling out of MSFT, opening a position in MLM, opening a position in VMC and adding to GOOG. Changes are measured against the previous filing, not against trades, because a 13F does not disclose trades.
How current is this?
This is the Q2 2026 filing, covering positions held on Jun 30, 2026 and filed with the SEC on Aug 14, 2026. A 13F is due 45 days after the quarter ends, so the most recent filing is always at least six weeks behind the market, and the manager may have changed the book since.
