TransDigm Group INC, looked up backwards: the 13F managers we track, every institution that filed a 13F, and the funds whose portfolios we scan, each from its own SEC filing. A 13F describes the quarter it names and is due 45 days after that quarter ends, so these holdings are at least six weeks old the day they become public. What filers reported, not a recommendation.

Common stock only: a fund’s puts and calls on TDG are not counted as holding it. We keep each fund’s 25 largest positions, so a manager holding TDG further down its 13F is not listed.
Every registered fund files its complete portfolio with the SEC. These weights come from those filings, so each one carries the period it describes. Holdings are quarterly and filed in arrears — the figures below are as of 2026-06-30 to 2026-07-31, not today.

Drawn from 38 large US equity funds we scan, not every fund in existence, so a missing fund means we do not scan it rather than that it holds none. Holdings are joined to tickers by issuer name, which does not resolve every position; what that misses is published.
