13F stock ownership research

RESTAURANT BRANDS INTL INC (QSR) institutional holdings and quarterly fund activity

This reverse-ownership view starts with QSR and shows every matching position in SnowballHare's tracked 13F manager universe. It connects holder-level changes with four-quarter history and company research without presenting delayed filings as live ownership.

Deterministic analysis from filing data

How institutions moved in QSR this quarter

Institutional positioning in QSR is visible through the named holders. 3 active managers reported $1.7B in aggregate value. Pershing Square is the largest tracked holder. The sample is too small for a broad concentration reading.

Position changes show where the quarter differed from the prior filing. Duquesne Family Office made the largest measured share-count move at -62.4%. These filings describe quarter-end positions and do not confirm what managers held after the reporting date.

Looking back across quarters separates persistence from a single-period move. Holder count remains near the trailing average of 2.8. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.

The final cross-check is to compare QSR with similar company pages. Related ownership pages include AAPL, AXP, KO. Return to QSR stock research for financial statements, earnings, and company risks.
