Institutional Ownership and Flows

13F holdings aggregated by ticker and by manager, with quarter-over-quarter changes, plus fund and ETF ownership. Powerful, and only if the filing's limits are understood.

This guide is part of Analysis Tools Only.

What is in this guide

  • Everything here derives from Form 13F filings, which are 45 days lagged and long-only.
  • Top holders shows who owns it; changes shows what moved last quarter.
  • Hedge fund, ETF and mutual fund ownership are broken out separately.
  • Aggregate change across filers is far more robust than any single manager's.
  • Ownership concentration is a structural fact with correlation consequences.
