Compiled from public SEC 13F-HR filings for a sample of 64 tracked institutions — NOT the whole market. 13F covers long US-listed equity only (no shorts, derivatives, or non-US holdings) and lags ~45 days. Net flow is estimated from share changes × current-quarter price. Institutional-behavior observation, not investment advice.
