Methodology#

Returns are total returns (dividends reinvested) from daily adjusted closes. Holdings, overlap, sector weights and flows derive from each fund's public SEC filings (Form N-PORT), anchored on the latest filing and rolled forward daily by price moves. Overlap is the sum of the smaller weight across shared holdings. See each fund's full holdings: VOO holdings · SPY holdings. Past performance does not predict future returns; not investment advice.
