All returns are total returns (dividends reinvested), through the latest price during the session. CAGR = compound annual growth rate. '—' means the fund's history doesn't span the horizon. A mutual fund's AUM is its whole fund's, every share class together (its SEC filing); an ETF's is its own. Returns run to Oct 30, 2026, the last month-end, as fund companies report a mutual fund's: a fund that pays monthly books each month's income on its last business day, so a return to a later day would leave that month's income out.

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: FNILX holdings · VOO holdings. Past performance does not predict future returns; not investment advice.
