Understanding VOO’s concentration
VOO is weighted by market capitalization, meaning larger companies make up a larger share of the fund automatically — Vanguard doesn’t set these weights directly. Because a handful of mega-cap technology companies currently dominate U.S. market value, VOO’s performance is more tied to those specific companies than the “500 companies” framing might suggest. This isn’t unique to VOO — any S&P 500 fund, including SPY or IVV, shares the same concentration by definition.
