So — nearly identical. Should you hold both?
IVV and VV hold nearly the same stocks in nearly the same proportions — owning both is largely redundant. If you already hold IVV, adding VV mostly increases your bet on the names they share rather than spreading it — a 50/50 blend still behaves like only ~50 equal positions, with the top 10 alone at 38% and the Magnificent Seven at 33%.
Holdings as of — IVV: Jun 30, 2026 (iShares (BlackRock)); VV: May 31, 2026 (Vanguard). Refreshed monthly. Overlap is measured across each fund’s largest holdings (top 50); the diffuse long tail barely moves the math.
