So — nearly identical. Should you hold both?
IVV and VT hold nearly the same stocks in nearly the same proportions — owning both is largely redundant. If you already hold IVV, adding VT mostly increases your bet on the names they share rather than spreading it — a 50/50 blend still behaves like only ~86 equal positions, with the top 10 alone at 29% and the Magnificent Seven at 25%.
