So — heavily overlapping. Should you hold both?
VGT and VOOG share most of their weight in the same names; the second fund adds only modest differentiation. If you already hold VGT, adding VOOG mostly increases your bet on the names they share rather than spreading it — a 50/50 blend still behaves like only ~21 equal positions, with the top 10 alone at 54% and the Magnificent Seven at 43%.
