ETF Holdings Overlap

How much do two funds actually share? Weight-based overlap, shared positions, and what is unique to each side.

VOO/QQQVOO/SPYVTI/VOOSCHD/JEPIQQQ/XLKVXUS/VEAIWM/VTIVWO/IEMG

Shared holdings: 2 · PSOX has 21 tickered positions · SMH has 25

Overlap = sum of the smaller of the two weights for every shared holding. Holdings as of Oct 10, 2026. Positions without a clean ticker (bonds, cash, derivatives) are excluded from the match.
