IGD overlap analysis compares holdings with other ETFs to identify shared positions. Overlapping holdings can lead to unintended concentration risk in a portfolio.

IGD portfolio overlap matters because owning multiple funds with the same underlying stocks reduces true diversification. With 516 holdings, IGD may share significant positions with broad-market funds.

IGD overlap tool lets you enter any other ETF ticker and see the exact overlap percentage and shared holdings. IGD tax-loss harvesting finds highly correlated but non-identical funds.
