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

RA portfolio overlap matters because owning multiple funds with the same underlying stocks reduces true diversification. With 645 holdings, RA may share significant positions with broad-market funds.

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