Why overlap matters
Funds are wrappers; stocks are what you own. Two "different" ETFs often hold the same mega-cap names, so buying both concentrates — not diversifies — your portfolio. OverlapCheck reads the official holdings files and does the arithmetic for you: exact shared holdings, weight-based overlap, and your true combined exposure.
