QQQ vs XLK: ETF overlap
Holdings as of June 30, 2026 · SEC fund filings · QQQ source document · XLK source document
Overlap by weight: for each stock both funds hold, take the smaller of its two weights, then add those up. 58% means about 58 cents of every dollar in one fund is invested in the same companies, at the same size, as the other. The overlap level is PortLens's grouping of that figure, not an industry standard. What is ETF overlap?
