QQQJ concentrates its portfolio to 100 largest companies by market cap that are next-generation constituents of the NASDAQ-100 Index. As such, securities must meet the existing NASDAQ-100 index eligibility criteria. QQQJ reflects companies from all major sectors, except financial firms as classified under the ICB Industry Classification Benchmark. Eligible security types are traded stocks, tracking stocks, shares of beneficial interest, limited partnership interests, and ADRs. Holdings are weighted using a methodology that is a hybrid of equal and market-cap weighting. Under this methodology, each issuer is capped at 4% weight. The index is rebalanced quarterly and reconstituted annually.
