IYC tracks an index of US companies in the consumer discretionary industry, which are companies most sensitive to economic cycles and cyclical purchasing habits. Eligible companies include those that manufacture household durable goods, apparel, electronics, and other non-essential items, and those that offer services like hotels, restaurants, retail/e-retail, entertainment and advertising. IYC uses market-cap to select and weight its constituents, and individual securities within the portfolio are capped at 15% at each quarterly rebalance. Aggregate weight of all companies with weight exceeding 4.5% is capped at 22.5%. Prior to September 20, 2021, the fund tracked the Dow Jones U.S. Consumer Services Capped Index and was named iShares U.S. Consumer Services ETF.
