IYJ is passively managed to deliver a capped, vanilla exposure to the US industrials sector. The index invests in all industrial companies, as classified by the ICB framework, in the Russell 1000a market cap-weighted index of the largest 1,000 US stocks. Regulatory capping targets are applied at each quarterly rebalance such that single issuer weights are capped at 15% and aggregate weight of all companies with weight exceeding 4.5% is capped at 22.5%. Instead of replicating the index, IYJ uses representative sampling to track the index. Prior to September 20, 2021, the fund tracked the Dow Jones U.S. Industrials Index.
