iShares U.S. Technology ETF(AMEX:IYW)

IYW offers broad exposure to the US technology segment, tracking a diversified, market-cap-weighted index. Cap-weighted exposure in this sector often translates to concentrated positions in tech giants. The indexs weight restraints, primarily, capping individual securities at 22.5% and capping all issuers individually exceeding 4.5% to a maximum of 45% are not unusual and still allow for plenty of single-name impact. The index pulls from a universe covering the top 95% of the market. The index is reconstituted annually with reviews quarterly. Prior to September 20, 2021, the fund tracked the Dow Jones U.S. Technology Capped Index.
