iShares S&P 500 ex S&P 100 ETF

The iShares S&P 500 ex S&P 100 ETF is an exchange-traded fund designed to offer targeted exposure to large-cap U.S. equities within the S&P 500 Index, specifically excluding the companies that comprise the S&P 100 Index. This ETF enables investors to access a broad segment of large-cap stocks, while intentionally omitting the largest names that often dominate headline indices. By focusing on the S&P 500 constituents outside the top 100, the fund provides a tool for investors aiming to manage concentration risk associated with mega-cap stocks and to diversify their U.S. equity allocations with greater precision. The iShares S&P 500 ex S&P 100 ETF is particularly relevant for portfolio builders and financial professionals seeking to complement existing mega-cap exposures or to implement more selective investment strategies within the U.S. large-cap sector. Operated by BlackRock, the fund is part of the broader iShares Build ETF lineup, which addresses growing demand for precise building blocks to navigate evolving equity market dynamics.
