BlackRock Launches Industry’s First S&P 500 ex Top 100 ETF for More Precise U.S. Large-cap Exposure

Complements the iShares S&P 100 ETF (OEF) to adjust exposure to S&P 500 companies

NEW YORK--(BUSINESS WIRE)--Today, BlackRock launched the iShares S&P 500 ex Top 100 ETF (NYSE:XOEF), expanding its iShares Build ETF toolkit, which enables investors to manage their U.S. equity exposure with precise building blocks. XOEF seeks to track the investment results of an index composed of the large-cap U.S. equities within the S&P 500 Index, excluding those in the S&P 100 Index.

The ETF offers investors a new way to target segments of the largest U.S. companies within the S&P 500 Index and to diversify their portfolios. Over the past two decades, the rise of mega-cap stocks has significantly reshaped the U.S. equity landscape, leading to indices with increasingly concentrated weightings in the largest names and greater dispersion within U.S. equity large-cap performance.¹

“Today’s market environment requires investors to be more intentional in managing mega-cap exposure within portfolios,” says Jay Jacobs, U.S. Head of Equity ETFs at BlackRock. "XOEF provides investors a new lever for managing mega-cap concentration with greater precision.”

XOEF is designed to complement existing mega-cap exposures, such as the iShares S&P 100 ETF (OEF), by offering targeted access to the remaining large-cap segment of the S&P 500 Index. This differentiated approach enables investors, including model builders and financial advisors, to take more selective positions and helps enhance diversification in portfolios.

BlackRock manages over $22 billion in assets across the iShares Build ETFs, reflecting growing investor demand for precision building blocks to manage equity exposure.²
