About MASKX

The iShares Russell 2000 Small-Cap Index Fund Institutional Shares is an index mutual fund designed to closely track the performance of the Russell 2000 Index, which represents approximately 2,000 small-capitalization companies in the U.S. equity market. Its primary purpose is to provide investors with broad, efficient exposure to the small-cap segment, capturing the growth and diversification potential that smaller companies can offer. The fund is structured as a feeder fund, investing substantially all of its assets in a corresponding master portfolio with the same investment objectives and strategies. It typically holds nearly two thousand securities across diverse sectors, reflecting the composition of its benchmark index. This approach makes the fund a significant tool for institutional investors seeking to gain or maintain small-cap equity exposure within a portfolio allocation. With a low net expense ratio and a process focused on index replication, the fund emphasizes cost efficiency and liquidity. Its role in the financial market is to serve as a core or satellite holding for diversification, risk management, or to target specific market capitalization segments within investment strategies.
