iShares Total U.S. Stock Market Index Fund Investor A Shares 

This fund aims to replicate the investment performance of the Russell 3000® Index, a widely recognized benchmark that gauges the overall health of the United States stock market. The underlying index is structured as a float-adjusted, market capitalization-weighted aggregation of the largest publicly traded companies based within the U.S. and its associated territories. To fulfill its mandate, the fund typically commits a minimum of 90% of its total assets, inclusive of any borrowed capital designated for investment, directly into the constituent securities of this benchmark index.
