iShares MSCI USA Equal Weighted ETF

EUSA provides a different approach to US large- and midcap firms. The fund includes the same stocks as its parent index, the MSCI USA Index, but applies equal weighting at each quarterly rebalance, effectively removing the influence of each constituents current price and preventing overweighting to larger firms. The quarterly rebalance starts in February. Prior to Sep. 1, 2015, the fund tracked MSCI USA Index, a market-cap-weighted index of the same constituents.
