SCHA provides access to 1,700+ small-cap stocks trading in the US exchange. The fund tracks a simple, market-cap weighted index intended to provide beta exposure to the market. Selection starts with the constituents of the broader Dow Jones index ranked by market capitalization in descending order. Constituents ranked at 2,000 and above are selected for the index. If the fund still does not have 1750 stocks, it adds the smallest non-constituents stocks by descending market cap until it reaches 1750 stocks. The index is reconstituted annually each September.
