The fund delivers one of the strongest offerings in the US small-cap segment. It tracks the S&P SmallCap 600 Index - a broad basket of US small-cap stocks containing the 901st through the 1500th securities pulled from the S&P Total Market Index. With its fixed 600 constituents, the fund provides a purer exposure to small-caps as it excludes most midcap securities. Selected securities are weighted by market-cap and rebalanced quarterly. Overall, XSMC captures the US small-cap space well and favors investors seeking exposure to the long-term growth of smaller companies.
