XRT uses equal-weighting rather than market-cap-weighting to make radical differences in exposure and performance than its peers. The effect of equal weighting is keener than some other equal-weighted funds because it draws retail stocks, as defined by GICS, from the broad S&P Total Market Index that include stocks of any capitalization. The result, XRT has an order of magnitude in greater small- and micro-cap exposure. The fund holds retail companies that stretch across multiple sub-industries that include apparel, automotive, computers and electronics, department stores, drugs, food, general merchandise stores, hypermarkets and super centers, internet and direct marketing retail, and specialty stores. The index is rebalanced quarterly.
