GSEW tracks an index that consists of around 500 US large-cap stocks, weighted equally. The promise of equal weighting is rules-based contrarianism, the fund sells winners and buys losers at each monthly rebalance. Equal weighting also boosts the weight of smaller firms within the large-cap space, resulting in slightly higher risk and return over the long run. On the other hand, the fund`s reduced concentration lowers single-name blow-up risk. Unlike some competitors, the fund doesn`t weight its holdings equally by sector. In addition, GSEW`s monthly rebalancing creates opportunities for slippage, be sure to check the fund`s tracking statistics for a picture of real world holding costs. The Index is reconstituted on a semi-annual basis starting each May.
