DGS holds emerging market-companies that have paid dividends over the past calendar year and weights them based on the size of dividends paid. DGS only includes stocks that are in the bottom 10% of total market-cap of the WisdomTree Emerging Markets Dividend Index. The resulting portfolio tilts large and makes some big country bets. It's also a fairly concentrated fund, though sector exposures tend to be roughly market-like. The index is reconstituted and rebalanced annually.
