Unlike some other popular dividend ETFs, DES does not weigh its components based on length of dividend increase streaks or yield. Rather, the WisdomTree SmallCap Dividend Index, the underlying index for DES, focuses on the “aggregate cash dividends each component company is projected to pay in the coming year, based on the most recently declared dividend per share,” according to WisdomTree.
