This ETF offers exposure to small cap U.S. stocks, an asset class that is included in most long-term portfolios and can be useful for tactical traders looking to implement a tilt towards riskier securities. DES is one of dozens of options for small cap exposure through ETFs, and is unique because of the weighting methodology employed. The related benchmark is dividend-weighted, determining components companies and individual allocations based on cash dividends paid. That methodology has the effect of enhancing current returns from the equity side of a portfolio, and may also be appealing for those looking to utilize alternatives to market cap-weighting (which has a tendency to overweight overvalued stocks, and underweight undervalued companies). DES is slightly more expensive than some of the cap-weighted alternatives, but investors who believe the dividend-weighting approach has the potential to add value over the long run will find the expense differentials to be minimal. This fund may be worth considering as an alternative to products such as IWM and IJR.
