DGRW tracks the WisdomTree U.S. Quality Dividend Growth Index, which selects US dividend-paying companies using quality and growth measures such as return on equity and return on assets, and weights them by the total dividends they pay rather than by market capitalization. The result is large weights in technology, healthcare, financials and consumer companies that pay large dividends. Dividend weighting makes the fund differ from cap-weighted funds, and it can be concentrated in the largest dividend payers.
