NEW YORK ( TheStreet) -- Searching for income, investors have been pouring into exchange-traded funds that hold big dividend-paying stocks.A favorite choice is Vanguard High Dividend Yield ETF ( VYM), which yields 2.9%. But you can get more income with two ETFs that invest in smaller stocks: WisdomTree SmallCap Dividend ( DES), which yields 3.7%, and WisdomTree MidCap Dividend ( DON), with a yield of 3.2%. Besides solid dividends, the WisdomTree funds have also delivered strong total returns. During the past five years, the small-cap fund returned 8.9% annually, compared to 5.5% for the S&P 500 and 7.7% for iShares Russell 2000 ETF ( IWM). WisdomTree Midcap returned 9.4% annually, compared to 7.3% for iShares Russell Midcap ( IWR). Not many funds focus on small-cap dividend stocks. When they seek income, investors prefer funds that hold familiar mega-cap dividend payers, such as Exxon Mobil ( XOM) and Johnson & Johnson ( JNJ). Small-cap companies are often seen as more volatile and less likely to deliver stable income. But even though small stocks can be volatile, they have a long track record for generating compelling results. Many academic studies have shown that small stocks outdo large ones over the long term. Dividend-paying small stocks do especially well. From the end of 1984 through the first quarter of this year, the dividend-paying members of the Russell 2000 outdid the nondividend payers by 2.6 percentage points annually, says Adam Peck, portfolio manager of Heartland Value Plus ( HRTVX), a mutual fund that buys small-cap dividend stocks. Peck says that dividend stocks can be less volatile than nondividend payers. "Dividend payers tend to be more well-established companies with consistent cash flows," he says.
Because they must make regular cash payments to shareholders, dividend companies tend to be disciplined about how they manage their balance sheets, Peck says. When they are required to pay dividends, CEOs are less likely to take on debt or spend heavily on risky acquisitions. Jeremy Schwartz, WisdomTree's research director, says that average dividend stocks are more profitable. The stocks in the WisdomTree small-cap index have returns on equity of 7.5%, compared to 5.6% for the Russell 2000. "About 20% of the weight of the Russell 2000 is in unprofitable companies," says Schwartz. "Dividend payers tend to be more profitable."
