Low yields on Treasuries and high-quality bonds are pushing income investors to take on more risk. Even with a recent rise in yields, the yield on 10-year Treasuries is still only about 1.8% and that just isn't getting the job done for some. One area where people are looking for yield is dividend-paying stocks, and a popular way to own stocks is through exchange-traded funds or ETFs.

The website ETFdb lists 52 funds with a dividend investment style. This review will profile five funds with dividend growth as one criterion for the indexes they track. Four of the funds focus on U.S. companies, while one looks outside the U.S.

The yields on these funds all top 10-year Treasuries, and most of them give long-term, high-grade corporate bond yields a good run. In addition, the indexes they track offer a solid potential for regular increases in the payout from the stocks these funds hold.

Solid potential for increases is fine, but have the funds met that potential? In general, the history isn't too bad. Despite dips in payouts during the financial crisis in 2008-09, the funds have seen their dividends bounce off their worst levels in recent years.

I'm a big fan of dividend growth investing and am making an outperform CAPScall on the Vanguard Dividend Appreciation fund. Even though it has the lowest current yield of these five funds, it's been the most successful at raising payouts and has the lowest expense ratio.

Shifting from bonds to stocks or stock-based funds for income doesn't come without risk.  Investors considering the move should have a long time horizon and take a good look at price charts that cover 2008-2009. They aren't pretty. That said, dividend checks spend just as well as bond coupon payments and can work out well for investors who understand and can accept the risks of owning stocks.
