We wade through the swamp of esoteric and risky new exchange-traded funds to find four worth your while. Thinkstock By Kaitlin Pitsker, Associate Editor From Kiplinger's Personal Finance, April 2015 Nearly 200 new exchange-traded products debuted last year, many of them ill-advised.

Ford O’Neil manages both, and both charge 0.45% annually to cover expenses. The ETF can be traded commission-free at Fidelity’s brokerage arm and yields 3.2% (yields are as of early February). If you’re a dividend hound, consider iShares Core Dividend Growth ETF (DGRO) and ALPS Emerging Sector Dividend Dogs ETF (EDOG). The iShares ETF tracks an index of U.S. firms that have regularly hiked their payouts. It boasts a slim 0.12% in expense fees and yields 2.4%. Dogs digs for bargains by tracking an index of dividend-paying laggards across 10 sectors of emerging-markets stocks. It yields 5.5% and carries an expense ratio of 0.60%. It may seem gimmicky, but USCF Stock Split ETF (TOFR), which tracks an index of firms that have recently split their shares, isn’t as far-fetched as it seems. Although splits have no impact on the value of your investment or of a stock’s key ratios, they’re generally seen as a sign that a company expects good times ahead. Annual fees: 0.55%.
