What are the ETFs with the highest yield?

As of March 2015, the highest-yielding exchange-traded fund is the UBS Etracs 2x Leveraged Long Alerian MLP Infrastructure Index at 13.18 percent, according to Dividend.com. The ETF with the second-highest yield is the UBS Etracs Monthly Pay 2x Leveraged Dow Jones Select Dividend Index at 10.53 percent.

Etracs are exchange-traded notes, or ETNs, in ETFs pegged to the Alerian Master-Limited Partnership Infrastructure Index and to the Dow Jones Select Dividend Index, reports UBS. The Alerian MLP Infrastructure Index is a composite of master-limited partnerships involving companies that transport, store and process energy commodities, explains Alerian. The Dow Jones Select Dividend Index tracks high-performing companies on the Dow Jones, states ETF Daily News. These funds are traded on the New York Stock Exchange as MLPL and DVYL.

Exchange-traded funds are a type of open-ended investment company, according to the U.S. Securities and Exchange Commission. ETFs sell their shares in large blocks called creation units, which investors purchase with securities similar to those in the fund instead of cash. They may resell the shares individually on the stock market or redeem them for securities in the ETF portfolio. Leveraged ETFs, such as Etracs, may provide greater yields, but they come with greater risks, explains ETF Daily News.
