Best Exchange-Traded Fund

Guggenheim Solar ETF


Sporting the ticker TAN, Guggenheim Solar ETF invests in 27 solar power companies from the U.S., China and elsewhere. Solar stocks crashed in 2011 when oversupply led to a 52 percent drop in solar panel prices. Prices fell further in 2012 but rebounded this year as the supply glut diminished. That reversal helped triple the Bloomberg Solar Global Large Solar Energy Index, an index of solar manufacturers that had at one point lost 87 percent of its value.
