Best: Guggenheim Solar ETF
Really, the Guggenheim Solar ETF (TAN) had nowhere to go but up. Even after gaining more than 50% so far in 2013, TAN remains 91% off its opening price at launch in April 2008.
But the picture for solar has been improving this year. Demand continues to head higher in the U.S., China and Japan, and while prices for panels and other components remain low, costs have dropped as well, helping buoy the manufacturers.
TAN itself has been lifted by the strong performances of not only SCTY, but silicon wafer manufacturer SunEdison (SUNE, +154%) — formerly MEMC Electronic Materials — and photovoltaic solar module maker First Solar (FSLR, +45%).
