Guggenheim Solar ETF (NYSEArca: TAN)
January Gain: 14%
Comment: TAN more than doubled last year and was 2013’s best non-leveraged ETF of any type making its double-digit gain to start 2014 all the more impressive. TAN has performed well to start the year despite significant exposure to China, making us wonder if emerging markets were even flat instead of plunging, how much would TAN be up this month?
