TAN’s smaller rival, the $23.2 million Market Vectors Solar Energy ETF (NYSEArca: KWT), is down 6% today. The intraday performance gap between TAN and KWT is explained by the latter’s 4.3% weight to GT Advanced, making it the ETF’s eighth-largest holding, according to Market Vectors data.

News of the GT Advanced bankruptcy has rendered KWT and TAN two of Monday’s worst-performing non-leveraged ETFs.
