Guggenheim Spin-Off ETF (NYSEArca: CSD)
YTD Gain: 40%
Comment: CSD is one of the most popular ETFs on this list. Sure, CSD stands as proof that some spin-offs perform well, but CSD has also benefited this year from a bias toward small- and mid-cap names. The average market cap of the ETFs’s 25 holdings is $6.4 billion, according to Guggenheim data.
