Investors may not know what to invest in to tap into that sector or which stocks are best, and that's where an ETF can help. If you are bullish on alternative energy, in particular, hydrogen, then Defiance Next Gen H2 ETF (NYSEArca:HDRO) is a fund you will want to check out.
And with U.S. President Joe Biden pushing greener initiatives, this ETF could become a hot buy under his administration. With 25 holdings, this isn't a large fund.
