ETFs have a small management fee built into them. I don't concern myself with stuff like that as it will sidetrack you. You don't have to do anything about that. ETFs trade just like a stock. And now with Inverse ETFs you can trade these short ETFs in a registered retirement account as well. There are numerous short,double short and triple short ETFs. The triple short SPX ETF:SPXU is a nice one to trade. Most have high volume but not all. The Silver ETF is SLV and their is a double bull and double bear Silver ETF. The double bear ETF for Silver is ZSL. Here is a link to all the ETFs with Sectors and their ETFs, Commodities and their ETFs, Currencies and their ETFs, Fixed Income ETFs, Volatility ETFs and below that Internal breadth indicators all with charts. Also see at the top of the page the Education Bar with sub tabs for chart patterns with brief text plus short videos and a ton of other free stuff on this site that's usable.
