%%Theoretically, they may be good to a seasoned pro, but Murphy's Law tends to rule over ETFs and bear trading for me.
In a sideways= slop= chop=, better off in cash ETFs like SPY/QQQ/dividends............
I closed out something like SQQQ, about as liquid, today, fine.
BUT what you have to watch out for, even in a liquid inverse ETF as SQQQ; have to plan exits. Because time is not the bears friend, even in a bear market. I've made more in stuff like UPRO......... than SQQQ, but not today, as of noon / LOL.
So for me,position size it accordingly+ plan exits, if you want to try it................................................ Young traders blow up trading too BIG. I blew up an account by grinding one down/daytrading years ago.[Believe it or not, SQQQ pays a good dividend, but as IBD founder said, never buy something for just dividend]
You can see on a long term monthly chart of FAZ, for example why you have to plan for exits ,or stay out of that one, for example. NOT suitable for all investors.
