Buying SQQQ for a hair over $16. 52-week low is 15.89, lol, this thing does get decay and you can see it, after a month with QQQ -20%, the ETF is just barely holding February price, but it traded for $48 on 23 March. We gonna get another slam-down soon so this is a simple strategy. Don't hold this thing long-term, just a week or two at most, else decay will eat you alive. It's a futures ETF, lol.
IMO these ETFs trade like LEAPS options, and may even cost less now, lol.
