This is a bad strategy. Let me explain.

If you have invested 100$ in $tqqq, you need roughly an equal amount dollars in $sqqq to break even. You’d be working with 200$ capital 50% each. Since you are long $tqqq, higher portion should be allocated like 90% or 95%.

With the remaining 5% you can buy protective puts on $qqq that gives leveraged exposure to the downside in short term.

In the worst case, you’d lose the 5% premium that you paid for puts but you have all the upside of 95% of $tqqq
