Poking holes in TQQQ
I've seen thisfloating around this board for a bit now, and after looking at it back to '99 (using QQQ *3 daily returns as a proxy for the days before it actually existed), I'm now becoming a believer. To the skeptics, if this thing can survive 3 of the worst crashes in history, what are the real downsides assuming you personally never have to sell? Could you theoretically see a run on the ETF even if on paper it's not bankrupt that would force it to go bankrupt? Is counterparty risk a significant factor that was somehow not an issue in the 2020 crash? What other risks am I not seeing that make this a terrible investment?
