OP may be inactive, but Direxion 3x S&P500 (SPXL) opened at $23 on March 20, and closed at $19/sh. The return since then was +250% to +320%, with SPXL now at $80.45/sh.
I opened an Interactive Brokers (IBKR) account in order to buy leveraged ETFs, like 2x oil & gas ETF (GUSH). It has more than tripled since my earlier post in this thread, but I bought it later. More recently, it's 6 month performance is +55%.
One point I would have agreed with 10 months ago, but not now, is that leveraged ETFs ignore volatility drag. A great example is GUSH, which aims for a return of 2x XOP. In the past 6 months, GUSH (+55.24%) didn't achieve 2x of XOP (+32.19%). But wait! Over 3 months, GUSH (+165.46%) beats it's multiple of 2x XOP (+80.19%). One time frame has volatility drag, another overlapping time frame shows it's gone. I think leveraged ETFs are aware of volatility drag and take steps to mitigate it.
