This sounds similar to 3x leveraged ETFs. It's not as magical as it may sound as long term performance won't match the same long term as TSLA. They are using leveraged instruments such as options and other things to match the daily fluctuations (if it's daily matching), but paying fees and such in the long term. I don't fully understand it's details I used it for trading when SPY was super volatile, but then got freaked out with all these warnings and bailed as I didn't really understand what was going on behind the scenes.
Just remember nothing is free. If you are getting something on the front-end you're giving something up on the back-end. So you're getting 3x leverage, but losing ___________.
Here's a primer:

Could still be worth it for you as it may outperform stock in the long-term, I just like to know what I'm giving up and how much, otherwise seems too much like a dice roll.
