This is the 2X leveraged ETF. From a peak of 38.61 a few months ago to now 18.10.

I remember taking a position in this (when it was a 3X leveraged fund) back in 2014 or 2015 (it was in the wintertime) when the ruble was in freefall. I doubled my money.

If it drops anymore, it will be too attractive for me to pass up!
