TVIX, daily
UVXY, daily
Summary
*first, an update on the VIX, which saw a net weekly gain of 118.5% - the biggest ever?
--
As for TVIV and UVXY, I would believe (I have not fully checked) these were the biggest net weekly gains EVER.
Of course, at some point equities are going to see a bounce - at least to the sp'2040/50s, the VIX will rapidly cool - probably to the mid teens, and that will crush TVIX/UVXY.
As ever... for short term holds only!
