It's based on 20-year VIX historical experiences and the trend. Here's the article:
It happens! 6/5-11/2020 it's jumping from 24 to 45 - a 21-point jump.
Some may invest in TVIX to have closed to double the position.
I will suggest at least one more possible VIX jump before 7/31/2020.
(Will share in another post for Dow/Nasdaq/NDX/ S&P to explain the logic).
Hope it helps!
