Feb 5 2018, UVXY went from ~$43 to $140. 
  
 Other than that, it's fucking *plummeted*, and has been split *multiple* times. 
  
 SVXY is the inverse of UVXY. That same day, it dropped 90%. However, it went from $50 to $500 within ~2 years.

Yea the negative feedback loop at 3:50 it happened. Wish I bought some svxy puts right before close since it went from 140 to 7 or so
