There was no malfunction. XIV did EXACTLY what it was suppose to do. TVIX and UVXY also do EXACTLY what they are suppose to do. There are no free lunches out there. Maybe an old rotten banana laying around every now and then. But that's about it.
Mav or anyone else out there - have y'all heard anything from Jane street or other prop firms? I've heard of a few blow ups so far.. No firm ending events, but some big set backs..
