I've been tracking couple of stocks with increasing IV with no clear events in Oct. that can be found to explain it.
On CIE, I'm going to wait and give another week to write a Oct. put to own it at 20.
MDVN - I'm going write naked put at 40. It had been speculated that it is a takeover target by other big pharma but there are other names out there with cheaper ways to speculate on it. I think the stock hitting 40 in Oct. a low probability event.
Closing position -
Disclosure: I am long MDVN.
