Interesting that 3M options given on 5/9/2018 with an expiration on same day (5/9/2018) that’s just weird. So they’d have to used the same day, wonder if this is a typo. 3M options cost $40,500 @ $ .0135 strike price. Given nothing happened that day this filing appears to be just some clean up documentation.
The PPS high on 5/9/18 was $ .0140 but the open and close this day was $.0135, volume that day was 812,114, not even close. I am thinking nothing happened, and means nothing to anyone, other than a tidy up of reporting docs.
