Does this every time I've watched bro. Jack up option IV pre-ER, stupid expensive to play. Stock tanks a bit after ER, then crawls up a bit during trading the next day after ER. Option IV plummets. Pretty much almost always kills far OTM option players. Been there done that and as much as I want to play it again every time. I leave AMZN ER play alone. I haven't watched all AMZN ER's, but that's what I've witnessed when I have watched for the last 2 years.
One other thing. They release on Thursdays after hours.
Best of luck bud. Maybe it will be different this time the rest of the day.
