Institutions own over 65% of AMZN. Look what they just did to MSFT and NFLX in after hours, the day of ER. MSFT was expected to beat ER, and they did, but it didn't matter. All institutions took out puts, and when market was closed they yoinked everything, crashing the price and killing all weekly calls immediately. They cashed in on their puts and next week buying it up at discount. There is a lot of shady stuff going on this quarter. I would not bank much on something that seems too good to be true.
