There was a lot of volume at the close that probably had to be settled. This is not uncommon for the closing price to change within a few seconds of close when the volume is so high all at once. Everyone was trying to position trades based on derivative positions right at close. In this case it was most likely call positions where traders took on a short position for protection, that later covered in AH, thus pushing the stock up significantly in AH. It will be interesting to see how this works itself tomorrow when real volume comes in.
btw dont think there is a law requiring a company to release after the close. they can release whenever they damn well please but investors like to see companies release when they say they will and after market close means after market close.
if it's the case that the ER came out 3 seconds before the close which is what it would have to of done, how could anyone or even a computer react to the number? are computers reading reports and linked to trading accounts or something? makes me wonder. i watched this til the close and didn't even notice it, it just happened. i didn't have my trade tracker up to look i wasn't really anticipating this to happen. and #$%$ is with all these releases lately on big companies. GOOG, then INTC, and now AMZN. such bs. and now i'm sure the stock is hanging around 10% cuz that's what happens with stocks. so we losing out on 8 bucks right now. oh well.
ya, i'm wondering why there has been no mention. that's a crazy move. 2% in less then a min. makes no sense. I was hoping that there would of been a closing adjustment, but looks like it's a little late for that at this point in the night.
