I think the AH took some pressure off a huge intraday gain, however I will go out on a branch and say stock ends up 30 dollars over the open, accounting for day trading and hft machines, which usually sell all their shares by the end of the day.
My prediction: I think it will be windy with some rain in the afternoon. Why do people continue to post their predictions? They are meaningless and have no more validity than that of the average 6th grader's.
Remember this stock is still down from its all time high, however....over 50 bucks per share in AH is the visual aid for short sellers getting margin called and shares being bought back by their respective brokers. No one saw this coming, even PCLN lowered guidance and we will easily see plus 30 pps tomorrow when the market opens. I do not think pcln goes bck to 700 soon but the bottom is definitely in.
