His post is an outright lie, he made up a rumor and posted it with the intent to profit from AAPL stock price collapse. If he was short AAPL stock then he's going to be in big trouble.

Is this your first day on the internet? People post nonsense all the time. You can’t possibly believe that it affects Apple stock.
Let me give it a try: I overheard an Apple employee say that Apple hasn’t actually made a single X unit yet, and on Nov 3rd they’re just going to ship boxes full of cotton candy! Can’t wait to see how the market reacts!
