Well spotted buddy -- sorry for jumping the gun.
You do have a point though in your original post - Apple's stock ALWAYS takes a hit after a keynote, the opposite of what happens to most companies after a product release or major announcement, even within the same industry. If you had a lot of money you could make a lot more by betting on this. Buy up stock when you see the post event/keynote dip and sell a week or two later when the stock has normalised again. Laugh. Rinse and repeat.
Sep 19 - APPL stock price drops $1 to on heavy trading. (double the volume of the previous day) Buy
Sep 22 - APPL stock price rises to $1 above pre-keynote level. Sell.
If you had $2,000,000 to play with and you aren't greedy, you've just made about $200k in 3 days.
It seems that there is a lot of expectation building that then gets shot down right before an Apple event from various overseas sources. It is either stupid analyst CYA tactics, or orchestrated to try to hold Apple down, both in the eyes of investors and the consuming public.
I actually think it is a bit of both, or at least happens to serve interested parties' dual purpose.
PS - then there is this whole bendgate issue - someone should definitely review whether anyone made bank off of that fiasco, especially anyone connected in any way to that idiot who posted that YouTube video that got the 40+m views. Anyone who made a big buy on that day is going to make a lot of money selling it off in the short term.
