Very simple. It's all about supply and demand.
AAPL daily volume is only about 14million these days, many shares bought and sold several times. The net buying or selling volume is only less than 10 million or about $4 billion each day. If APPLE just announce $20 billion buyback in next 30 days(about 20 trading days), which will equals to $1 billion net buyback from APPLE. In a $4 billion daily net supply vs demand, a $1 billion extra demand or 25% extra demand will definately tip the balance of supply and demand, will move the stock back to $500 in a weeks or so.
Sentiment: Strong Buy
AAPL will never get back to $500 again. Right now Samsung is the only problem for AAPL. But there are three Chinese manufactures coming for AAPL with bigger if not better smart phones and tablets. Basically these five manufacture the same product with different brand names. The only difference is that AAPL price tag is much higher. If AAPL doesn't come up with a new product that no one has, AAPL will drop to $200 in 2013 then below $100 in 2014.
AAPL is even worse than MSFT. At least MSFT has monopoly on their Windows and Office products. No one can copy. AAPL has no monopoly on their iPhone and iPad. Somehow Steve Jobs successfully relaunched the tablet computer from 1980's. The problem is that anyone can copy that because it is an existant product.
Sentiment: Strong Sell
Oh my god the idiots just keep on coming . . . Now I remember why we fled to IV.
It'll be back to 500 soon enough, I suspect sometime between the end of the second and third calendar quarters when it becomes evident that Apple's earnings aren't really significantly slowing, it's just that they didn't release a new "toy" for Christmas this year.
That will be more than made up for by all the 27" iMac's flying over from China every day.
They weren't shipping until January, no matter when you bought them, so Apple couldn't realize that revenue until THIS quarter.
Further, in case you missed it, Windows 8 was yet another code bloat bomb, given MicroSoft two OS's out of their last half dozen that were worth a #$%$, XP and Win7.
A fairly pathetic track record pushing more and more people and offices towards MacOS or Linux.
AAPL can not buy from open market. They have to float a tender offer and i think this will be priced around atleast 500-550. They can not buy anything in 30 days. it has to be atleast 6 months to a yr. So this is never a possibility
