Unfortunately the scumbags at thestreet.com (particularly Jim Cramer) have admitted publicly that they create false rumors to drive the stocks up and then when the rumors prove not to come true, they dump the stocks before they plummet. Jim Cramer specifically did this a couple of times (and admitted to it) when the iPhone first came out.
Example: Steve Jobs had hoped to sell 100,000 to 200,000 phones the opening weekend, but Jim Cramer (and other analysts) started spreading the rumor that Apple sold 750, 000 the first weekend; their stocks went through the roof ($150 per share) and then when the rumor was proved false, they plummeted (to $129).
And he is not in prison? I am no expert but it sounds like what he is doing is questionable at best. I thought the Sarbains-Oxly Act (spelling?) included laws around this?
Anyway, I am waiting for Apple to announce a special Ginza Apple Store event for the Japan launch of hte iPhone!
