Have we just seen the latest way to make a ton of cash? I know that this was a freakish chain of events, but if you wanted make a tidy profit, put out a news item like this on a company; watch the stock nosedive and then go in and buy at the bottom. Once the "error" is found to have no substance, the price goes back up and you can sell back at at a profit. Nice day's work. It would also allow someone buy a fair size piece of the company if they were thinking of a takeover. At a certain point, they need to declare their intentions, but buying cheap right up to that threshold would leqave extra cash for gaining additional shares later.
