If I were going to dump 100s of millions of some stock, the last thing I would do is tell the world ahead of time.
They should want the price to tank AFTER they sell, not before. Maybe they want to depress prices with this announcement so they can buy even more .. and only THEN sell it, as quietly as the laws permit.
Yahoo have positioned themselves not as a rival but as an alternative pay per click engine. I do not think they will be dumping google stock but are doing there best to depress prices so they can buy more. Google has something that scares the **** out of yahoo, a community. Its not authorised and not organised but anyone who has ever exchanged links at high levels knows what I mean. Google has the webmasters on board.The people who influence others are still with Google. Google mistake was not to launch IPO online so company was controlled by the community not pension funds. If launched online it would have gone for more.
