Don't be so sure, good chance Wyeth might REGISTER the shares for sale in a giant secondary, so probably there really is NOT a lid on the stock at this point. Plenty of time to go up. Well think about that shorts...you may not get your wish that fast... maybe there will be some covering instead when it doesn't drop as you all expect. Of course that is if the terrorist pos stay in check.
What would be the motivation for a fund manager to buy 20 million shares of amgen stock? Are there any fund mgrs out there that are willing to make a private transaction for 800 million? I don't think so, let's see whether Wyeth starts pimping amgen shares out tomorrow. There is no restriction after 10/15 and Wyeth can start the sale if they so choose.
