There will be ZERO upgrades and a myriad of downgrades although, 17 or 20 is a bit ridiculous. If this whole renesas acquisition doesn't pan out and BRCM continues to try to pursue wireless, than 17-20 is certainly a possibility.
They are all wrong. No downgrades as every analysts has a $37 to $42 price target on the stock. In other words it's all priced in. Even if they bumped down their estimates the stock is still a buy at these levels. Everyone is excited about the truning point into LTE which is why it will hold support at $24 and trade up as we near Q4.
