AMD (AMD -4.2%) is slumping, and Intel (INTC -0.5%) and Nvidia (NVDA -0.6%) are slightly off, after Evercore's Patrick Wang joins the estimate-cutting parade, and co-worker Rob Cihra offers mixed commentary about PC demand. While holding out hope Windows 8 and China will lead demand to stabilize in 1H, Cihra notes many industry suppliers appear to have under-shipped end-user sales (which themselves aren't great) in Q4 thanks to inventory drawdowns. "Early ultrabooks have been stymied by high prices and Win8 so far looks like a remarkable non-factor.," he adds.
