Actually it seems like the stock fell ~12% because they missed earning estimates for the quarter. The mood with respect to CEO change seems somewhat ambivalent. Ruiz was not popular with investors and largely blamed for running the company into the ground by not solving production problems. Some blog post level comments seem to suggest that bringing in Meyer as CEO is a mistake. Anyone from AMD / ATI out there want to pipe in on the mood in house?
""From 2001 to 2006, Meyer led the companyâ(TM)s microprocessor business,
overseeing related R&D, manufacturing, operations, and marketing."
Right. Forget Ruiz, _THIS_ is the guy who is responsible for AMD's
sorry state. Responsible for the horrible marketing. Responsible for
manufacturing problems. Responsible for the failure of K10 (aka
Bulldozer aka Core-killer aka the architecture which should have been
10h which should have kept AMD on top which should have arrived a
while ago but won't for another two years).
They really should have promoted somebody from ATI or the outside or,
I don't know, ANYONE but Meyer. Sigh. "
