More on Apple: Shares could be pressured by a downgrade to Neutral from Citi. The firm says checks indicate Apple has cut its March quarter iPhone 5 orders following a 45%-50% increase in monthly output from October to December. UBS recently said checks suggested the iPhone 5's build rate would fall sharply in the March quarter, while Jefferies claimed iPhone component suppliers saw big order cuts last week. Citi, which started Apple at Buy on Nov. 26, also thinks Samsung is doing very well. Update: Morgan Stanley responds by pointing to encouraging U.S. iPhone/iPad survey data. But a gap has opened up between U.S. and foreign iPhone share trends.
