Microsoft (MSFT) blamed currency as a -4% headwind to sales. Apple (AAPL) said currency was a -1% headwind. What's the diff? Are Microsoft and Apple sales coming from such different currencies? Did Apple make 3% of revenue trading fx? I highly doubt it. Some of the difference may be due to hedge practices, but I think Microsoft is hiding some soft sales numbers in the fx effect. The currency blame game is all too common this earnings season. Many companies are blaming currency for weak sales, but could it also be that sales are just plain weak?
