What that the analysis was quite so simple. First, trailing PE is a virtually worthless statistic to look at for a growth company. It only tells you what has happened over the past four quarters and nothing about the future. For a company like Apple, the forward PE (currently at 24:1) is far more important, since it represents a consensus estimate of future earnings. If Apple fails to grow EPS at something like the difference between trailing and forward PE, and/or does not confidently predict that level of growth going forward, then they will probably be punished by the market. But even that analysis is too simple because the market values stocks based on far more than simple numbers.
Here's a good bottom line which has worked well in the past: If Apple doesn't beat expectations by at least 10%, then the stock will generally be drubbed the next day, because investors have already priced in at least consensus expectations. They want more and can be very disappointed when they don't get it.
