1) PFE stock falls after a quarter when they beat earnings but fail to raise annual guidance.
2) PFE stock falls after an earnings miss but when management pointedly reiterates annual guidance.
It's actually somewhat logical for the stock to fall in circumstance #1 since if management is taken at its word, failure to raise guidance after a decent earnings beat would imply weakness in later quarters. And the stock market is a discounting mechanism.
But if management is to be taken at its word and they reiterate annual guidance after missing, it just means that the later quarters will be doing that much BETTER than originally expected.
And being a discounting mechanism, the stock really should RISE on such a combination of years - especially when the company has a fine history of delivering on their annual estimates.
The only irrational is you, and it is about time you accept it or else you'd be considered a notch beyond "the irrational." For a long time the stock has been very weak. If that doesn't say something to you, waht does? Your superior methods? Enough Yo!
