I was almost ready to sell at the open this morning, but decided to wait and see how it was trading. It was clear that while earnings were great, they didn't quite live up to expectations. I was expecting a pullback to the low $70s over the next week. It may still happen - this sudden rally following yesterday's after-hours sell-off is kinda weird.
This stock will decline when the earnings are bad or there is profit-taking. If it is profit-taking, it will be a temporary decline with a new base being formed. If it is a problem with the fundamentals (earnings) the decline will be real. We haven't seen either of these yet.
