I've owned this stock for a number of years and have seen it drop like this after what any reasonable person would believe is a very good earnings report. I've come to think that some money manager somewhere purposefully dumps a few million shares right after such reports to scare off weak hands and short term holders, and then buys them all back (or a bunch of calls) at a lower price. Every time this has happened before, the stock shoots up in the following weeks. I'm not selling a single share below $50.00. INFA had an excellent quarter and guidance is strong. When Europe eventually pulls itself out of its economic funk (it will happen sooner or later), this stock is going to take off like a rocket.
