Experts predicted facebook's IPO would go sky high.......but it fell flat. What happened?

You have no skills in judging a stock, I am afraid.

An EXPERT could be defined as a SPURT under pressure.

A lot of the so-called experts in the media were paid to say the things they did. It was marketing fluff. Not really a pump & dump...but then again not far from it either. They were making claims based on what-might-be in the future...as if that future was reality.

There is not enough data to decide which way this stock goes...though I tend to feel that the stock will drift negative.

The other guy here who says he uses TA thinks it will take off on Monday and points to the final hour as indications of it. He might be right, but I don't put as much credence in that since I believe this was nothing more than day-trader positions being vacated since they don't have the confidence in holding their positions over the weekend...not normal trading. And also the fact that in spite of this 11th hour trading increased activity...the price was driven back down to where it basically started the day.

You need to do some reading and learn some investing skills. You will never be rich doing this by asking opinions in this fashion. You don't have the tools necessary to eveluate them.
