Groupon 1, Reality 0

More here about the Groupon IPO. Note that it's a tiny sale compared to the full equity value of the firm.

Another neat point is the mention of LinkedIn's 9% price drop when they announced more shares sold after IPO. That could be an effect of the investor that sold, but who knows. Whatever it is, managers will have to make up the drop somewhere else.

Here's another link to LinkedIn's IPO info, from the New Yorker. They had a small chunk issued, too, back in May of this year. Yahoo Finance for LinkedIn looks like this.

The article mentions Pandora, the online radio firm that debuted recently too. Yahoo Finance here.

Finally, compare all of these to the grand-daddy of them all: Google.

And Apple, I guess.
