Warum ?    Weil sie der Ansicht sind, dass da nicht viel zu holen ist ...

Jim Rogers, CEO and Chairman of Rogers Holdings
 
Rogers has said he won't be buying U.S. stocks.  He told CNBC he would not buy Facebook either:
 
"I'm not buying because it's a very expensive stock. That's not the way I invest. I know it's going to come out maybe 25 times -- 15 times next year's sales. Sales! Usually when you buy stocks that are very expensive, you don't make money. At least I don't."
 
 
 
Marc Faber,Publisher of the Gloom, Boom and Doom report
 
Faber also said he wouldn't buy Facebook. He told Bloomberg TV:
 
"I never buy anything that is in the limelight and Facebook is a lot of hype and so forth. I think the valuation is on the high side. I'm not saying that you can't make any money. Maybe someone who buys at the opening--it's a flip for him and he makes some money, so on and so forth. But It doesn't meet my criteria of undervaluation. I should have bought four years ago when it was still private."
 
 
 
Barry Ritholtz, CEO at FusionIQ
 
Ritholtz told Bloomberg TV that IPOs tend not to be money makers for the public and warned that mom and pop investors need to not do what mutual funds and big investors do:
 
"I don't want to be too negative. This is a real company, with a huge reach,  nice revenues and decent profits but you know at a $20 billion valuation,  there is a ton of upside. At $100 billion, are they going to be Apple? are they going to be a $400 billion? How much upside is it? If you bought Google at the IPO at 85, hey it's a giant six-bagger. It's hard to see this becoming a $600 billion company."
