• Stockholm bourse fines Morgan Stanley

German Commerzbank will sell Facebook securities on the Stockholm Stock Exchange when the shares begin trading on Friday.

Business daily Dagens Industri said that returns may be high, but so is also the risk.

Structured products betting on the future stock price of Facebook Inc are being sold by a number of banks as the social network raises as much as $16 billion in the largest initial public offering by a technology company.

“As the Facebook story is so hot all over the world we expect clients to immediately go into the stock through derivatives after the IPO,” Markus Jakubowski, vice president in derivatives sales at Societe Generale in Frankfurt, told Bloomberg.

Commerzbank sells two types of Facebook-paper: Mini Futures Best and Bull Certificate. Both are available with different leverage and various risk level.
