LinkedIn shares more than double after IPO

Investors keen to get in on the online networking crazemore than doubled the price ofLinkedIn Corp.'s shares on themorning of its IPO.

The initial public offering was priced at $45 US, but demand caused the price to double to more than $90 shortly after opening on the New York Stock Exchange on Thursday. Late in the afternoon, the stock was up even further, to $95.

The pre-market IPO price gave LinkedIn a market value of more than $4 billion, the highest for a U.S. internet company taking its first bow on Wall Street since Google Inc. went public nearly seven years ago. That value itself has now more than doubled.

Filings say the company made$3.4 million in profit last year.

Mutual funds, pension funds and other major money managers got the first chance to buy most of the IPO's 7.84 million shares because stock in these offerings is typically sold to investment bankers' top customers.

The IPO price already was well above LinkedIn's first target of $32 to $35 per share.

The lofty appraisal of LinkedIn reflects the investors' belief that internet services connecting people with common interests will be able to make more money as the web's audience steadily expands.

LinkedIn's valuation eventually may look modest compared with other internet companies being touted as potentially going public in the next 18 months.
