Facebook shares jumped more than 10% within minutes of making their stock market debut on the Nasdaq exchange. Shares in the social networking site rose to $42, having been initially priced at $38 each, before falling back to trade flat. Mark Zuckerberg, 28, who started Facebook while at university, remotely opened trading on the Nasdaq earlier. He appeared via a video link from a celebration at the firm's headquarters in California. There had been a delay of about half an hour in the start of trading in Facebook shares, which analysts say reflected the huge demand for the stock. The $38 initial share price values the eight-year-old social network site at $104bn (£66bn). Strong demand had led the company to increase both the price and the number of shares available for sale. Facebook's owners are releasing just under a fifth of the company's total shares, about 421 million, which could raise about $18bn.
