Shares in the world's largest online social network have finally risen above the price at which they were launched last year.
Facebook shares have hit more than $US38 for the first time since the company was put on the stock market.

But on Wednesday the stock price rose as as high as $38.31 in morning trading, before falling back to close at $36.80.
The company's shares have been boosted since the it reported stronger-than-expected earnings on 24 July.
Investors have been encouraged by the fast growth of Facebook's mobile advertising revenue from which it now derives 41% of its total advertising revenue.
