On Tuesday, brokers borrowed 1.17 million shares in social networking site, LinkedIn Corp. which is newly listed on the stock market, which shows that the company is performing well. The shares of the company are one of the most expensive shares in the market and many investors consider it a significant performance.

US professional-networking website LinkedIn on Thursday made a strong debut on NASDAQ, with stocks jumping to more than double from their initial public offering (IPO).

The LinkedIn stock was set at $45 a share in the initial public offering, but it opened at $83 a share and quickly hit $94.25. The 109 per cent increase was the best since China's Qihoo 360 reported a jump of 134 per cent in March.

For all constant users of LinkedIn, Facebook and other social networking websites, who use these as a tool for managing their business contacts, the latest update that is being provided by Microsoft to Outlook, announced last week, will come as a boon.

LinkedIn, the largest professional social network website, has 50 million members all over world. Its users post their information like resumes to help them in finding jobs, or employers their employees. Twitter allows people to broadcast short messages up to 140 characters. Both the platforms have now joined hands.
