How This Year’s Tech IPOs Are Doing, And Who’s Next

Bubble or not, 2011 may go down as the year of the tech IPO. Not since the last bubble have we seen so many technology companies clamoring to go public. And halfway through the year, we still have many more companies who will be listing on either the NASDAQ or the NYSE in the next six months. Here's a roundup of the tech companies that have gone public, where they are trading now, and who we can expect to see ringing the bell next. Professional social network LinkedIn probably had the biggest IPO in terms of hype this year because it was one of the first big social media companies to go public. After pricing its IPO at $45 per share on the New York Stock Exchange, LinkedIn began trading at $83.00 per share on May 19, giving the company a $7.8 billion market cap. In the first day of trading, shares popped up to as high as $122.70, soaring past a $10 billion valuation.
