After LinkedIn IPO, Here Are Tech Bubble Survivors

Following LinkedIn's stellar debut on the New York Stock Exchange, which sets the company's market value (as of 1pm ET) around $10.2 billion— more than double the estimated $4.3 billion price during its IPO of $45 per share—many are wondering about the sustainability of the lofty valuations social-networking companies are attracting from investors.

Microsoft, for example, announced last week that it would buy Skype, a voice and video communication company, for $8.5 billion, its largest acquisition ever.

Recent reports have put a price tag on companies like Groupon, which offers discounted deals at restaurants and local outlets, for as much as $25 billion. The company is expected to go public this year. Others, such as Facebook and Twitter, are also valued in the multi-billion range.

Could this be a sign of another dot com bubble similar to the late 1990s?

CNBC.com looked at companies in the S&P Technology sector that have been in existence since at least 2000—surviving the tech bubble—and have posted positive performance in the past ten years.

The average P/E ratio for the tech sector as a whole stands at 28, while the forward P/E is 17.
