After a decade languishing in the wilderness, technology IPOs have once again got investors chomping at the bit. Almost $10bn has been ploughed into tech IPOs so far this year - that's 10% of total IPOs globally and triple the 2008 figure.
Social media has stoked the biggest frenzy. When business networking site LinkedIn made its stock market debut at a valuation of around $4bn, its shares soared by 109%. Online music service Pandora also priced above expectation and discount site Groupon hopes to raise up to $750m. This is paltry in comparison to the potential of Facebook, said to be preparing an IPO early next year with a $100bn valuation.
Is another tech bubble inflating? Are the emperor's new clothes about to be exposed for what they really are? Maybe, but even LinkedIn's debut doesn't come close to the highs of the original dotcom boom - VA Linux posted an eyewatering 698% first-day gain back in 1999.
