Tech IPOs Go From Frozen to Overheated

I never imagined I would write this sentence: Technology IPO investors have gone almost as crazy as the private financiers throwing wads of money at tech "unicorns" like Uber.

There have been so few technology companies braving the public markets this year that investors are pouncing on the tiny handful of fresh listings like hungry wolves. They are driving up stock valuations to overheated and potentially unsustainable levels for many new public companies.
