Traders may have been left with sweaty palms as stock prices of some of the biggest tech companies in the world appeared to crash overnight. But, it was all down to a technical glitch rather than the bubble bursting, much to their relief.

Many Nasdaq-listed share prices were displayed incorrectly, to exactly $123.47 or thereabouts, on stock price resources such as Google and Yahoo Finance, and Bloomberg terminals.

A spokesperson for Nasdaq told CNBC the glitch was down to test data being distributed by third party financial sites.

"As part of its normal process, the UTP distributed test data and certain third parties improperly propagated the data. Nasdaq is working with third party vendors to resolve the matter," they said. The exchange told the FT trading had not been affected.

The incorrect data made it appear that the companies had lost billions in market cap: Apple appeared to plummet more than 14 per cent and Amazon by 87 per cent

But others showed a huge jump. Microsoft appeared to have gained 79 per cent and eBay more than 250 per cent.

It was all quite a fright for anyone keeping an eye on the already crazy tech stocks.
