Trading was stopped on the stock market — home to companies such as Microsoft, Apple and Google — after a technical issue of unknown variety.
Here’s more from a report in The Wall Street Journal:
The issue stemmed from a data feed that provides market data for Nasdaq-listed securities, exchanges said in notices sent to traders. Exchange officials scrambled to resume trading and to figure out what had happened. Regulators said they were communicating with market players but offered no details.
And here’s more from The New York Times:
Nasdaq told traders that it was “halting trading in all” stocks listed on the Nasdaq exchange “until further notice.” The exchange said the issue was a result of problems with the system on which trades are recorded. Trading was also halted on all Nasdaq options markets.
Traders were scrambling to assess the impact of the outage in some of the most popular and widely-traded stocks. At least some trading was able to go ahead on other trading platforms and exchanges.
Nearly all of the major technology companies in the Seattle area are traded on Nasdaq, from Amazon.com to F5 Networks to Zillow.
