Computer malfunctions shook American equity trading for the second time this week, freezing thousands of securities listed on the Nasdaq Stock Market for three hours and raising fresh concerns about the fragility of exchanges.
The second-biggest American market operator, home to 3,200 companies from 37 countries, halted transactions in all of its shares shortly after noon, a decision that caused buying and selling to stop on its platform and dozens of others where the securities trade. Errors in the feed used to disseminate quotes and prices were to blame, Nasdaq said on its website.
