Shares in some of the world’s biggest countries have suddenly plunged amid an apparent technical issue at the New York Stock Exchange.
Shares in investment firm Berkshire Hathaway appeared to have dropped by 99.97 per cent because of the problem.
Trading in the affected companies – which also included corporates such as Chipotle – was halted because of the volatility.
The exchange said it was investigating the problem, which appeared to have resulted from a computer issue.
The problem related to Limit Up-Limit Down bands, it said, which are usually set to ensure that trades cannot happen considerably higher or lower than a currency price.
