The New York Stock Exchange said it was investigating a technical glitch that led to dozens of trading halts for US-listed companies, in the second issue to hit the world’s biggest exchange in less than a week.
Berkshire Hathaway’s class A shares, appeared to plunge 99 per cent before a trading pause — which prohibits trading activity in exchange-listed securities at prices outside specified price bands — was initiated.
“NYSE Equities continues to investigate a reported technical issue,” the exchange said in an update shortly after 10am local time on Monday.
A spokesperson for the exchange told the Financial Times the glitch did not appear to be the result of a cyber attack.
The incident comes just days after a blip that caused live data for indices including the S&P 500 to disappear from investors’ screens for about an hour.
