New York Stock Exchange glitch causes Warren Buffett’s Berkshire Hathaway stock to plummet 99%

A technical glitch at the New York Stock Exchange caused an errant reading of share prices for several companies, including Warren Buffett’s Berkshire Hathaway.

Trading of shares of Buffett’s firm was halted after the stock exchange’s display showed that it was down by 99%.

Shares of other companies including Chipotle, Barrick Gold and Nuscale Power were also paused due to volatility.

The stock price of Barrick Gold was shown to be down by more than 98% before trading was halted because of the glitch.

The stock exchange said on Monday that it was investigating the glitch, which affected dozens of stocks. The issue appears to have been resolved and trading for the impacted stocks has resumed as of 11:22 a.m. Eastern time, according to NYSE. The exchange said Monday it has ruled to bust all erroneous trades in Berkshirethat were impacted by a technical glitch.

The glitch did not appear to affect the wider market.
