Trading in shares of about 40 stocks on the New York Stock Exchange was halted for two hours on Monday morning due to a technical glitch. The glitch resulted in misquoted prices, including a significant drop of more than 99% for Berkshire Hathaway shares. The error was fixed, and any trades placed before the halt would be reviewed. The malfunction was caused by a technical issue with a data feed that displays bids and prices. Other stocks affected by the glitch included Chipotle, GameStop, and AMC. The S&P 500 rose slightly and trading in other markets remained unaffected. Trading glitches like this are rare but can happen.
