NYSE said it will cancel the bad trades in Berkshire Hathaway and is reviewing the erroneous halts to determine whether to cancel any of those.
A glitch during a software update early Monday led the New York Stock Exchange to erroneously halt trading on about 40 stocks and display odd trades showing a 99% drop in companies including Warren Buffett’s Berkshire Hathaway Inc.
The disruption — the third episode to hit US markets in the past week — was resolved after roughly 45 minutes when the Consolidated Tape Association, whose systems are operated by a NYSE subsidiary, reverted to a backup data centre running a different software version.
