Trading halted on Wall Street after stock plunge triggers 'circuit breaker'

By Lucy Bayly
The Dow Jones Industrial Average fell by 2,000 points Thursday morning after President Donald Trump’s long-awaited response to the coronavirus epidemic triggered a massive sell-off on Wall Street.
The S&P 500 plunged by 7 percent, triggering a circuit breaker, which halts all trading on the New York Stock Exchange for 15 minutes.
This is now the worst week for markets since the 2008 financial crisis, with trading halted twice on Thursday morning. The first time came after all three major averages sank below the 5 percent "limit down" marker in premarket activity.
