The so-called circuit breaker mechanism refers to the threshold at which an exchange stops or closes market trading due to extreme declines. These levels are determined based on the closing price of the S&P 500 index the previous day. The New York Stock Exchange , Nasdaq and other stock exchanges introduced this "circuit breaker" mechanism after the stock market crash in October 1987. Since then, the circuit breaker mechanism has been modified many times. The current standard is: if the S&P 500 index falls by 7% or more between 9:30 am and 3:25 pm Eastern Time, the "first-level" suspension will be triggered; if the index falls by 13%, the "second-level" suspension will be triggered, which also lasts for 15 minutes. Afterwards, if the drop reaches 20%, trading will stop for the day.
Earlier, the US stock market actually triggered a circuit breaker only once. On October 27, 1997, the Dow Jones Industrial Index plummeted 7.18% to close at 7161.15 points, the largest decline since 1915.
At that time, the US stock market used the Dow Jones Industrial Average as the circuit breaker benchmark index. On May 31, 2012, New York Stock Exchange modified the index circuit breaker mechanism . The modifications mainly include the following aspects: First, the S&P 500 Index replaced the Dow Jones Industrial Index and was set as the circuit breaker benchmark index; second, the circuit breaker threshold was modified to 7%, 13% and 20%. The new circuit breaker mechanism was implemented on February 4, 2013.
