New Delhi: Stock market witnessed a halt in trading for the first time in more than 12 years on Friday morning after benchmarks hit circuit breakers on panic selling triggered by concerns over coronavirus pandemic.
The BSE and NSE stopped trading for 45 minutes starting from little past 9.20 am.
To curb excessive volatility, circuit breakers are triggered on the basis of three thresholds for stock movement -- 10 per cent, 15 per cent and 20 per cent.
Circuit breaker limits
The BSE and the NSE compute the index circuit breaker limits for 10 per cent, 15 per cent and 20 per cent levels on a daily basis based on the previous day's closing level of the index rounded off to the nearest tick size, HDFC Securities said citing regulatory framework.
