South Korea’s bourse operator on Friday activated a circuit breaker for the benchmark Korea Composite Stock Price Index (KOSPI) as stocks crashed due to a slump in tech heavyweights. Trading of KOSPI-listed shares was halted for 20 minutes. The Korea Exchange (KRX) triggered the measure at around 12:10 p.m. after the KOSPI plummeted more than 8 percent from the previous session’s close. The benchmark index came under heavy selling pressure as investors dumped large-cap technology stocks on profit-taking. It marked the fifth time this year that the KRX has activated a circuit breaker.
