KOSPI trading is suspended as the tech sell-off forces a halt. A forced pause is a liquidity signal for the tape, not just another red day in chip names. The reopen is the tell.

What happened: South Korea's bourse operator activated a circuit breaker for the KOSPI on Friday, halting trading of KOSPI-listed shares for 20 minutes from 9:03 amid a tech sell-off. Key numbers: Index fell more than 8 percent from the previous session's close. Tenth circuit breaker activation by the KRX this year. Why it matters: The index came under heavy selling pressure after a tech rout on Wall Street, triggered by concerns that Democrats' midterm victory could slow the build out of artificial intelligence data centers.
