SK hynix's share price is displayed on the dealing room of Hana Bank in central Seoul on Oct. 28, after the chip giant posted a record-high operating profit and revenue in the third quarter.

A buy-side trading curb on the Kospi was activated Wednesday morning as the index spiked more than 4 percent, lifted by strong AI-driven chip earnings. 

The curb, locally known as a sidecar, suspended program trading of Kospi-listed shares for five minutes from 9:53 a.m. It is triggered when the Kospi 200 futures index rises 5 percent or more and stays there for at least one minute. 

The Kospi opened 2.23 percent higher and was up 255.92 points, or 4.54 percent, at 5,894.26 as of 9:55 a.m.
