Korean stocks extended their gains late Wednesday morning as individual investors went bargain hunting following the previous session's massive sell-off in technology stocks.

After opening 1.86 percent higher, the benchmark Korea Composite Stock Price Index (KOSPI) added 272.43 points, or 3.32 percent, to 8,476.27 as of 11:20 a.m.

Overnight, Wall Street closed lower as sharp declines in memory chip and semiconductor stocks weighed on investor sentiment amid broader concerns about the artificial intelligence sector.

In Seoul, blue chip technology shares traded in positive territory.
