Korean stocks surged more than 5 percent Wednesday, on a semiconductor rally boosted by the ongoing U.S. chip giant Nvidia's global artificial intelligence (AI) conference. The Korean won strengthened against the U.S. dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) closed up 284.55 points, or 5.04 percent, to 5,925.03.

The index came under strong buying pressure from foreigners and institutional investors, triggering the Korea Exchange (KRX), the country's main bourse operator, to issue a buy-side sidecar near the closing bell.

Program trading for the KOSPI was suspended for five minutes at 2:34 p.m., according to the KRX.

Investors' appetite for semiconductors increased, following remarks from Nvidia's Chief Executive Officer (CEO) Jensen Huang on Samsung Electronics, Lee Kyoung-min, an analyst at Daishin Securities, said.

During the ongoing four-day event in California, Huang said on Monday he wants to "thank Samsung, who manufactures the Groq LP30 chip" for the company, adding that the chips are in production and would be shipped in the second half of this year.

"The stock market's sensitivity to geopolitical issues in the Middle East is markedly declining," Lee added.
