Asia-Pacific markets advanced Wednesday after Wall Street rose on the back of a tech rally, led by chipmaker Nvidia
, with South Korean stocks leading gains.

Shares in the artificial intelligence darling advanced nearly 3%, extending Monday's gains and driving Nvidia's market cap past Microsoft's for the first time since January. Chip companies Broadcom and Micron Technology rose more than 3% and 4%, respectively.

South Korean markets rose as opposition party leader Lee Jae-myung won the presidential election. The Kospi index popped 2.44% to hit its highest level since August last year, while the small-cap Kosdaq advanced 1.18%.

Lee's "election pledge has placed considerable weight on enhancing the value of the Korean stock market," John Cho, Korea equity portfolio manager at J.P. Morgan Asset Management, said in a note.

His plan to amend the commercial law, which will broaden the legal duties of board members to include protecting the interests of minority shareholders, will "encourage boards to make fewer value-destructive decisions and more value-accretive ones," Cho explained.

Looking ahead, he expects the incoming South Korean government to adopt aggressive fiscal stimulus to revive the domestic economy while also "pragmatically" handling international trade matters.

"We believe that the domestic economy is set to rebound from a low base in 2H 2024 / 1H 2025, and we continue to be positive on the globally competitive and uniquely positioned manufacturers, including HBMs [high bandwidth memory] for AI, health and beauty, and heavy industries," Cho added in a Wednesday note.
