 - South Korea’s KOSPI set an all-time closing high at 4,221.87 on Nov. 3, powered by chipmakers after Nvidia’s pledged GPU supply and cooperation signals with Samsung and SK hynix.
 - The Seoul rally quickly met profit-taking on Nov. 4, with the KOSPI down about 1.6% late morning as foreigners and institutions sold and leaders like Samsung Electronics and SK hynix retreated.
