On Monday (local time), U.S. stocks rallied, with the Nasdaq Composite rising 2.3 percent. The S&P 500 gained 1.5 percent, while the Dow Jones Industrial Average added 0.7 percent.
Investor sentiment improved sharply, backed by a broad rally in AI-related stocks as well as falling oil prices and softening U.S. Treasury yields.
In Seoul, most market heavyweights traded higher.
Top market cap Samsung Electronics rose 2.55 percent, and chip giant SK hynix gained 3.21 percent.
SK Square, the parent company of SK hynix, advanced 3.02 percent, while Samsung Electro-Mechanics, an electronics component affiliate of Samsung Electronics, jumped 6.58 percent.
