South Korea's Kospi index surged by 2.2% to reach a record high of 6,355 on Tuesday morning, before paring some of its gains later in the session. According to NS3.AI, the rise was driven by robust demand for memory chips linked to the expansion of AI infrastructure. Samsung Electronics saw an increase of over 2%, while SK Hynix experienced a jump of 3.86%, setting a new intraday record ahead of its first-quarter earnings report scheduled for April 23. The performance of these major tech companies underscores the growing importance of AI-related technologies in the market.
