Asian markets on Wednesday looked like two parallel worlds existing within the same universe. In the first world — inhabited by memory chip makers and AI accelerator manufacturers — euphoria reigned. Japan’s Nikkei 225 surged to a new all-time high, climbing above 66,428 points.

Every new data center, every large language model, every Nvidia accelerator devours gigabytes and terabytes of HBM memory — a segment where SK Hynix holds a leading position.

And as technology giants like Google and Amazon announce fresh investments in AI infrastructure, the Korean memory maker can calmly count its...
