Memory chip stocks are trading sharply higher in the pre-market session, driven by a report that Singapore's state investment fund, Temasek, is planning a significant investment in industry giants Samsung and SK Hynix. The news, which sent shares of the two South Korean memory makers up more than 8% and the KOSPI index over 4%, is being viewed as a major vote of confidence in the AI-driven semiconductor supercycle and has sparked a rally across the entire sector. This catalyst adds to an already bullish backdrop of tight memory supply and soaring demand from data centers.
