Samsung Electronics shares fell 4.7% to KRW272,500 ($197) as South Korean semiconductor stocks faced a sell-off. SK Hynix also experienced declines, reflecting concerns over high memory chip prices and insufficient demand growth. Foreign investors have been net sellers, exacerbating the downturn amid geopolitical risks affecting supply chains for critical materials like helium and bromine. Despite current challenges, Samsung and SK Hynix are positioned as exclusive suppliers of HBM4 memory for Nvidia's upcoming AI accelerator, with projections of a 20% supply deficit in memory chips through 2030. However, Samsung's recent financial struggles, including a significant profit drop in late 2022, highlight investor caution amid ongoing market volatility.
