Kospi Falls 5.46% as South Korean Semiconductor Stocks Face Heavy Selling Pressure

📉 On October 13, the Kospi closed at 6,035.35 points, down 5.46% after briefly falling below 6,000. Intense selling pressure triggered a five-minute suspension of program sell orders.

📊 Samsung Electronics fell 7.39%, while SK hynix plunged 10.09%. Foreign investors recorded net sales exceeding 4 trillion won, weighing heavily on the market despite buying interest from domestic investors.

🔍 The decline came as China's CXMT announced progress in its 4FÂČ DRAM architecture and plans to introduce DDR5 RDIMM server memory in 2026, raising concerns about growing competition in the semiconductor industry.

🌐 The selloff reflects increasing caution among international investors over technology stock valuations and memory industry earnings prospects, although Samsung and SK hynix retain significant advantages in the HBM segment.
