  "account": "On October 15, the domestic stock market experienced a significant downturn as concerns about inflation in the United States and uncertainty surrounding AI industry investment returns combined. To curb the sharp decline, circuit breakers were triggered in both markets. The domestic market faced extreme risk aversion due to substantial foreign selling and the sharp decline of large-cap semiconductor stocks, which drove the index lower. The KOSPI index started at 5,673.01, fell 335.80 points, and closed at 5,554.22, marking a 7.57% drop. This was the lowest level in six months.

The KOSDAQ index also declined by 7.65%, reaching 760.82, down from 784.45. Foreign investors net sold about 3.6241 trillion won worth of stocks, primarily targeting semiconductor sectors like Samsung Electronics and SK hynix. Large-cap semiconductor stocks saw the most dramatic falls, with Samsung Electronics down 9.5% and SK hynix down 11.1%. Other major companies, including Samsung Electro-Mechanics, LG Innotek, Daeduck Electronics, LG Energy Solution, Hyundai Motor, KB Financial Group, and Samsung Life Insurance, also suffered losses. Despite the overall market downturn, pharmaceutical and biotechnology stocks performed relatively better, with Samsung Biologics, Yuhan, and Celltrion closing higher.
