  "account": "On October 22, South Korea's KOSPI stock market experienced a significant drop, falling more than 3% and narrowly avoiding a breach of the 5,500 level. This decline was primarily driven by a heavy selling surge, especially in large-cap semiconductor stocks. The KOSPI and KOSDAQ markets, which had previously shown strong resilience due to global market tailwinds and bargain hunting, saw all their gains erased in a single day as investor sentiment became increasingly pessimistic. The index closed at 5,533.77, down 201.89 points (3.52%) from the previous day, after opening at 5,670.11, down 65.55 points (1.14%). The decline was exacerbated by concerns over profitability in the AI industry and caution regarding the earnings of major tech companies, along with a domestic and international supply and demand vacuum. In the KOSDAQ market, the index fell to 764.10, down 28.66 points (3.62%). Institutional investors led the selling offensive, netting out 462.1 billion won, while retail investors tried to counteract the trend by net buying 380.2 billion won and foreign investors by 59.2 billion won. However, these efforts were not enough to prevent the overall decline. The two major semiconductor bellwethers, Samsung Electronics and SK hynix, saw substantial drops of 4.03% and 5.72% respectively, further impacting the index. Additionally, other top market capitalization stocks in various sectors, including battery, automobile, and platform-related industries, experienced weakness, contributing to the downward trend. The day's trading ended with the won-dollar exchange rate at 1,324.2 won, marking a slight decline of 1.0 won from the previous day, and continuing a consecutive five-day low. This aligns with the weakening global dollar, which has become 15% less valuable compared to its June peak. Experts attribute the market's plunge to a combination of short-term market fatigue and uncertainty surrounding the global AI ecosystem, particularly as the semiconductor sector's volatility has intensified, weakening the overall resilience of the index.",
