Crypto World news: On Tuesday, South Korea’s KOSPI index suffered a historic selloff after semiconductor stocks plunged, falling by more than 9%. Investors actively sold off semiconductor shares amid concerns about whether the AI investment boom is sustainable. The KOSPI briefly dropped to 6,051.19 points, a decline of 10.5%, the lowest level since April. Shares of Korea’s largest semiconductor companies, including Samsung Electronics and SK Hynix, fell by about 12% and 12.7%, respectively. Because these two chipmakers account for a large share of the total weighting in the KOSPI, their losses significantly impacted the benchmark index. Investors have become more cautious about the valuations of AI-related companies. Although long-term demand for memory chips and computing infrastructure remains strong, investors are beginning to question whether high valuations and heavy capital expenditures can be sustained.
