Emerging-market equities saw a significant decline today, with a gauge of these stocks falling by 3.7%, marking the largest drop since April of the previous year. This downturn was largely attributed to a rout in South Korea's technology sector, which also impacted global risk sentiment and led to a weakening of most developing-nation currencies.
The primary driver of the selloff in South Korea was the poor performance of its chipmaking heavyweights. Samsung Electronics Co. and SK Hynix Inc. both saw their stock prices plummet by more than 12%. This substantial decline in these key technology firms pulled the Kospi index down by 10%, triggering a 20-minute trading suspension on the Korea Exchange. The selloff was further exacerbated by a broader pullback in stocks linked to artificial intelligence, including Taiwan Semiconductor Manufacturing Co.
Analysts noted that the Kospi index has become heavily influenced by Samsung and SK Hynix, which together constitute over half of its market value. The rapid ascent of the index past the 9,100-point level on Monday, driven by these chipmakers, has raised concerns about the sustainability of the AI-driven rally. Volatility has increased significantly, with market experts expressing worry about the high level of retail investor engagement, especially with the recent approval of leveraged single-security ETFs.
The impact of the Korean tech rout was felt across Asian markets. Japan's Nikkei 225, Shanghai's SSE Composite index, Hong Kong's Hang Seng index, and Taiwan's Weighted index all fell between 1% and 4%. The Indian market also experienced ripple effects, with the Nifty 50 dropping 1.16% (278.80 points) to close at 23,824.10, and the Sensex shedding 893.39 points to settle at 76,200.68. The IT sector in India was notably affected, declining by over 2%, alongside other sectors like metal, which fell 3% due to concerns over global metal prices and demand. Pharmaceutical and healthcare stocks, however, bucked the negative trend, attracting defensive buying.
Overall market sentiment was cautious, reflecting concerns about the sustainability of the AI-driven rally and broader valuations in the tech sector. The India VIX, a measure of market volatility, rose over 9% to approximately 14, signaling heightened near-term market fluctuations.
