A brutal sell-off in global technology stocks sent shockwaves across Asia, with South Korea’s market bearing the brunt of the fallout. The sharp downturn was so severe it triggered trading halts, highlighting the economy's deep vulnerabilities.
A Global Tech Tremor
Global
technology stocks took a nosedive last week, driven by fears of a slowdown in the artificial intelligence (AI) sector. The rout began on Wall Street, where the tech-heavy Nasdaq Composite index fell 5.5% on Thursday, its worst day in 19 months. The sell-off was linked to the results of the US midterm elections, which sparked concerns among investors about the potential for tighter regulation on AI infrastructure and data centre construction. This uncertainty wiped out an estimated $2.5 trillion in market value on Thursday alone, as investors began to question the massive capital expenditures underpinning the AI boom. The pain quickly spread from the US to markets across Europe and Asia.
Panic in Seoul
The spillover was particularly severe in South Korea. The benchmark KOSPI index plunged more than 8% within minutes of the market opening on Friday, November 6. The dramatic drop, which pushed the index below the psychologically important 5,000-point level, prompted the Korea Exchange (KRX) to activate a 'circuit breaker', halting all trading on the main board for 20 minutes to prevent further panic selling. It was the tenth time a circuit breaker had been activated this year. Shortly after trading resumed, a 'sell sidecar' was also triggered to curb program trading. By the end of a brutal week, the KOSPI had fallen by 11.7%, its worst weekly performance in recent memory.
Chipmakers at the Epicenter
South Korea's acute vulnerability to the tech slump stems from its heavy economic dependence on a handful of giant semiconductor companies. These firms are critical suppliers to the global AI industry. When fears of an AI investment slowdown hit, they were the first to feel the impact. Shares in market titans Samsung Electronics and SK Hynix, two of the world's largest memory chip makers, plummeted. Over the course of the week, Samsung Electronics lost over 16% of its value, while SK Hynix plunged by more than 20%. Given their enormous weight in the KOSPI, their collapse dragged the entire index down, a clear illustration of the concentration risk embedded in the South Korean market.
The Knock-On Effects for Global and Indian Markets
The events in Seoul serve as a stark reminder of how interconnected global financial markets have become, especially within the tech supply chain. The correlation between the KOSPI and the Nasdaq has recently been extremely high, meaning they essentially move in lockstep. For India, the situation presents a complex picture. While a global tech downturn could create headwinds for India's own formidable IT and software services sector, it may also present opportunities. The heavy concentration of the South Korean and Taiwanese markets in hardware and chip manufacturing makes them uniquely exposed to this type of selloff. Indian markets, with a more diversified tech landscape that includes software, fintech, and digital services, might prove more resilient. However, sustained foreign investor outflows from emerging markets, like the heavy selling seen in Korea, could impact sentiment in Mumbai as well. Investors will be watching closely to see if the AIled market correction translates into a broader deterioration in economic fundamentals or remains a contained, if dramatic, repricing of risk.
