The Asian stock market downturn on Friday was a stark reminder that even after recent gains, the global economy remains vulnerable to correction. The technology sector, which has been driving growth across many regions, came under intense pressure as investors reassessed valuations in light of rising component costs and substantial investments in artificial intelligence (AI) infrastructure.
The impact was felt keenly in South Korea, where trading on the Kospi index was temporarily suspended after an 8% fall triggered a circuit breaker mechanism. This marked the third time this week, and the fifth time this year, that the 20-minute halt has been triggered on the Kospi. The index ultimately closed 5.8% lower, reflecting heightened volatility in the region's markets.
The sell-off was also evident in major US technology companies, with Apple's shares falling sharply after the company announced price increases for its iPads and MacBooks due to escalating component costs. Similarly, Microsoft experienced a dip following revelations that higher prices would be applied to its Xbox gaming consoles, again citing rising component expenses.
The substantial investments being made by large technology firms into AI infrastructure, amounting to hundreds of billions of pounds this year, have raised concerns among investors about the sustainability of current valuations. David Makaryan, a senior partner at investment firm Alpha Pacific Group, noted that traders are becoming much more selective about which companies can truly justify their market valuations.
Across the wider Asian region, Japan's Nikkei 225 index closed more than 4% lower, heavily influenced by a 12.5% drop in shares of technology investment giant SoftBank. Other major indexes in Taiwan and mainland China also experienced sharp declines, underscoring the widespread nature of the tech-led market correction.
