Technology shares in Asia experienced a broad-based advance on Wednesday, with SK hynix leading the gains.
This positive momentum followed a rebound in the U.S. semiconductor sector overnight, which had faced significant selling pressure at the start of the week.
The South Korean memory chipmaker saw its shares close more than 8% higher in Seoul trading, while its U.S.-listed depositary receipts surged over 27% in the prior session. Earlier in the week, SK hynix shares had recorded their largest single-day decline on the local exchange amid concerns over AI capital expenditure and concentrated profit-taking by investors.
The upward trend extended across Japan's semiconductor supply chain. Advantest Corp. closed up 5.83%, Lasertec Corp. jumped 10.18%, and Tokyo Electron Ltd. gained 4.37%. SoftBank Group Corp. was a notable exception, closing down 3.26%.
In Taiwan, Taiwan Semiconductor Manufacturing Company (TSMC) shares rose 0.83%.
The strength in Asian tech equities was fueled by a recovery on Wall Street. After a sharp sell-off in the previous session, U.S. semiconductor stocks rebounded overnight. The VanEck Semiconductor ETF (SMH) climbed 2.5%, with shares of Micron Technology and Lam Research each gaining around 5%. Applied Materials and Teradyne advanced more than 3%.
Despite Wednesday's rally, some investors are cautioning that the market enthusiasm for AI hardware appears overheated. Jordan Tsvetanovski, Chairman and Chief Investment Officer of Pella Funds, noted that while demand for AI infrastructure remains robust as companies race to expand computing capacity, signs of a speculative bubble are emerging.
He stated in a financial forum, "I have observed numerous concerning trading behaviors, and the recent extreme volatility is a classic signal that the AI sector is poised for a significant correction."
Tsvetanovski added that hardware manufacturers have been the primary beneficiaries of the current AI investment boom, with every company aggressively building out computing power.
"The focus will remain on the hardware side. This is a race, an arms race. Every company is stockpiling computing resources as much as possible, with shortages in memory supply being the most direct evidence of this," he said.
