Asian Chip Stocks Surge Following Wall Street's AI-Fueled Rally

Asian semiconductor stocks posted broad gains on Tuesday, taking their cue from a powerful rally in U.S. technology shares fueled by renewed investor confidence in artificial intelligence spending. South Korea’s LG Electronics was a standout performer after receiving a key supplier qualification from chipmaker Nvidia.

Wall Street Sets the Tone

The positive momentum for Asian markets was established during the overnight session in the U.S. The tech-heavy Nasdaq Composite jumped 2.3% to a record close, while the S&P 500 gained 1.5%. The rally was led by AI-related stocks, with the Philadelphia Semiconductor Index surging 4.3%.

Major U.S. chipmakers saw significant advances, with Advanced Micro Devices (AMD) climbing nearly 10% and both Intel and Arm posting double-digit percentage gains. The risk-on sentiment was further supported by softer U.S. Treasury yields and lower oil prices, which can ease pressure on technology stock valuations.

Asian Chipmakers Follow Suit

The rally extended across the Asian AI supply chain, with South Korean firms leading the charge. The country's tech-heavy KOSPI index rose 1.5%, driven by gains in major chipmakers:

• SK Hynix climbed 2.5%.
• Samsung Electronics gained 2.0%.

LG Electronics was another notable mover, jumping 6% after Nvidia qualified its coolant distribution unit for the chipmaker’s DSX AI Factory platform. Elsewhere in the region, Taiwan Semiconductor Manufacturing Co. (TSMC) added 0.4%, while Chinese firms like Semiconductor Manufacturing International Corp. (SMIC) also saw their shares strengthen.

Broader Market Impact

The widespread gains underscore continued investor appetite for companies directly involved in building AI infrastructure, even as questions about the broader economics of AI models persist. Hong Kong’s Hang Seng index gained 0.4% and the Shanghai Shenzhen CSI 300 added 0.7%, though performance among broader Chinese technology stocks was mixed. Japanese markets were closed for a public holiday.
