Pulse Analysis

The latest earnings release from Nvidia ignited a fresh wave of AI‑related buying across Asia, lifting the KOSPI by 8.4% and the Taiwanese index by 3.4% while Japan’s Nikkei climbed 3.1%. Investors chased “picks and shovels” – chips, memory and server equipment – that stand to benefit from the surge in generative‑AI workloads. SoftBank’s exposure to Nvidia‑linked funds and Taiwan’s TSMC helped anchor the rally, creating a stark contrast with the weakening sentiment in mainland China where technology stocks slipped sharply after reaching intra‑day highs.

Meanwhile, mainland Chinese markets experienced a rapid intra‑day reversal, with the Shanghai Composite and Shenzhen Component falling 2% and 2.4% respectively. The sell‑off was driven by foreign investors rotating out of China‑focused tech names such as Tencent (‑3.6%) and Alibaba (‑4.5%) into AI hardware plays, a pattern reflected in the MSCI China Index’s net Southbound outflow of roughly $780 million. Domestic investors followed suit, dumping computer‑hardware, communication‑equipment and semiconductor stocks that, despite year‑to‑date gains of 30‑40%, posted single‑day declines of 4‑5%.

The episode underscores a broader reallocation of capital away from China’s internet and cloud sectors toward globally competitive AI supply chains. While the Chinese government has signaled support for domestic semiconductor development, short‑term policy tools appear limited, and the upcoming Politburo meeting may be the first chance for more concrete consumption‑stimulus measures. For portfolio managers, the divergence suggests a tactical tilt toward AI‑related equities in Taiwan, Korea and the United States, while maintaining selective exposure to Chinese chip makers that can weather periodic profit‑taking cycles. Monitoring foreign fund flows and policy cues will be critical in the weeks ahead.
