Asian chipmaking stocks climbed ahead of TSMC’s fourth-quarter earnings report, which investors view as a key industry indicator. The company is projected to post a 27% year-over-year jump in net profit, driven by strong AI chip demand and increased use of its advanced 3-nanometre production lines.

The upbeat sentiment extended beyond Taiwan, lifting Japanese semiconductor firms like Advantest and Tokyo Electron. In China, local chipmakers gained after news that Nvidia's H200 sales would be restricted there. That restriction, coupled with the debut of a homegrown AI model built on domestic chips, boosted regional stocks.

Investors are closely watching TSMC’s 2026 outlook for signs of sustained growth in the semiconductor supply chain. As the main producer for NVIDIA, TSMC's performance often signals broader tech sector health. Analysts expect its earnings to reflect robust demand from data centers and cloud computing firms fueling the AI boom.

Looking ahead, market participants want to see if TSMC will raise capital expenditure guidance, signaling confidence in long-term orders. Any positive surprise could push chip stocks higher across Asia. Samsung and SK Hynix are also in focus as memory chip leaders amid rising AI-related memory demand.
