Semiconductor stocks in the Hong Kong market are exhibiting strength today.

Changguang Chenxin has surged by more than 18%, while SMIC and Chip One have gained over 4%. Biren Technology, Iluvatar CoreX, and OmniVision Technologies Group are all up more than 3%.

This movement follows news that global memory leaders Samsung and SK Hynix are planning substantial new chip production capacity projects, with a combined scale reaching up to 800 trillion Korean won. Each company intends to construct two new dedicated chip fabrication plants, significantly boosting the global supply layout for high-end semiconductors.

Analyst reports widely suggest that robust demand may accelerate the upcycle for semiconductor materials, presenting a broad scope for domestic substitution. The capacity expansions by memory and wafer foundry manufacturers are expected to hasten the localization of semiconductor materials in China, with leading companies positioned to benefit from the dual drivers of import substitution and growing demand.

In a separate assessment, a trader from Goldman Sachs, Ippei Yamaura, has raised concerns regarding the memory chip sector. He points to potential doubts about AI investment returns stemming from OpenAI's delayed IPO and price reductions.

The sector faces three primary downside risks, according to the trader: a deceleration in the price momentum for High Bandwidth Memory (HBM), increased competition in the DRAM market from new overseas entrants, and a broader slowdown in AI server investments. This perspective indicates that the memory chip and AI infrastructure sectors are confronting structural pressures, rather than merely short-term volatility.
