On May 27, SMIC (00981.HK) rose 3.73% in regular trading, trading at HK$88.0 per share with turnover of approximately HK$890 million, extending its strong rally from the prior session.

The continued upward momentum is driven by the aftereffects of Huawei's landmark announcement of the \"Tau (τ) Law\" at the IEEE International Symposium on Circuits and Systems. The new principle proposes replacing traditional \"geometric scaling\" with \"time scaling,\" using logic folding technology to compress signal propagation delay and boost transistor density without relying on extreme EUV lithography processes. Huawei disclosed it has designed and mass-produced 381 chips following this law over the past six years, with a target of achieving transistor density equivalent to 1.4nm by 2031.

As China's leading foundry, SMIC is viewed as a primary beneficiary of this paradigm shift, as the Tau Law elevates the value of mature-node manufacturing capacity. Additionally, SMIC's previously announced CN¥40.6 billion acquisition of SMIC North further strengthens its expansion narrative. Within the Semiconductors sector, Hua Hong Semi rose 5.78%, GigaDevice rose 8.97%, Montage Tech rose 7.14%, and Innoscience rose 7.21%.
