Shanghai Fudan Microelectronics (01385.HK) soared 5.16% intraday on Wednesday, as Hong Kong-listed semiconductor stocks rallied.

The surge is driven by a catch-up move following Huawei's landmark announcement of the "Tao (τ) Law" at the IEEE International Symposium on Circuits and Systems. The Tao Law proposes replacing "geometric scaling" with "time scaling" through logic folding technology, offering a new semiconductor evolution path independent of extreme EUV lithography. Huawei disclosed that 381 chips have been designed and mass-produced under this principle over six years, with a new Kirin chip featuring logic folding set for autumn launch.

The Hong Kong market was closed during the initial A-share semiconductor explosion, where the sector surged over 6%. The rally reflects sector-wide bullish sentiment as HK-listed semiconductor stocks close the gap with their A-share counterparts.
