On November 6, SMIC falls 5.85% in regular trading, trading at HK$45.08, with turnover of HK$339 million.

The clearest market catalyst in available public information is a same-day sector-led pullback, with semiconductor names broadly under pressure alongside renewed concern over elevated valuations and heavy capital spending.

Public market reports indicate SMIC was cited as declining amid broader semiconductor weakness, while investors continued to debate whether China AI chip manufacturing names are priced richly relative to fair value and whether high capex could restrain free cash flow. That backdrop aligns with moves in peers, including Montage Tech down 14.55%, GigaDevice down 9.6%, Iluvatar CoreX down 7.39%, and Hua Hong Grace down 2.53%.
