On June 5, Shanghai Fudan Microelectronics fell 5.03% in regular trading, trading at HK$28.7/share, with trading volume of HK$152 million. The decline reflects an ongoing semiconductor sector correction that has persisted since late May.

The selloff was initially triggered by the National Integrated Circuit Industry Investment Fund (Big Fund) reducing its holdings in multiple core semiconductor names, including SMIC, Shanghai Silicon Industry, and Debond Technology. According to HKEX filings, the Big Fund lowered its long position ratio in SMIC from 8.08% to 7.99%, while cumulatively selling over 33 million shares in Shanghai Silicon Industry between May 20 and May 28. Industry analysts noted that after sustained rallies, the semiconductor sector reached historically elevated crowding levels, creating conditions for technical correction.

The broader sector remains under significant pressure today, with Montage Technology down 9.55%, GigaDevice down 8.46%, Hua Hong Semiconductor down 7.86%, SMIC down 7.36%, and Innoscience down 5.19%. Market participants continue to digest high valuations and capital reallocation dynamics, though analysts maintain that AI-driven demand and domestic substitution trends provide long-term fundamental support for the industry.
