SICC's stock plunged 7.31% during intraday trading on Tuesday, reflecting broad selling pressure in the semiconductor sector.

The decline follows reports that China's National Integrated Circuit Industry Investment Fund (Big Fund) has been reducing its holdings in multiple core semiconductor companies including SICC, triggering sector-wide weakness. Additionally, major shareholders of SICC have recently decreased their combined stake, further contributing to the selling pressure.

Market analysts note that the semiconductor sector has been under pressure from capital rotation and profit-taking activity, particularly after recent gains driven by SiC-AI demand narratives. The combination of institutional selling and shareholder reductions has created a challenging environment for semiconductor stocks like SICC.
