Shanghai Fudan's stock experienced a significant decline during intraday trading, plummeting approximately 5.05%.

The sharp drop follows investor reassessment of a major cooperation agreement announced earlier in the week. The company committed to paying a RMB 20 million startup fee and providing up to RMB 1 billion in cooperation funds to co-build an Integrated Circuit Engineering Technology Innovation Center with Fudan University and Guosheng Investment. While initially received positively, the substantial capital commitment appears to be weighing on sentiment.

Additionally, the stock faced headwinds from broad selling pressure across the semiconductor sector, with multiple peer companies also trading lower during the session, contributing to the downward movement.
