Shanghai Fudan's stock surged 5.18% during Monday's intraday trading session.
The sharp rise appears to be driven by market anticipation of the company's upcoming first-quarter earnings review. The board is scheduled to convene soon to consider and approve the Q1 financial report, fueling investor optimism about the company's near-term performance.
While a small number of restricted shares became tradeable around the same time, the quantity was negligible and unlikely to have significantly impacted the share price movement.
