DONGYUE GROUP's stock experienced a significant intraday surge of 5.03%, reflecting strong investor sentiment.

The movement appears driven by a combination of favorable industry developments. Reports indicate that South Korean producers of anhydrous hydrofluoric acid, a critical material in semiconductor manufacturing, are set to begin purchasing from China with prices having risen approximately 40% since the start of the year.

Furthermore, analysis points to a significant improvement in the supply-demand structure for the company's two core segments. The fluorinated polymers business is seeing a strong recovery, supported by demand from high-end applications and the lithium battery sector, with successful price increases for products like PTFE and a rebound in PVDF prices. Concurrently, the silicone segment is absorbing previous overcapacity as industry competition rationalizes and demand grows steadily. This operational improvement was evidenced by subsidiary DONGYUE SILICONE reporting a net profit surge of 427.0% year-on-year for the first quarter of 2026.
