DONGYUE GROUP (00189) bucked the broader market trend, climbing more than 4%. At the time of writing, the stock was up 4.1% to HK$11.42, with a turnover of HK$137 million. A research report from Guosen Securities highlighted that long-term contract prices for mainstream refrigerants have continued their upward trajectory in the first quarter. The report posits that the tightening constraints of refrigerant quotas represent a long-term trend; within this context, the securities firm remains optimistic about the sustained high market sentiment for key refrigerants such as R32, R134a, and R125, forecasting significant long-term upside potential for their prices. Leading enterprises with substantial refrigerant quotas are consequently expected to maintain robust profitability over the long term. Furthermore, the report expresses a positive outlook on the demand boost for fluorinated liquids and refrigerants driven by the growth of the liquid cooling industry. It also recommends monitoring the price recovery of PVDF. Public information indicates that DONGYUE GROUP is a leader in the fluorine and silicon industry.
