Trading Performance – 10 December 2025
On 10 December 2025 the company’s shares reached a 20 % limit‑up. The rally was part of a broader surge in the Hainan‑free‑trade‑port sector, which recorded a 6.72 % gain that day. The Hainan “15‑5” development plan was announced the same day, with a focus on expanding the free‑trade‑port framework and encouraging high‑value industries. The plan’s emphasis on infrastructure, trade liberalisation and technology innovation created positive sentiment for companies linked to the Hainan region, including Hainan Ruize.

| Volume | Part of a 1.79 trillion CNY trading day; overall market saw a 1.26 trillion CNY decline in volume |

Outlook
The Hainan “15‑5” plan is expected to drive infrastructure and construction demand in the region. Companies that supply building materials, such as Hainan Ruize, are positioned to benefit from increased construction activity and policy support. However, the company’s negative profitability and high valuation volatility suggest that investors should monitor earnings updates and sector‑specific developments closely.
