LILIANG DIAMOND’s Performance

  • Stock symbol: 000000
  • Closing price (12 Oct 2025): 35.75 CNY
  • 52‑week range: 25.78 CNY (low on 8 Apr 2025) – 40.46 CNY (high on 23 Dec 2024)
  • Market capitalization: 9,304,734,868 CNY
  • Price‑earnings ratio: 115.86

During the 14 October session the shares of LILIANG DIAMOND were not reported to have reached a limit‑up. However, the company’s sector, “synthetic diamond,” experienced significant gains across multiple stocks. Notably:

  • Power Diamond (力量钻石) closed at a 12.53 % increase with a turnover of 10.78 billion CNY, a record since 25 Dec 2024.
  • Huifeng Diamond (惠丰钻石) and Qianfang Diamond (四方达) also posted gains exceeding 10 %.
  • The sector’s performance was supported by a recent announcement from the Ministry of Commerce and the General Administration of Customs, which imposed export controls on various super‑hard material products. The controls are expected to create a supply‑side advantage for domestic producers.

Implications for LILIANG DIAMOND

While LILIANG DIAMOND itself did not achieve a limit‑up, the overall positive sentiment in the synthetic diamond and super‑hard materials segment is likely to benefit the company. The export‑control policy may increase demand for domestically produced diamond‑based products, potentially improving revenue prospects. Investors should monitor the company’s earnings releases and any announcements related to production capacity or new product lines that could capitalize on the tightened global supply.

Summary

The 14 October 2025 trading day was marked by a rise in the synthetic diamond and super‑hard materials themes, driven in part by new export controls that favor domestic producers. LILIANG DIAMOND, with a market cap of approximately 9.3 billion CNY and a price‑earnings ratio above 115, did not hit a trading limit but remains within a sector experiencing strong gains. The company’s future performance will depend on its ability to leverage sector‑wide demand shifts and its operational execution.
