**Investment Opportunities** 1. **LNG Supply Constraints May Persist Until End-2027** Reports indicate that nearly 20% of LNG supply has exited the market due to disruptions in shipping through the Strait of Hormuz since early March, causing sharp price increases in major import regions. The International Energy Agency's latest quarterly gas market report suggests the crisis could permanently alter the LNG outlook, with cumulative supply reductions of about 120 billion cubic meters expected between 2026 and 2030. Supply tightness, exacerbated by Middle East conflict-related logistical issues and infrastructure damage, may last until the end of 2027.

2. **Diamond's Role in AI-Era Advanced Manufacturing** Domestic diamond producers have recently raised prices for industrial diamond and lab-grown diamond rough by 10-15%. This reflects not only improved supply-demand dynamics but also growing expectations for diamond's application as a new material amid chip integration trends. Analysis suggests synthetic diamond, with its extreme thermal conductivity and hardness, is penetrating thermal management in computing systems and high-end manufacturing. The industry is transitioning from traditional industrial consumables and consumer alternatives to a key material for advanced manufacturing in the AI era. Companies involved in diamond materials, applications, and production equipment may benefit from the industrialization of diamond heat dissipation and diamond drill bits. Assuming diamond heat sinks capture 8-10% of the value in AI chips with a 20-30% penetration rate, the market size could reach 48-90 billion yuan by 2030.
