Comments: Following the rise of graphene, hexagonal boron nitride is expected to play a significant role in the future semiconductor industry. In the A-share market, companies involved in super-hard materials such as Yu Diamond (300064), Sifangda (300179), and Yellow River Cyclone (600172) may attract attention as potential investment opportunities.
Yu Diamond: A diamond company with a potentially undervalued stock price
Investment Highlights:
    For 2012, the company's performance fell short of expectations, with earnings per share dropping significantly below the previous 4 cents. This was primarily due to three factors: 1) The micronized powder business did not deliver the anticipated profit growth, contributing less than our forecasted 1 cent. However, after acquiring the Micronized Joint Venture in Q4 2011 and completing relocations and tariff optimizations, the company laid a solid foundation for a recovery in 2013. 2) A slowdown in fixed asset investment led to lower prices for low-grade single crystal products, which affected overall profitability. 3) Equity incentive expenses amounted to 10.67 million yuan, impacting earnings by nearly 2 cents. These costs will be amortized over time, with 7.34 million in 2013 and 2.66 million in 2014, reducing their impact gradually.
    Looking ahead at the main business in 2013: 1) Single crystal production capacity continues to grow, but the top three suppliers still dominate the mid-to-high-end segment. Prices for low-grade broken materials have stabilized, and with the completion of the 1.02 billion carat project, production is expected to increase by 30%. 2) The micronized powder business has shown strong signs of improvement after one year of restructuring. The company is now focusing on expanding its micro-powder operations, which are used in precision grinding and functional applications based on thermal and optical properties—offering great long-term potential. 3) The wire saw business has been temporarily paused due to challenges in the photovoltaic sector, but with signs of improvement in the industry and supportive policies, the company plans to adjust its strategy accordingly.
    In the recent market rebound, the company’s stock has only risen about 20% from its lowest point. As a functional new material company with strong earnings potential, the stock remains in a relatively undervalued range.
Investment Recommendation: The projected EPS for 2012–2014 is 0.25, 0.33, and 0.42 yuan respectively. With a current P/E ratio of 17 times 2013 earnings, we maintain a "Strong Buy" rating.
Risk Warning: Unexpected slowdown in macroeconomic growth could negatively affect the company's performance.
Boron nitride hand-held graphite thin superhard material breakthrough
Abstract Researchers from the Massachusetts Institute of Technology have developed a single-atom thick hexagonal boron nitride, a material that closely resembles graphene in both thickness and physical properties. By placing a layer of graphene on top of this material, they created a hybrid structure that retains the excellent electrical conductivity of graphene while introducing an energy band gap—making it suitable for building transistors. This breakthrough is seen as a major step forward in the development of next-generation electronic materials.
