Market Overview - On October 20, A-shares saw a collective rise in the three major indices, with the Shanghai Composite Index up by 0.63%, the Shenzhen Component Index up by 0.98%, and the ChiNext Index up by 1.98%. The North Stock 50 Index decreased by 0.25%. The total trading volume in the Shanghai and Shenzhen markets was 1.7513 trillion yuan, a decrease of 203.1 billion yuan from the previous day. Over 4,000 stocks in the market rose [1]. Sector Performance - The cultivated diamond sector led the gains, rising by 6.69% by the end of the day, with multiple stocks in the sector increasing by over 10%. This surge followed an announcement from Power Diamond about successfully cultivating a 156.47-carat diamond, which is now the largest known single crystal diamond produced artificially, surpassing the previous record of 150.42 carats set by Meylor Global in 2022 [2]. Company Insights - Power Diamond is a high-tech enterprise specializing in the research, production, and sales of synthetic diamond products, including cultivated diamonds, diamond single crystals, and diamond micropowder. The company highlights that with the rise of 5G, 6G, AI, and quantum computing, the increasing heat density in chip performance has made heat dissipation a critical issue. Diamonds, with thermal conductivity five times that of copper and over ten times that of silicon, are considered the ideal material for heat dissipation [3]. Market Sentiment and Future Outlook - Huatai Securities suggests that market sentiment is approaching a neutral level, indicating that after a reasonable cooling of capital indicators, market sentiment may revert to a more favorable range. CITIC Construction believes that the logic of a bull market remains intact, supported by capital market reforms and structural prosperity, with limited downward adjustments expected. China Galaxy sees short-term adjustments as opportunities for investors, with the ongoing trend of "deposit migration" likely to provide long-term incremental capital for the A-share market. The acceleration of capital into the equity market is anticipated, supported by the Federal Reserve's interest rate cuts and strategic planning under the "14th Five-Year Plan" [4].
