The average shipment rate has decreased to 44.6% [21]. - **Glass**: The average price of float glass is reported at 1163.9 CNY/ton, reflecting a weekly increase of 16.0 CNY/ton but a year-on-year decrease of 254.7 CNY/ton [48].

Summary of Key Points from Conference Call Records Industry Overview - The focus is on the non-ferrous metals industry, particularly copper, aluminum, and the construction materials sector, as well as the gold market and its outlook [1][2][4][5][6][9]. Non-Ferrous Metals - **Copper Market**: Short-term price surge due to U.S. tariff expectations leading to an expanded price gap between LME and COMEX. The U.S. market pricing is deviating from fundamentals. By 2026, the U.S. siphoning effect may create tight inventory risks in non-U.S. regions, but a return to fundamental pricing could occur if LME experiences warehouse congestion or tariff expectations decrease, leading to potential oversupply risks [1][5]. - **Aluminum Market**: Prices are expected to follow copper trends, with global supply affected by electricity shortages. Domestic production has peaked, and high overseas energy costs, along with investment cycle constraints, will likely lead to a decline in supply growth from 2025 to 2030. A bull market is needed to strengthen price incentives, with occasional events also pushing prices up [1][5]. Gold Market - The outlook for the gold market remains optimistic, driven by central bank purchases, ETF investments, and potential gold tokenization. Gold prices are expected to rise significantly by 2026, with current stock valuations between 10 to 13 times earnings being attractive [1][4]. Construction Materials - The construction materials sector is experiencing supply contraction under profit pressure. Recommendations include focusing on consumer building materials and leading fiberglass companies. Differentiation in product offerings is allowing some companies to achieve excess profits, with leading float glass companies expected to balance supply through self-initiated repairs, aiding profit recovery [1][6][7][8]. Fiberglass Industry - Demand for fiberglass is projected to grow in the high single digits, with approximately 400,000 tons of new domestic supply expected next year, while about 100,000 tons of overseas capacity will exit annually. High-end products remain scarce, and leading companies like China National Building Material and China Jushi are recommended [3][9]. Cement Industry - The cement industry is controlling supply through production limits and peak-shifting measures. By the end of 2025, a net reduction of over 50 million tons of capacity is anticipated, with a potential overall capacity reduction of over 10% in 2026 if monitoring and enforcement measures are effective. The industry is expected to see a moderate recovery in profit margins [11]. Phosphate and Potash Markets - Phosphate demand is significantly driven by the growth in energy storage, with total demand for power and storage batteries expected to reach 450 to 500 GWh by 2026, translating to a demand for 4.3 to 5 million tons of phosphate rock. The potash market is also expected to see stable growth, with limited new supply and high import dependence from China, leading to favorable price expectations [22][24]. Chemical Industry - The chemical industry is currently at a cyclical low but is expected to enter an upward phase starting late 2025. Industry self-discipline measures are enhancing price elasticity, with recent price increases observed in various chemical products [25][26][27]. Investment Opportunities - Recommended investment opportunities include potassium and phosphorus fertilizers, which are supported by strong fundamentals and global agricultural and renewable energy growth. Related fine chemicals like refined phosphoric acid and yellow phosphorus also show significant investment potential due to their wide applications [28].

Group 1: Optical Modules - The optical module industry is experiencing the highest growth and performance realization among AI hardware this year, driven by high verification barriers for North American CSP tech giants and increasing demand due to the acceleration of supernode technology [2][4] - The average ratio of optical modules to GPUs is continuously increasing, with demand for 800G and 1.6T optical modules being revised upwards, indicating a strong upward resonance in demand [2][4] - By 2026, the demand for 1.6T optical modules is expected to exceed 30 million units, with an average price of $900-1000 per unit, while high-end EML optical chips are projected to face a 25-30% supply shortage [4][5] Group 2: Liquid Cooling - The liquid cooling industry has seen fluctuating trends this year, with initial enthusiasm dampened by low penetration rates, followed by a resurgence in August and significant breakthroughs in November [5][9] - The demand for liquid cooling in North America is expected to expand rapidly by 2026, with penetration rates in the NVIDIA ecosystem projected to rise from 20-30% to over 80-90% [7][9] - A leading domestic manufacturer is anticipated to capture a market share of 13-17% in North America by 2026, with Google expected to implement liquid cooling solutions for over 200,000 TPU V7 chips, creating a market space exceeding $24-28 billion [9][10] Group 3: AI PCB - The AI PCB industry is thriving, with companies like Shenghong, Huidian, and Shengyi achieving performance realization in North America, despite some quarterly fluctuations [10][12] - The supply side is seeing an increase in product value and manufacturing difficulty due to upgrades in customer chips and cabinet solutions, leading to a marginal differentiation in the supply landscape [10][12] - By 2026, the introduction of orthogonal backplanes is expected to significantly increase unit value, with M9 material processing anticipated to break through, although mass production is expected to ramp up in 2027 [12][13] Group 4: Server Power Supply - The server power supply market has shown similar trends to liquid cooling, with initial excitement followed by a divergence in performance among manufacturers [13][14] - The supply side is dominated by Taiwanese manufacturers, with a high concentration of market share, while domestic manufacturers are expected to make significant breakthroughs in North America by 2026 [14][15] - The adoption of HVDC technology is projected to replace traditional UPS solutions, with an expected market scale exceeding $20-30 billion by 2026 [15]
