Core Viewpoint - The main investment logic in A-shares for 2026 is centered around price increases, where rising prices of certain goods and services are expected to lead to higher stock prices for related companies, as increased selling prices enhance profitability and provide support for stock prices [1][10]. Price Increase Concept - Market expert Peng Zu has identified 2026 as a "big year" for price increases, emphasizing the significance of this trend in investment strategies [2][11]. - The most resilient sectors benefiting from price increases include computing power, cloud services, and optical fiber, all driven by the demand surge from AI applications [3][12]. - Year-to-date, stocks related to computing power and cloud services, such as Wangsu Technology, have seen significant gains, with an increase of over 110% since the beginning of the year [3][13]. Optical Fiber Sector - The optical fiber sector has also experienced substantial price increases, with monthly price rises exceeding 75% since the beginning of 2026, reaching an average price of over 40 yuan per core kilometer, with some manufacturers quoting prices as high as 50 yuan per core kilometer [3][13]. - Companies like Yangtze Optical Fibre and Hengtong Optic-Electric have seen their stock prices rise significantly due to these trends [3][13]. Chemical Sector - The chemical sector has emerged as a strong performer, with companies like Runtu Co., Ltd. seeing their stock prices nearly double since January 19, 2026, driven by rising prices of key products [4][14]. - Baichuan Co., Ltd. has also reported significant price increases for its products, with TMP prices soaring from over 8,000 yuan per ton at the end of 2025 to 15,000 yuan per ton by February 2026, enhancing profit expectations [5][15]. Demand and Supply Dynamics - The recovery in downstream demand from sectors like real estate and new energy is driving increased demand for chemical raw materials, while industry capacity reductions and rising raw material costs are forcing collective price increases [6][14]. - The ongoing supply-demand imbalance in sectors such as computing power, cloud services, and optical fiber is expected to persist, supporting the price increase logic [8][17]. Institutional Investment Trends - Institutional investors are likely to remain engaged, with expectations of continued accumulation of leading stocks in the computing power and optical fiber sectors, as they have shown confidence in the sustainability of price increases [9][18]. - Following the Spring Festival, there is an anticipated influx of capital into A-shares, particularly favoring sectors with strong price increase narratives [9][18]. Policy and Industry Support - Post-Spring Festival, policies supporting the "East Data West Computing" project and AI industry are expected to further stimulate demand in computing power, cloud services, and optical fiber sectors [9][18].
