Core Viewpoints - The current adjustment is characterized as a "doubtful bull market level," indicating that the major trends in the AI industry chain have not ended, although there are short-term fluctuations and a temporary lack of cost-effectiveness in large trends. This situation resembles historical patterns observed in early 2014, early 2018, and early 2021 [1][3][5] - The "two-stage bull market theory" remains unchanged, suggesting that the transition from Bull Market 1.0 to 2.0 is a typical feature of the A-share bull market cycle. The transition period is expected to occur in the first half of 2026, with a full bull market potentially starting in the second half of 2026 [1][5][6] Summary by Sections Adjustment Phase - The adjustment phase is seen as a "doubtful bull market level," where the AI industry chain is experiencing a lack of cost-effectiveness, leading to a market correction. Historical experiences indicate that such adjustments are typical and often occur in quarterly cycles [3][4] - The current market conditions show that the implied equity risk premium (ERP) in sectors like telecommunications and electronics is still above historical lows, while the price-to-earnings (PE) ratios are at absolute historical highs [3][4] Spring Market Outlook - The spring market is expected to be more promising post-adjustment, with economic growth needing to maintain a high level to achieve the 2035 medium-developed country goal. The third quarter of 2025 showed weak economic performance, and December 2025 is seen as a critical window for laying out economic policies for 2026 [6][7] - The technology sector is anticipated to see a rapid improvement in cost-effectiveness, with institutional investors reducing their technology holdings in the short term. The micro-structural improvements in the technology sector are also expected to play a significant role in the spring market rotation [6][7] 2026 Industry Style and Rhythm Outlook - The transition from Bull Market 1.0 to 2.0 is expected to favor high-dividend defensive stocks. The actual improvement in economic sentiment will catalyze cyclical stocks to lead index breakthroughs, with technology trends and manufacturing global influence being the main themes of the bull market [8] - In the spring of 2026, the early validation of policy bottoms, cyclical price increases, and improved year-on-year PPI expectations will provide a foundation for cyclical assets. Key areas of focus include basic chemicals, industrial technology, innovative pharmaceuticals, and defense industries, with potential rebounds in AI computing power, storage, energy storage, and robotics [8]

Group 1 - The report indicates that the current adjustment phase is characterized as a "doubtful bull market level," with the AI industry chain experiencing a significant trend that has not yet ended, while smaller fluctuations are present and the cost-effectiveness of large trends is temporarily insufficient. This situation resembles historical patterns observed in early 2014 with the ChiNext, early 2018 with food and beverage, and early 2021 with new energy [4][6][7] - The "bull market two-stage theory" remains unchanged, confirming the high-level area of the bull market 1.0 phase. The transition from bull market 1.0 to 2.0 is expected to occur in the first half of 2026, with a focus on the accumulation of conditions for a comprehensive bull market and adjustments in industry trends to digest cost-effectiveness issues [6][7][9] - The report emphasizes that while adjustments are occurring, it is crucial to maintain a firm belief in the bull market. The adjustment phase is seen as a potential bottom, particularly when it aligns with the core track's bull-bear boundary [6][7] Group 2 - The report expresses optimism for the spring market following the adjustment, highlighting that achieving the 2035 medium-developed country goal requires maintaining a high economic growth rate. The economic performance in Q3 2025 was weak, and December 2025 is identified as a critical window for laying out economic policies for 2026, with the possibility of an early verification of the "policy bottom" [7][8] - Two key clues for the spring market are discussed: first, the management's emphasis on economic growth and the potential early verification of the "policy bottom"; second, the mid-term upward trend of the technology industry remains unchanged, with the AI industry still in "stage 3" and moving towards "stage 4," indicating non-linear growth in industry profits [8][9] - The report anticipates that the transition from bull market 1.0 to 2.0 will favor high-dividend defensive strategies, with the actual improvement in economic sentiment catalyzing a breakthrough in cyclical stocks, while the technology industry's trend and global influence of manufacturing will be the main lines of the bull market [9] Group 3 - The report outlines expectations for the 2026 industry style rhythm, indicating that cyclical stocks may serve as the foundational assets for the spring market, with basic chemicals and industrial technology being highlighted as higher elasticity directions. The technology sector is expected to rebound, focusing on innovative pharmaceuticals and national defense industries [9][10] - Specific sectors such as AI computing power, storage, energy storage, and robotics are anticipated to have rebound opportunities in the spring [9][10] - The report includes quantitative sentiment indicators and ETF tracking data, providing insights into market dynamics and investor sentiment [2][17]
