- The report discusses a **quantitative timing model based on volume signals**, which indicates a "bullish" view for all major indices except the ChiNext Index as of January 23, 2026[30][31][33] - A **momentum sentiment indicator** is introduced, calculated as the proportion of stocks in the CSI 300 Index with positive returns over the past N days. The indicator is smoothed using two moving averages (N1=50, N2=35). When the short-term average exceeds the long-term average, it signals a bullish market sentiment[32][34][36] - The **moving average sentiment indicator** is based on the eight moving averages (8, 13, 21, 34, 55, 89, 144, 233). The indicator assigns values of -1, 0, or 1 based on the position of the current price relative to these moving averages. A value greater than 5 indicates a bullish signal for the CSI 300 Index[40][44] - The **cross-sectional volatility factor** is analyzed, showing that the CSI 300 Index's cross-sectional volatility increased week-over-week, indicating an improved short-term alpha environment. Conversely, the cross-sectional volatility for the CSI 500 and CSI 1000 indices decreased, suggesting a deteriorated alpha environment[45][46] - The **time-series volatility factor** is also evaluated, revealing that the time-series volatility for the CSI 300, CSI 500, and CSI 1000 indices decreased week-over-week, indicating a worsening alpha environment. Over the past quarter, the CSI 300 Index's volatility was in the lower range of the past six months, while the CSI 500 and CSI 1000 indices were in the middle range[46][49]

Core Viewpoint - The article emphasizes the AIPCB wave and highlights the investment opportunities arising from the upgrade of M9 materials, focusing on four main lines of development [1]. Group 1: Low Dielectric Electronic Fabrics - The transition from LDK to second-generation fabrics is underway, with M9 paired with Q fabrics evolving towards third-generation products [17]. - The market for low dielectric electronic fabrics is expected to grow rapidly, driven by AI server demand, with a projected compound annual growth rate of 23.8% from 2024 to 2033 [20][23]. Group 2: Electronic Resins - The use of hydrocarbon resins in M9 is expected to increase significantly, with a ratio of hydrocarbon resins to PPO rising to 2:1, enhancing the value of materials [31][34]. - New types of resins are becoming mainstream, with hydrocarbon resins being the preferred choice for next-generation high-frequency CCLs [31][39]. Group 3: Fillers - The proportion of spherical silica micro-powder in M9 is expected to increase significantly, with high-performance spherical silica micro-powder filling ratios expanding to over 40% [36][40]. - Liquid-phase preparation methods for silica are becoming the industry standard, meeting the requirements for M7 and above [40]. Group 4: Other Upstream PCB Materials - Attention is drawn to electronic-grade fluorinated copper powder and PCB-specific electronic chemicals, which are essential for the upgrade trends in high-end PCBs [3][43]. - The supply of high-end materials, including Low Dk electronic fabrics and HVLP copper foil, is facing shortages, with major manufacturers accelerating production to meet demand [7][29]. Group 5: Market Performance - The demand for high-end CCL driven by AI is accelerating the upgrade of upstream materials, with significant performance improvements observed in various AIPCB sub-sectors since mid-2025 [5][8]. - The average increase in AIPCB sub-sector indices from May to August 2025 shows substantial growth, particularly in electronic fabrics and copper foil [6].
