Core Viewpoint - The high-performance electronic fabric market is experiencing a supply-demand imbalance due to strong demand from AI servers and high-frequency communication sectors, leading to price increases for related products [1][2]. Supply and Demand - Strong demand for AI is causing a short-term mismatch between the production capacity of high-performance electronic fabrics and market needs [2]. - The core raw material for high-performance electronic fabrics is high-performance glass fiber yarn, which has high technical barriers to production, with only a few manufacturers in Japan, the United States, and Taiwan capable of mass production [2]. Price Increase - The tightening of production capacity is driving expectations for price increases in electronic yarn products. For instance, Nittobo, a global leader in electronic yarn, announced a 20% price increase for its glass fiber products starting August 1 [3]. - According to Honghe Technology, the average selling price of electronic-grade glass fiber fabric is projected to reach 4.81 yuan per square meter in the 2025 mid-year report, reflecting a year-on-year increase of 1.15 yuan per meter, with prices rising for four consecutive quarters [3]. Company Developments - China National Glass Fiber is actively advancing the development of low-dielectric and low-expansion products, with downstream certifications progressing rapidly. The ongoing demand from AI is expected to further expand the high-performance electronic fabric market [4]. Market Outlook - The storage market is showing signs of recovery, with South Korea's storage chip export value increasing by 20.7% year-on-year in Q2 2025, and average prices rising by 0.7% year-on-year. The average price of storage chips has rebounded to 2022 levels, indicating a potential new cycle in the storage market [5]. Investment Recommendations - The electronic industry maintains a "buy" rating, with a focus on upstream materials in the AIPCB sector. Companies to watch include Honghe Technology, Tongguan Copper Foil, Defu Technology, Dongcai Technology, Shengquan Group, Tiancheng Technology, Lianrui New Materials, and Jiangnan New Materials [6].

Core Viewpoint - The recent sharp decline in the A-share market, particularly the 2.85% drop in the ChiNext Index, is not indicative of the end of a bull market but rather a typical shakeout behavior during an upward trend, suggesting a potential for short-term rebound [1][4]. Market Adjustment Factors - The market adjustment on September 2 was influenced by multiple factors, including technical pressure from accumulated profit-taking after a prolonged upward trend since April [3]. - There was a significant rotation of funds from high-valuation growth sectors, particularly in technology, to undervalued defensive sectors such as banking and utilities, amplifying market volatility [3]. - The negative sentiment from the substantial decline in U.S. tech stocks and the market's cautious stance ahead of the Federal Reserve's September meeting contributed to the adjustment [3]. Long-term Market Support - Despite the recent downturn, the core logic supporting a medium to long-term positive outlook for the market remains intact, driven by ongoing policies in sectors like "Artificial Intelligence+" and measures aimed at stabilizing growth and boosting consumption [5]. - The rapid decline is seen as a quick release of risks, effectively digesting profit-taking and eliminating localized bubbles, which can accumulate strength for future upward movement [5]. Short-term Market Outlook - In the short term, there is potential for a technical rebound following the recent sharp decline, supported by ample policy tools for growth stabilization and expectations of possible interest rate cuts [7]. - The anticipated easing of the Federal Reserve's monetary policy and a weaker dollar may enhance the attractiveness of RMB assets, potentially leading to a continued inflow of northbound capital [7]. - The significant trading volume of 2.87 trillion yuan during the decline indicates a release of short-term selling pressure, with stabilization in key sectors providing support for the market [7]. - The emotional release from the sharp drop may lead to a stabilization of market sentiment, allowing for a recovery of quality stocks that were oversold [7].

Quantitative Models and Construction Valuation Spread-Based Style Factor Model - **Model Name**: Valuation Spread-Based Style Factor Model - **Model Construction Idea**: This model uses the valuation spread between long and short groups of a factor (e.g., BP) to construct a style factor's odds indicator. It emphasizes a "left-side" signal characteristic, meaning "buy when it drops significantly, sell when it rises significantly" [7][11] - **Model Construction Process**: 1. Select a factor and sort stocks by factor values into five groups (industry-neutral, grouping within each industry and then merging) to determine the long and short groups [11] 2. Calculate the median log(BP) for the long and short groups, where log transformation ensures BP follows a normal distribution [11] 3. Compute the raw valuation spread as the difference between the median log(BP) of the long group and the short group [11] 4. Standardize the raw valuation spread using a rolling six-year z-score [11] - **Model Evaluation**: The valuation spread demonstrates a certain degree of differentiation in predicting the future one-year returns of style factors. It is more suitable for identifying left-side signals [7] --- Quantitative Factors and Construction Dividend Yield Factor - **Factor Name**: Dividend Yield Factor - **Factor Construction Idea**: Represents the valuation spread of the dividend yield factor, indicating the relative attractiveness of value-oriented stocks [14] - **Factor Construction Process**: Constructed using the valuation spread methodology described above, with the dividend yield as the underlying factor [14] PB Factor - **Factor Name**: PB Factor - **Factor Construction Idea**: Represents the valuation spread of the price-to-book ratio (PB), reflecting the relative valuation of value-oriented stocks [14] - **Factor Construction Process**: Constructed using the valuation spread methodology described above, with PB as the underlying factor [14] PE Factor - **Factor Name**: PE Factor - **Factor Construction Idea**: Represents the valuation spread of the price-to-earnings ratio (PE), indicating the relative valuation of value-oriented stocks [14] - **Factor Construction Process**: Constructed using the valuation spread methodology described above, with PE as the underlying factor [14] Quality Factor - **Factor Name**: Quality Factor - **Factor Construction Idea**: Represents the valuation spread of the ROE factor, typically associated with "core assets" like high-quality companies [20] - **Factor Construction Process**: Constructed using the valuation spread methodology described above, with ROE as the underlying factor [20] Low Volatility Factor - **Factor Name**: Low Volatility Factor - **Factor Construction Idea**: Represents the valuation spread of low-volatility stocks, often linked to "stable assets" [20] - **Factor Construction Process**: Constructed using the valuation spread methodology described above, with volatility as the underlying factor [20] Momentum Factor - **Factor Name**: Momentum Factor - **Factor Construction Idea**: Represents the valuation spread of momentum stocks, often associated with stocks heavily held by public funds [20] - **Factor Construction Process**: Constructed using the valuation spread methodology described above, with momentum as the underlying factor [20] --- Backtesting Results of Factors Valuation Spread-Based Style Factor Model - **Odds Indicator**: Demonstrates differentiation in predicting future one-year returns of style factors, with higher odds indicating better opportunities [7][8] Dividend Yield Factor - **Odds**: 0.47 standard deviations, categorized as medium odds [14] PB Factor - **Odds**: 0.63 standard deviations, categorized as medium-high odds [14] PE Factor - **Odds**: 0.82 standard deviations, categorized as medium-high odds [14] Quality Factor - **Odds**: 1.17 standard deviations, categorized as high odds [20] Low Volatility Factor - **Odds**: 1.75 standard deviations, categorized as very high odds [20] Momentum Factor - **Odds**: -1.36 standard deviations, categorized as low odds [20]
