Summary of Conference Call Notes Industry Overview - The discussion revolves around the Chinese stock market, specifically the Shanghai Composite Index, and its potential movements influenced by liquidity and fundamental factors [1][2][3]. Key Points and Arguments Market Types - Three types of bull markets are identified: liquidity bull, fundamental bull, and new-old momentum transformation bull [2][3]. - The liquidity bull is driven by funds transitioning from bonds to stocks, focusing on valuation and fundamentals, which limits the upward potential of indices like the Shanghai Composite [3]. - The fundamental bull relies on domestic profit recovery and external economic expansion, particularly observing PMI data from Japan and Europe, as well as China's export figures [4][5]. Market Predictions - If the Federal Reserve lowers interest rates in September and expands fiscal spending, global PMI could expand, potentially allowing the Shanghai Composite to break through the 4,000-point mark [5][7]. - The expected profit growth rate could recover to 10-15% if a fundamental bull market is confirmed by the end of the year [7]. Economic Dynamics - The transformation of new and old economic drivers is analyzed through retail sales recovery, export resilience, and real estate recovery, proposing a four-stage pricing framework [6][10]. - Despite a decline in exports to the U.S., China is rapidly shifting its exports to Europe and other regions, which may support economic growth in the second half of the year [11][12]. Fund Management Strategies - Public funds are advised to focus on institutional themes while avoiding heavy investments in large-cap stocks, instead targeting smaller, niche sectors that are experiencing growth [16]. - The current market environment suggests that smaller funds are performing better, and there is a notable trend favoring micro-cap stocks [15][16]. Global Economic Context - The U.S. economic data and Federal Reserve policy changes are critical, with mixed signals regarding interest rate cuts and inflation expectations impacting market sentiment [17][19]. - The potential for a recession or stagnation in the U.S. economy could influence global markets, including the Chinese stock market [18][19]. Additional Important Insights - The new-old momentum transformation framework is expected to play a significant role in market pricing by 2026, with new economic sectors like AI and innovative pharmaceuticals gaining prominence while traditional sectors stabilize [9][10]. - The relationship between China and the U.S. and Europe remains complex, with potential risks that could affect China's export capabilities and overall economic performance [11][12].

Quantitative Models and Construction Methods 1. Model Name: Diffusion Index Model - **Model Construction Idea**: The model is used to monitor the critical points of trend changes in the micro-cap stock index by analyzing the distribution of stock price movements over a specific time window[6][38]. - **Model Construction Process**: The model calculates the diffusion index based on the relative price changes of all constituent stocks in the micro-cap stock index over a given time window. For example, if the horizontal axis is 0.95 and the vertical axis is 15 days, the value of 0.51 indicates that after 5 days (review period from T=20 to T=15), if all stocks in the micro-cap index drop by 5%, the diffusion index value is 0.51[38]. - Current diffusion index value: 0.87 (horizontal axis = 20, vertical axis = 1.00)[38]. - **Model Evaluation**: The model shows that the current distribution is relatively uniform, indicating that the time window has little impact, and the main influence comes from the spatial distribution[38]. 2. Model Name: First Threshold Method (Left-Side Trading) - **Model Construction Idea**: This method triggers a sell signal when the diffusion index reaches a predefined threshold[6][42]. - **Model Construction Process**: - On May 8, 2025, the model triggered a sell signal when the diffusion index reached 0.9850[42]. 3. Model Name: Delayed Threshold Method (Right-Side Trading) - **Model Construction Idea**: Similar to the first threshold method but with a delayed response to confirm the trend[6][44]. - **Model Construction Process**: - On May 15, 2025, the model triggered a sell signal when the diffusion index reached 0.8975[46]. 4. Model Name: Dual Moving Average Method (Adaptive Trading) - **Model Construction Idea**: This method uses two moving averages to adaptively identify trading signals based on the diffusion index[6][47]. - **Model Construction Process**: - On August 4, 2025, the model issued a sell signal based on the dual moving average strategy[47]. --- Model Backtesting Results 1. Diffusion Index Model - Current diffusion index value: 0.87[38]. 2. First Threshold Method - Triggered sell signal at diffusion index value: 0.9850[42]. 3. Delayed Threshold Method - Triggered sell signal at diffusion index value: 0.8975[46]. 4. Dual Moving Average Method - Triggered sell signal on August 4, 2025[47]. --- Quantitative Factors and Construction Methods 1.
