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 [5][39] - **Model Construction Process**: The diffusion index is calculated based on the relative price changes of constituent stocks over a retrospective or forward-looking window. For example, if the horizontal axis is 0.95 and the vertical axis is 15 days, the value of 0.31 indicates that if all constituent stocks drop by 5% after 5 days, the diffusion index value is 0.31.

Model Name: Small-Cap Low-Volatility 50 Strategy - **Model Construction Idea**: This strategy selects 50 stocks with small market capitalization and low volatility from the micro-cap stock index, rebalancing every two weeks [7][36] - **Model Construction Process**: - Select stocks with the smallest market capitalization and lowest volatility from the micro-cap index - Rebalance the portfolio bi-weekly - Benchmark: Wind Micro-Cap Stock Index (8841431.WI) - Transaction cost: 0.3% on both sides [7][36] - **Model Evaluation**: The strategy demonstrates strong performance in 2025 but underperformed in 2024, indicating sensitivity to market conditions [7][36] --- Model Backtesting Results 1. Diffusion Index Model - **First Threshold Method**: Triggered sell signal at 0.9850 on May 8, 2025 [43] - **Delayed Threshold Method**: Triggered sell signal at 0.8975 on May 15, 2025 [47] - **Double Moving Average Method**: Triggered buy signal on July 3, 2025 [48] 2.

本周，大盘再创本轮行情的新高。不过，就在大家对行情寄予更高期望之时，上证指数却迎来了连 续两天的调整。周五收盘后，美国非农数据不及预期，导致美股大幅调整。 大盘已调整两天，外围市场又传来利空，下周还会延续调整吗？8月份，应该注意什么？今天，达 哥和牛博士就大家关心的问题进行讨论。 不过，对身处其中的人，情况则不同。在这两波回调中，当时不少人认为"牛没了"，尤其是出现了 日K线5连阴的时候。因此，对于本轮回调，我认为，可能会让一些人对牛市的信仰产生动摇。 牛博士：达哥，你好，又到了我们周末聊行情的时间。你在上周日说，从历史来看，在突破重要压 力位之前会有一波回调。本周大盘已经回调了两个交易日，这是否就是你说的回调一波的情况？美国非 农数据不及预期，导致美股大幅调整，这个消息是否会加剧A股的调整进程？对于8月份的行情，你又 是如何看待的？ 道达：美国7月非农新增就业人数骤降至7.3万人，创下最近9个月以来的最低纪录，而市场预期是 10.4万人。另外，5月和6月的非农新增就业人数被大幅下修，由原先的14.4万、14.7万分别修正为1.9 万、1.4万。经过此次修正，5月和6月的新增就业减少了25.8万。 这个消息出 ...

Quantitative Models and Construction Methods - **Model Name**: Diffusion Index Model **Construction Idea**: The model monitors the future critical points of diffusion index changes to predict market trends[40][41] **Construction Process**: 1. Define the horizontal axis as the relative price change of stocks in the index, ranging from +10% to -10% 2. Define the vertical axis as the review period length (T days) or future period length (N days), where T ranges from 20 to 10 days, and N = 20 - T 3. Calculate the diffusion index value for each combination of horizontal and vertical axis values 4. Example: For N=5 days and T=15 days, if all stocks drop by 5%, the diffusion index value is 0.51[40] **Evaluation**: The model indicates that current trends are driven by leading stocks rather than bottom stock rotation, suggesting the weakening of reversal factors and strengthening of fundamental factors[41] - **Model Name**: First Threshold Method (Left-Side Trading) **Construction Idea**: This method triggers signals based on predefined threshold values[44] **Construction Process**: 1. Monitor the diffusion index value daily 2. Trigger a signal when the index reaches a specific threshold 3. Example: On May 8, 2025, the diffusion index value of 0.9850 triggered a sell signal[44] **Evaluation**: Provides early warning signals for market reversals[44] - **Model Name**: Delayed Threshold Method (Right-Side Trading) **Construction Idea**: Similar to the first threshold method but with delayed signal generation[46][48] **Construction Process**: 1. Monitor the diffusion index value daily 2. Trigger a signal when the index reaches a delayed threshold 3. Example: On May 15, 2025, the diffusion index value of 0.8975 triggered a sell signal[48] **Evaluation**: Offers a more conservative approach compared to the first threshold method[48] - **Model Name**: Dual Moving Average Method (Adaptive Trading) **Construction Idea**: Uses moving averages to adapt to market trends[49] **Construction Process**: 1. Calculate short-term and long-term moving averages of the diffusion index 2. Generate buy or sell signals based on the crossover of these averages 3. Example: On July 3, 2025, the method issued a buy signal[49] **Evaluation**: Effective in capturing trend reversals during adaptive market conditions[49] Model Backtesting Results - **Diffusion Index Model**: Current value is 0.89, showing an increasing trend at the bottom level[40][41] - **First Threshold Method**: Triggered a sell signal at 0.9850 on May 8, 2025[44] - **Delayed Threshold Method**: Triggered a sell signal at 0.8975 on May 15, 2025[48] - **Dual Moving Average Method**: Triggered a buy signal on July 3, 2025[49] Quantitative Factors and Construction Methods - **Factor Name**: Illiquidity Factor **Construction Idea**: Measures the impact of stock liquidity on returns[4][35] **Construction Process**: 1.

Calculate the quarterly net profit growth rate for each stock 2. Rank stocks based on growth rates 3. Example: Weekly rank IC is 0.062, historical average is 0.02[4][35] **Evaluation**: Moderate performance, slightly above historical averages[4][35] - **Factor Name**: Unadjusted Stock Price Factor **Construction Idea**: Uses raw stock prices without adjustments for splits or dividends[4][35] **Construction Process**: 1. Rank stocks based on their unadjusted prices 2. Calculate the rank IC for the factor 3. Example: Weekly rank IC is 0.055, historical average is -0.016[4][35] **Evaluation**: Positive performance, reversing historical negative trends[4][35] - **Factor Name**: Dividend Yield Factor **Construction Idea**: Measures the dividend yield of stocks[4][35] **Construction Process**: 1. Calculate the dividend yield for each stock 2. Rank stocks based on yield values 3. Example: Weekly rank IC is 0.046, historical average is 0.021[4][35] **Evaluation**: Consistent performance, slightly above historical averages[4][35] - **Factor Name**: PB Reciprocal Factor **Construction Idea**: Uses the reciprocal of the price-to-book ratio[4][35] **Construction Process**: 1.
