Group 1: Industry Investment Rating - There is no information about the industry investment rating in the report. Group 2: Core Viewpoints - The bond market in the fourth quarter may move in a volatile manner. Short - term bonds have high allocation and trading value, and there is a possibility of an unexpected decline in inter - bank certificate of deposit rates at the end of the year. Long - term bonds have some room for repair due to the expansion of the term spread. Although there are many bullish factors in the bond market in the fourth quarter, redemption pressure persists, and trading should be based on an interval - oscillation strategy. With the increasing expectation of monetary easing, a more optimistic view of the subsequent bond - market situation can be taken [3][10]. - The restart of the central bank's bond purchases in October had a net purchase amount of only 20 billion yuan, lower than market expectations. The restart should be understood more as a signal, and high expectations for the purchase volume should not be held [3][10]. - The key impact on the market lies in whether the central bank will adjust the bond - purchase term to hedge against the potentially concentrated issuance of long - term and ultra - long - term local bonds in November, which may bring significant pressure to the allocation portfolio [4][19]. Group 3: Summary by Directory 1. How to View the Central Bank's Bond - Purchase Scale - **Viewpoint Review**: The bond market in the fourth quarter may move in a volatile way. Short - term bonds have high value, and long - term bonds have repair space. Bullish factors are numerous, but redemption pressure exists. With rising easing expectations, the subsequent bond - market situation can be viewed more optimistically [3][10]. - **Analysis of the Central Bank's Bond - Purchase Scale**: - **From the perspective of liquidity**: The central bank's bond - purchase space comes from the switch between tools. Since the beginning of this year, repurchase and MLF have been the main channels for the central bank to inject medium - and long - term liquidity. The medium - and long - term liquidity injection has been sufficient, especially after the second quarter, so there is no need to rely on the central bank's bond - purchase channel. At the end of the year, the central bank can increase bond purchases to make up for the concentrated maturity of MLF, but the operation space may be within one trillion yuan if mainly relying on bond purchases [10][11][13]. - **From the perspective of the central bank's bond maturity**: The cumulative scale of the central bank's bond purchases in this round should be limited to around one trillion yuan. The restart of bond purchases is a form of "roll - over," and the continuous purchase scale after the restart needs to reach around one trillion yuan to match the maturity volume. Otherwise, it may be a de - facto non - roll - over [15]. - **From the perspective of monthly purchase scale**: To have a relatively neutral impact on the market, the single - period injection scale may be small. If calculated based on a net weekly purchase of 20 billion yuan, the monthly net purchase scale can reach around 100 billion yuan. Concentrated incremental purchases may cause an abnormal decline in short - term Treasury bond yields, which is not what the central bank wants to see [16].

The model uses methods like left-side threshold, right-side threshold, and dual moving average to generate signals - Left-side threshold method triggered an opening signal on September 23, 2025, with a value of 0.0575[43] - Right-side threshold method triggered an opening signal on September 25, 2025, with a value of 0.1825[47] - Dual moving average method provided a bullish signal on October 13, 2025[48] **Evaluation**: The model is effective in identifying high-risk zones and generating trading signals[6][39][48] - **Model Name**: Small Cap Low Volatility 50 Strategy **Construction Idea**: Select 50 stocks with small market capitalization and low volatility from micro-cap stocks[8][34] **Construction Process**: 1. Stocks are selected based on market capitalization and volatility criteria 2. Portfolio is rebalanced bi-weekly 3. Transaction cost is set at 0.3% for both sides 4.

Calculate turnover rate as trading volume divided by total market capitalization over 10 days 2. Rank IC value for the week: 0.099; historical average: -0.059[5][16][32] **Evaluation**: Positive weekly IC indicates good predictive ability[5][16][32] - **Factor Name**: 10-Day Free Float Market Cap Turnover Rate Factor **Construction Idea**: Measure the turnover rate of free-floating market capitalization over 10 days[5][16][32] **Construction Process**: 1. Calculate turnover rate as trading volume divided by free-floating market capitalization over 10 days 2. Rank IC value for the week: 0.098; historical average: -0.061[5][16][32] **Evaluation**: Positive weekly IC suggests strong factor performance[5][16][32] - **Factor Name**: Dividend Yield Factor **Construction Idea**: Measure the dividend yield of stocks[5][16][32] **Construction Process**: 1. Calculate dividend yield as annual dividend divided by stock price 2. Rank IC value for the week: 0.065; historical average: 0.022[5][16][32] **Evaluation**: Positive weekly IC indicates reliable factor performance[5][16][32] Factor Backtesting Results - **Free Float Ratio Factor**: Weekly IC: 0.108; historical average: -0.012[5][16][32] - **Leverage Factor**: Weekly IC: 0.104; historical average: -0.006[5][16][32] - **10-Day Total Market Cap Turnover Rate Factor**: Weekly IC: 0.099; historical average: -0.059[5][16][32] - **10-Day Free Float Market Cap Turnover Rate Factor**: Weekly IC: 0.098; historical average: -0.061[5][16][32] - **Dividend Yield Factor**: Weekly IC: 0.065; historical average: 0.022[5][16][32]
