Incorporate two short-term factors: - **Reversal Factor**: Accounts for short-term price reversals - **Profitability Factor**: Reflects the company's earnings performance[5][16] **Factor Evaluation**: The factor effectively identifies high-dividend stocks and serves as a reliable input for portfolio construction[16] - **Factor Name**: Red Dividend Timing Framework (Composite Signal) **Factor Construction Idea**: Combines multiple single-factor signals to assess the market's outlook on dividend stocks[25][28] **Factor Construction Process**: 1. Evaluate five single-factor signals: - **Inflation**: PPI YoY (High/Low) - **Liquidity**: M2 YoY (High/Low) - **M1-M2 Gap**: Scissors Difference (High/Low) - **Interest Rate**: US 10-Year Treasury Yield (High/Low) - **Market Sentiment**: Dividend Stock Turnover Ratio (Up/Down)[28] 2. Assign binary signals (1 for bullish, 0 for bearish) to each factor 3. Aggregate the signals into a composite indicator[28] **Factor Evaluation**: The framework provides a systematic approach to timing dividend stock investments, though the September 2025 signal suggests a cautious stance[25][28] Factor Backtesting Results - **Expected Dividend Yield Factor**: - August 2025 Portfolio Average Return: 5.69% - Excess Return (vs CSI 300 Index): -4.80% - Excess Return (vs CSI Dividend Index): +4.70%[5][16] - **Red Dividend Timing Framework (Composite Signal)**: - Latest Signal (September 2025): 0 (Neutral)[25][28]
