Quantitative Models and Construction Methods 1. Model Name: Dividend Forecast Model - **Model Construction Idea**: The model aims to predict the impact of dividends on index futures contracts by estimating the dividend points based on historical and current financial data of index constituent stocks[7][18][21] - **Model Construction Process**: 1. **Estimate Net Profit**: Use annual reports, earnings forecasts, and other financial disclosures to estimate the net profit of constituent stocks[19][21] 2. **Calculate Pre-Tax Dividend Total**: Assume a constant dividend payout ratio (dividend amount/net profit) to calculate the pre-tax dividend total for each stock[21][22] 3. **Impact on Index**: - Calculate the dividend yield: $$\text{Dividend Yield} = \frac{\text{Post-Tax Dividend Total}}{\text{Latest Market Value}}$$ - Calculate the dividend points' impact on the index: $$\text{Dividend Points Impact (\%)} = \text{Stock Weight} \times \text{Dividend Yield}$$ - Adjust stock weights using the formula: $$\mathrm{w_{it}={\frac{w_{i0}\times\mathrm{\(1+R\)}}{\sum_{1}^{n}w_{i0}\times\mathrm{\(1+R\)}}}}$$ where \(w_{i0}\) is the initial weight, and \(R\) is the stock's return over the period[22] 4. **Forecast Dividend Impact on Contracts**: - Estimate ex-dividend dates based on historical patterns or announced schedules - Aggregate dividend impacts before the contract's settlement date to calculate the total dividend points and percentage impact on the futures contract[23][24][26] - **Model Evaluation**: The model provides a systematic approach to quantify dividend impacts, but its accuracy depends on assumptions about dividend payout ratios and ex-dividend dates[18][21][24] 2.

- The report introduces a multi-cycle timing strategy for interest rates, which is constructed using shape recognition algorithms to identify support and resistance lines in interest rate trends. The strategy combines signals from short, medium, and long cycles to form composite timing views. The switching frequency for these cycles is weekly, bi-weekly, and monthly, respectively[10][23][24] - The multi-cycle timing strategy is based on the principle that when at least two cycles show downward breakthroughs of support lines and the interest rate trend is not upward, the portfolio is fully allocated to long-duration bonds.
