- The report introduces the methodology for calculating index dividend points, which is crucial for accurately estimating the premium or discount of stock index futures contracts. The calculation considers the dividend impact of index constituent stocks, including their dividend amount, market capitalization, weight, and index closing price[39][40][44] - The weight of index constituent stocks is refined from monthly data provided by mainstream data providers to daily data disclosed by the China Securities Index Company. This ensures higher accuracy in capturing the daily weight changes of individual stocks[45][46] - The estimation of dividend amounts involves predicting net profits and dividend payout ratios. Net profit prediction is based on historical profit distribution dynamics, categorizing companies into stable and unstable profit distribution groups. Stable companies use historical patterns for prediction, while unstable ones rely on the previous year's profit as a forecast[47][50] - Dividend payout ratio prediction uses historical averages. If a company paid dividends last year, the previous year's payout ratio is used. If not, the average of the past three years is applied. Companies with no dividend history are assumed not to pay dividends[51][53] - The prediction of ex-dividend dates employs a linear extrapolation method based on the stability of historical interval days between dividend announcement and ex-dividend dates. Default dates are set for companies with insufficient historical data or no dividend history[55][56] - The accuracy of the dividend point estimation model is validated by comparing predicted dividend points with actual dividend points for major indices like the SSE 50, CSI 300, and CSI 500. The model shows high accuracy for SSE 50 and CSI 300, with errors around 5 points, while errors for CSI 500 are slightly larger, around 10 points[57][61]

Group 1 - As of October 29, 2025, no companies in the Shanghai 50, CSI 300, CSI 500, and CSI 1000 indices are in the proposal, decision, or implementation stages for dividends, with a total of 3, 20, 46, and 138 companies respectively not distributing dividends [1][3] - The coal, banking, and steel industries have the highest median dividend yields among the disclosed dividend proposals [4] - The realized dividend yields as of October 29, 2025, are 2.45% for the Shanghai 50, 1.96% for the CSI 300, 1.20% for the CSI 500, and 0.92% for the CSI 1000, with remaining yields of 0.10%, 0.11%, 0.05%, and 0.04% respectively [7][6] Group 2 - The annualized premium and discount for the main futures contracts as of October 29, 2025, are 1.93% for IH, -0.96% for IF, -8.26% for IC, and -10.23% for IM [1] - The tracking of the premium and discount levels of stock index futures will consider the impact of dividend distributions on index points, which is crucial for accurately estimating the premium and discount of futures contracts [2][23] Group 3 - The dividend progress for the indices is expected to be concentrated in November and December, as shown in the forecasts for the Shanghai 50, CSI 300, CSI 500, and CSI 1000 indices [16] - The methodology for estimating dividend points involves calculating the dividend amounts based on the weights of constituent stocks, their market values, and the index closing prices [25][26]

- The report discusses the methodology for calculating index dividend points, which is crucial for accurately estimating the premium or discount of stock index futures contracts. The formula for dividend points is: $ Dividend\ Points = \sum_{n=1}^{N} \frac{Dividend\ Amount}{Total\ Market\ Value} \times Component\ Weight \times Index\ Closing\ Price $ This calculation considers the dividend amount, total market value, component weight, and index closing price, ensuring precision in estimating the impact of dividends on index points[39][44][57] - Component weights are refined from rough estimates to precise daily data. The formula for adjusting weights is: $ W_{n,t} = \frac{w_{n0} \times (1 + r_{n})}{\sum_{i=1}^{N} w_{i0} \times (1 + r_{i})} $ Here, $ w_{n0} $ represents the weight of component $ n $ at the last disclosed date, and $ r_{n} $ is the non-adjusted return of the component stock. This ensures daily accuracy in weight calculations[45][46] - Net profit prediction is based on historical profit distribution dynamics. Companies are categorized into stable and unstable profit distribution groups. Stable companies use historical patterns for prediction, while unstable ones rely on the previous year's profit as the forecast value[47][50] - Dividend payout ratio prediction uses historical averages. For companies with stable operations, the previous year's payout ratio is used. If no dividends were issued in the past, the average of the last three years is applied. If the payout ratio exceeds 100%, it is capped[51][53] - Ex-dividend date prediction employs a linear extrapolation method based on historical intervals. If a company has not disclosed its ex-dividend date, historical data is used, or default dates are applied based on the calendar year[51][56] - The accuracy of the dividend point estimation model is evaluated. For the Shanghai 50 and CSI 300 indices, the annual prediction error is approximately 5 points, while for the CSI 500 index, the error is around 10 points. The model demonstrates high accuracy for stock index futures contracts, particularly for Shanghai 50 and CSI 300 futures[57][61][66]

- The report introduces the dividend point estimation method for stock indices, emphasizing its importance in accurately calculating the premium or discount of stock index futures contracts, which track price indices rather than total return indices[39][12][44] - The dividend point estimation formula is presented as follows: $$Dividend\ Points = \sum_{n=1}^{N} \frac{Dividend\ Amount_{n}}{Total\ Market\ Value_{n}} \times Weight_{n} \times Index\ Closing\ Price$$ Here, \(n\) represents the index constituent stock, \(Weight_{n}\) is the stock's weight in the index, and \(Dividend\ Amount_{n}\) is the dividend amount of the stock[39][44][40] - The estimation process involves several steps: 1. Determine whether the company has disclosed dividend amounts and ex-dividend dates. If not, estimate these values[42] 2. Estimate dividend amounts using the formula \(Dividend\ Amount = Net\ Profit \times Dividend\ Payout\ Ratio\), where net profit is dynamically predicted based on historical profit distributions[47][50] 3. Predict dividend payout ratios using historical averages, applying truncation if the ratio exceeds 100%[51][53] 4. Forecast ex-dividend dates using historical intervals and linear extrapolation methods[56][55][53] - The report highlights the accuracy of the dividend point estimation model, noting that for indices like the SSE 50 and CSI 300, the prediction error is within 5 points, while for CSI 500, the error is around 10 points[57][61][62] - The backtesting results for stock index futures contracts show varying annualized premium or discount levels: - IH main contract: annualized premium of 0.55%[4][13] - IF main contract: annualized discount of 2.85%[4][13] - IC main contract: annualized discount of 10.08%[4][13] - IM main contract: annualized discount of 12.15%[4][13] - The historical percentile levels of the main contracts are also analyzed: - IH contract is at the 49th percentile[27][29] - IF contract is at the 24th percentile[27][29] - IC contract is at the 12th percentile[27][32] - IM contract is at the 8th percentile[27][32] - The report concludes that the deeper the market capitalization coverage of the index, the greater the discount observed in the futures contracts[24][27][12]

- The report introduces the dividend point estimation method for stock indices, emphasizing its importance in accurately calculating the premium or discount levels of stock index futures contracts, which track price indices rather than total return indices[39][12][44] - The dividend point estimation formula is provided as follows: $$ \text{Dividend Points} = \sum_{n=1}^{N} \frac{\text{Dividend Amount of Component Stock}}{\text{Total Market Value of Component Stock}} \times \text{Weight of Component Stock} \times \text{Index Closing Price} $$ This formula requires the dividend amount, total market value, weight of component stocks, and index closing price, with the condition that the ex-dividend date of the stock must fall between the current date and the futures contract expiration date[39][44][45] - The report details the process of estimating component stock weights, transitioning from imprecise monthly data to precise daily data provided by the China Securities Index Company, ensuring accuracy in daily weight calculations[45][46] - The estimation of dividend amounts involves predicting net profits and dividend payout ratios. Net profit prediction uses historical profit distribution dynamics, categorizing companies into stable and unstable profit distribution groups, and applying respective methods for estimation[47][50][52] - Dividend payout ratio prediction employs historical averages, with adjustments based on past dividend behavior. Companies with no dividend history are assumed not to pay dividends, and ratios exceeding 100% are capped[51][53][56] - Ex-dividend date prediction uses historical intervals for linear extrapolation, considering factors like past dividend dates, shareholder meeting schedules, and default dates for companies with no dividend history[51][55][56] - The accuracy of the dividend point estimation model is validated through comparisons of predicted and actual dividend points for indices like the SSE 50, CSI 300, and CSI 500. The model demonstrates high accuracy, with errors generally within 5 points for SSE 50 and CSI 300, and slightly larger errors for CSI 500, around 10 points[57][61][66]

Quantitative Models and Construction Methods - **Model Name**: Index Dividend Points Estimation Model **Model Construction Idea**: This model aims to estimate the dividend points of stock indices to account for the impact of constituent stock dividends on index futures' premium/discount levels. It is essential for accurately calculating the basis and premium/discount levels of index futures contracts[11][44][47] **Model Construction Process**: 1. **Formula**: Dividend Points = $ \sum_{n=1}^{N} \frac{\text{Dividend Amount of Constituent Stock}}{\text{Total Market Value of Constituent Stock}} \times \text{Constituent Stock Weight} \times \text{Index Closing Price} $ - \( N \): Number of constituent stocks - Dividend amounts are considered only if the ex-dividend date falls between the current date (\( t \)) and the contract expiration date (\( T \))[44] 2. **Steps**: - Obtain constituent stock weights and index closing prices - For stocks with announced dividend amounts and ex-dividend dates, use the provided data - For stocks without announced data, estimate dividend amounts based on historical net profit and payout ratios, and predict ex-dividend dates using historical patterns[45][47] **Model Evaluation**: The model demonstrates high accuracy for indices like the SSE 50 and CSI 300, with prediction errors around 5 points. However, the accuracy for the CSI 500 index is slightly lower, with errors around 10 points[64] - **Model Name**: Dynamic Prediction of Net Profit **Model Construction Idea**: This model predicts annual net profit for constituent stocks based on historical profit distribution patterns, enabling the estimation of dividend amounts for stocks without disclosed data[50][53] **Model Construction Process**: 1. Classify companies into two categories: stable and unstable profit distribution 2. For stable companies, predict based on historical profit distribution patterns 3. For unstable companies, use the previous year's corresponding period profit as the prediction value[53][55] **Model Evaluation**: The model effectively captures profit trends for stable companies but may face challenges with companies exhibiting irregular profit patterns[53] - **Model Name**: Historical Dividend Payout Ratio Estimation **Model Construction Idea**: This model estimates the dividend payout ratio for constituent stocks based on historical averages, assuming stability in payout ratios for companies with consistent operations[54] **Model Construction Process**: 1. If the company paid dividends last year, use the previous year's payout ratio 2. If no dividends were paid last year, use the average payout ratio of the past three years 3. If the company has never paid dividends, assume no dividends for the current year 4. Cap the payout ratio at 100% to avoid unrealistic estimates[56] **Model Evaluation**: The model is suitable for companies with stable operations but may not be accurate for firms with volatile financial policies[54] - **Model Name**: Ex-Dividend Date Prediction Model **Model Construction Idea**: This model predicts the ex-dividend dates of constituent stocks based on historical intervals between announcement and ex-dividend dates[54][59] **Model Construction Process**: 1.
