========= - The report tracks the dividend progress of constituent stocks in major indices such as the SSE 50, CSI 300, CSI 500, and CSI 1000, noting the number of companies at different stages of the dividend process[1][13] - The dividend yield of stocks with announced dividend plans is highest in the coal, banking, and steel industries[2][14] - The realized and remaining dividend yields for the SSE 50, CSI 300, CSI 500, and CSI 1000 indices as of December 24, 2025, are provided, with the SSE 50 having the highest realized yield at 2.70%[3][16] - The annualized premium and discount rates for the main contracts of IH, IF, IC, and IM futures as of December 24, 2025, are tracked, with IM having the highest annualized discount rate at -8.67%[4][12] - The methodology for calculating index dividend points is briefly reviewed, including the use of constituent stock weights, dividend amounts, and total market value[5][41] - The process for estimating constituent stock weights, including adjustments for stock price changes and the use of daily closing weights from the China Securities Index Company, is detailed[6][45][46] - The dynamic prediction method for net profit based on historical profit distribution is explained, including the classification of companies into stable and unstable profit distribution categories[7][47][50] - The prediction of dividend payout ratios using historical data and the linear extrapolation method for predicting ex-dividend dates are described[8][51][55] - The accuracy of the index dividend point estimation model is analyzed, showing higher accuracy for the SSE 50 and CSI 300 indices compared to the CSI 500 index[9][57][61] - The report includes charts showing the historical premium and discount rates of the main contracts for IH, IF, IC, and IM futures from 2020 to 2025[10][17][18][22] - The historical percentile positions of the basis for IH, IF, IC, and IM contracts are provided, indicating the relative premium levels of these contracts[11][27][29][35] =========

- The report introduces a quantitative model for estimating dividend points in stock indices, which is crucial for accurately assessing the basis and premium/discount levels of stock index futures contracts. The model incorporates key variables such as component stock weights, dividend amounts, total market capitalization, and index closing prices[43][48][12] - The model's construction process involves several steps: 1. Determining whether a company has announced dividend amounts and ex-dividend dates. If not, the ex-dividend date is estimated based on historical patterns[46] 2. Estimating dividend amounts for companies that have not disclosed them, which involves predicting net profits and dividend payout ratios. Net profit predictions are based on historical profit distributions, while payout ratios are estimated using historical averages[51][55] 3. Predicting ex-dividend dates using a linear extrapolation method based on the stability of historical intervals between announcement and ex-dividend dates[60] 4. Calculating the dividend points for the index using the formula: $$ \text{Dividend Points} = \sum_{n=1}^{N} \left( \frac{\text{Dividend Amount}_n}{\text{Market Cap}_n} \times \text{Weight}_n \times \text{Index Closing Price} \right) $$ Here, \(N\) represents the number of component stocks, and the calculation only includes stocks with ex-dividend dates between the current date and the futures contract expiration date[43][48][49] - The model's accuracy was evaluated by comparing predicted dividend points with actual dividend points for indices like the SSE 50, CSI 300, and CSI 500. The prediction error for the SSE 50 and CSI 300 indices was approximately 5 points, while the error for the CSI 500 index was around 10 points, indicating high accuracy for the first two indices and slightly larger deviations for the latter[65][66][70] - The model's application to stock index futures contracts showed strong predictive performance. For the SSE 50 and CSI 300 futures, the predicted dividend points closely matched the actual values, while the CSI 500 futures exhibited slightly larger deviations. This demonstrates the model's robustness, particularly for indices with larger market capitalization coverage[65][66][70]

Group 1 - The core viewpoint of the article highlights the dividend progress of constituent stocks in major indices as of December 10, 2025, indicating that many companies are not currently in the dividend distribution phase [1][3]. - In the Shanghai Stock Exchange 50 Index, there are no companies in the proposal, decision, or implementation stages, with three companies not distributing dividends [1][3]. - The Shanghai and Shenzhen 300 Index has one company in the proposal stage, while 20 companies are not distributing dividends [1][3]. - The dividend yield statistics show that the coal, banking, and steel industries rank the highest in terms of dividend yield among disclosed dividend proposals [1][4]. Group 2 - As of December 10, 2025, the realized dividend yields for major indices are as follows: Shanghai Stock Exchange 50 Index at 2.52% with a remaining yield of 0.42%, Shanghai and Shenzhen 300 Index at 2.04% with a remaining yield of 0.24%, and the China Securities 500 Index at 1.25% with a remaining yield of 0.03% [1][8]. - The China Securities 1000 Index has a realized dividend yield of 0.96% and a remaining yield of 0.01% [1][8]. - The article emphasizes the importance of tracking the annualized premium and discount of stock index futures, which reflects institutional investors' market sentiment and risk preferences [2][3]. Group 3 - The article provides a detailed methodology for estimating dividend points in stock indices, which is crucial for accurately assessing the premium and discount of stock index futures [30][32]. - It discusses the significance of considering dividend distributions in the calculation of index futures, as they can lead to a natural decline in index points [30][32]. - The methodology includes estimating individual stock weights, dividend amounts, and the timing of dividend distributions based on historical data [30][32][39].

- The report introduces a method for calculating the dividend points of stock indices, which is crucial for accurately estimating the premium or discount of stock index futures contracts. The formula for dividend points is as follows: $ \text{Dividend Points} = \sum_{n=1}^{N} \left( \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} \right) $ This calculation considers only the component stocks with ex-dividend dates between the current date (t) and the futures contract expiration date (T) [41] - The weight of component stocks is dynamically adjusted to reflect daily changes. The formula for calculating the weight is: $ W_{n,t} = \frac{w_{n0} \times (1 + r_{n})}{\sum_{i=1}^{N} w_{i0} \times (1 + r_{i})} $ Here, $w_{n0}$ is the weight of stock n on the last disclosed date, and $r_{n}$ is the non-adjusted return of stock n from the last disclosed date to the current date [45] - The estimation of dividend amounts involves predicting net profits and dividend payout ratios. The dividend amount is calculated as: $ \text{Dividend Amount} = \text{Net Profit} \times \text{Dividend Payout Ratio} $ For companies with stable profit distributions, historical patterns are used for prediction. For others, the previous year's profit is used as the estimate [47][50] - The dividend payout ratio is estimated using historical averages. If a company paid dividends in the previous year, the last year's ratio is used. If not, the average of the past three years is applied. If no historical data exists, the company is assumed not to pay dividends [51][53] - The ex-dividend date is predicted using a linear extrapolation method based on the stability of historical intervals between announcement dates and ex-dividend dates. If no reliable historical data is available, default dates are assigned based on typical dividend schedules [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 predicting dividend points of stock index futures contracts [57][61]

- The report discusses the methodology for calculating dividend points in stock indices, which is crucial for accurately estimating the premium or discount in stock index futures contracts. The calculation involves the following formula: **Dividend Points = (Sum of Dividend Amounts / Total Market Value) × Component Stock Weight × Index Closing Price** This formula considers only the component stocks with ex-dividend dates between the current date and the futures contract expiration date [42][45] - The weight of component stocks is dynamically adjusted to reflect daily changes in stock prices. The formula for calculating the weight is: **$W_{n,t} = \frac{w_{i0} \times (1 + r_{n})}{\sum_{i=1}^{N} w_{i0} \times (1 + r_{n})}$** Here, $w_{i0}$ is the weight of stock $n$ on the last disclosed date, and $r_{n}$ is the non-adjusted return of stock $n$ from the last disclosed date to the current date [46] - The estimation of dividend amounts is based on the product of net profit and dividend payout ratio. If the company has not disclosed its dividend amount, the net profit is predicted using historical profit distribution patterns, and the dividend payout ratio is estimated using historical averages. The formula is: **Dividend Amount = Net Profit × Dividend Payout Ratio** For companies with stable profit distribution, historical patterns are used, while for others, the previous year's profit is used as a proxy [48][51][52] - The ex-dividend date is predicted using a linear extrapolation method based on the stability of historical intervals between announcement dates and ex-dividend dates. If no historical data is available, default dates are assigned based on typical market behavior [52][57] - The accuracy of the dividend point estimation model is evaluated by comparing predicted dividend points with actual dividend points. For indices like the SSE 50 and CSI 300, the model achieves high accuracy with errors around 5 points, while for the CSI 500, the error is slightly larger, around 10 points [58][62]

- The report discusses the dividend progress of constituent stocks in various indices, including the SSE 50, CSI 300, CSI 500, and CSI 1000 indices, highlighting the number of companies in different stages of the dividend process[1][15] - The dividend yield comparison across different industries shows that the coal, banking, and steel industries have the highest dividend yields[2][16] - The realized and remaining dividend yields for the SSE 50, CSI 300, CSI 500, and CSI 1000 indices are provided, with specific values for each index as of November 26, 2025[3][3][18] - The report tracks the basis and annualized discount rates of the main contracts for IH, IF, IC, and IM futures, reflecting the market sentiment and risk preferences of institutional investors[4][4][12] - The methodology for calculating the dividend points of stock indices is explained, including the estimation of constituent stock weights, dividend amounts, total market value, and index closing prices[5][41][44] - The accuracy of the dividend point estimation model is evaluated, showing that the model performs well for the SSE 50 and CSI 300 indices, with slightly larger errors for the CSI 500 index[6][57][61] - The report includes detailed steps for predicting the net profit and dividend payout ratio of constituent stocks, using historical data and dynamic forecasting methods[7][47][50] - The prediction of ex-dividend dates is based on the stability of historical interval days, with a linear extrapolation method used for estimation[8][51][56] - The report provides a comprehensive analysis of the dividend point estimation process, including the use of daily closing weight data from the China Securities Index Company to ensure accuracy[9][46][48]

- The report focuses on the methodology for calculating dividend points in stock indices, which is critical for accurately estimating the basis and premium/discount levels of stock index futures contracts[12][41][42] - The calculation of dividend points involves the following formula: $$ \text{Dividend Points} = \sum_{n=1}^{N} \left( \frac{\text{Dividend Amount of Component Stock}}{\text{Total Market Value of Component Stock}} \times \text{Weight of Component Stock} \times \text{Index Closing Price} \right) $$ Here, \(N\) represents the number of component stocks, and the calculation considers only those stocks with ex-dividend dates between the current date (\(t\)) and the futures contract expiration date (\(T\))[41][42][46] - The methodology includes several key steps: 1. **Component Stock Weight Adjustment**: The weights of component stocks are adjusted dynamically based on their price changes since the last disclosed weight data. The formula used is: $$ W_{n,t} = \frac{w_{n0} \times (1 + r_n)}{\sum_{i=1}^{N} w_{i0} \times (1 + r_i)} $$ Here, \(w_{n0}\) is the weight of stock \(n\) at the last disclosed date, and \(r_n\) is its price change since then[47][48] 2. **Net Profit Estimation**: For stocks without disclosed dividend amounts, net profit is estimated using historical profit distributions. Stable companies use historical patterns, while others rely on the previous year's profit[49][52] 3. **Dividend Payout Ratio Estimation**: Historical payout ratios are used to estimate the current year's ratio. Adjustments are made for companies with no prior dividends or extreme payout ratios[53][55] 4. **Ex-Dividend Date Prediction**: Ex-dividend dates are predicted using historical intervals or default dates if no reliable historical data is available[53][58] - The accuracy of the dividend point estimation model is validated by comparing predicted and actual dividend points for indices like the SSE 50, CSI 300, and CSI 500. The model shows high accuracy, with errors generally within 5 points for SSE 50 and CSI 300, and within 10 points for CSI 500[59][63] - The report also tracks the premium/discount levels of major stock index futures contracts (IH, IF, IC, IM) and their historical percentile rankings. For example, as of November 19, 2025, the IH contract is at the 28th percentile, IF at the 41st, IC at the 69th, and IM at the 83rd percentile[28][32][34]
