For companies with stable profit distribution, historical profit distribution patterns are used for prediction; for companies with unstable profit distribution, the previous year's profit is used as the forecast value[49][52] - The dividend payout ratio is predicted using historical data averages. If a company has paid dividends in the past, the historical payout ratio is used as the estimate for the current year[53][55] - The ex-dividend date is predicted based on the stability of the interval days between the announcement of the dividend plan and the ex-dividend date in the past three years. If the interval days are stable, the average interval days are used for linear extrapolation; otherwise, historical ex-dividend dates are used for estimation[57][58] - The accuracy of the dividend point estimation model is analyzed by comparing the predicted dividend points with the actual dividend points at different time points. The model shows high accuracy for the Shanghai Stock Exchange 50 Index and the CSI 300 Index, with errors within 5 points, while the prediction error for the CSI 500 Index is slightly larger, but still within 10 points[59][63] - The report tracks the premium and discount levels of stock index futures contracts, including the daily basis, the trend of the main contract's premium and discount, the term structure of different contracts' basis, and the current basis level in historical percentiles[12][13][28] - The main contracts of IH, IF, IC, and IM show varying levels of annualized discount rates, with IH at 0.76%, IF at 9.98%, IC at 39.34%, and IM at 43.79%[4][13] - The historical percentile levels of the main contracts' basis indicate that the IH main contract is around the 36th percentile, the IF main contract is at the 23rd percentile, the IC main contract is at the 8th percentile, and the IM main contract is at the 6th percentile[28][29][38] Model Testing Results - IH main contract, annualized discount rate: 0.76%[4] - IF main contract, annualized discount rate: 9.98%[4] - IC main contract, annualized discount rate: 39.34%[4] - IM main contract, annualized discount rate: 43.79%[4]

- The report introduces a quantitative model for estimating dividend points in stock indices, which is crucial for accurately assessing the premium or discount in stock index futures contracts. The model incorporates factors such as component stock weights, dividend amounts, total market capitalization, and index closing prices[38][44][46] - The model calculates the dividend points for a stock index during the period from the current date (t) to the futures contract expiration date (T) using the formula: $$ \text{Dividend Points} = \sum_{n=1}^{N} \left( \frac{\text{Dividend Amount of Stock n}}{\text{Total Market Cap of Stock n}} \times \text{Weight of Stock n} \times \text{Index Closing Price} \right) $$ This formula ensures that only stocks with ex-dividend dates between t and T are included[38][44] - Component stock weights are dynamically adjusted using the formula: $$ W_{n,t} = \frac{w_{n0} \times (1 + r_{n})}{\sum_{i=1}^{N} w_{i0} \times (1 + r_{i})} $$ Here, \( w_{n0} \) represents the weight of stock \( n \) at the last disclosed date, and \( r_{n} \) is the non-adjusted return of stock \( n \) between the last disclosed date and the current date[45] - The model estimates net profit for stocks without disclosed data by categorizing companies into stable and unstable profit distribution groups. Stable companies are predicted based on historical patterns, while unstable ones use the previous year's profit as a proxy[47][50] - Dividend payout ratios are estimated using historical averages. If a company paid dividends in the previous year, that ratio is used; otherwise, a three-year average is applied. Companies with no dividend history are assumed not to pay dividends[51][53] - Ex-dividend dates are predicted using a linear extrapolation method based on historical intervals between announcement and ex-dividend dates. Default dates are applied if historical data is insufficient or inconsistent[51][56] - The model's accuracy was validated by comparing predicted dividend points with actual values for the Shanghai 50, CSI 300, and CSI 500 indices in 2023 and 2024. The Shanghai 50 and CSI 300 predictions showed errors within 5 points, while the CSI 500 had slightly larger errors, around 10 points[57][61][66]

- The report introduces a dividend point estimation model for stock indices, which is crucial for accurately assessing the premium or 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[38][43][39] - Component stock weights are dynamically adjusted using daily closing weight data provided by the China Securities Index Company to ensure accuracy. The formula for weight adjustment is: $$W_{n,t}={\frac{w_{i0}\times(1+r_{n})}{\sum_{i=1}^{N}w_{i0}\times(1+r_{n})}}$$ where \(w_{i0}\) represents the weight at the last disclosed date, and \(r_{n}\) is the non-reinvested return of the stock[44][45] - Dividend amounts are estimated using historical net profit distributions and dividend payout ratios. If a company has disclosed its annual dividend, the disclosed value is used; otherwise, the dividend is calculated as: Dividend Amount = Net Profit × Dividend Payout Ratio Net profit is predicted based on historical quarterly profit stability, while the dividend payout ratio is derived from historical averages[46][49][50] - Ex-dividend dates are forecasted using a linear extrapolation method based on historical intervals between dividend announcement dates and ex-dividend dates. If historical data is unavailable or unreliable, default dates are applied based on typical dividend timing patterns[50][55][54] - The model demonstrates high accuracy in predicting dividend points for major indices such as the SSE 50 and CSI 300, with annual prediction errors generally within 5 points. Predictions for the CSI 500 index show slightly larger deviations, typically around 10 points[56][60][64] - Backtesting results for stock index futures contracts reveal varying levels of annualized discount rates as of August 6, 2025: - IH futures: -0.93% - IF futures: -3.52% - IC futures: -18.10% - IM futures: -15.40%[4][13][12]

- The report introduces the dividend point estimation method for stock indices, emphasizing its importance in accurately assessing the premium or discount levels of stock index futures contracts. The calculation involves the weighted sum of dividend amounts divided by total market capitalization, adjusted by index closing prices[39][40][42] - The methodology for estimating dividend points includes key steps such as obtaining constituent stock weights, estimating dividend amounts, predicting net profits using historical distributions, and forecasting dividend payout ratios based on historical averages. Additionally, the ex-dividend date is predicted using linear extrapolation of historical intervals[42][44][47] - The formula for constituent stock weight adjustment is provided as: $$W_{n,t}={\frac{w_{i0}\times(1+r_{n})}{\sum_{i=1}^{N}w_{i0}\times(1+r_{n})}}$$ where \(w_{i0}\) represents the weight at the last disclosed date, and \(r_{n}\) denotes the non-reinvested return of stock \(n\)[45][46] - The report evaluates the accuracy of the dividend point estimation model, showing that for indices like SSE 50 and CSI 300, the annual prediction error is within 5 points, while for CSI 500, the error is slightly larger at around 10 points[57][61] - Historical data analysis reveals that the prediction model performs well for stock index futures contracts, with minimal deviation between forecasted and actual dividend points for SSE 50 and CSI 300 futures. CSI 500 futures exhibit slightly higher deviation[61][65][66]
