- The report predicts adjustments to the sample stocks of the CSI 300, CSI 500, and CSI Dividend indices for December 2025 based on their respective index compilation and periodic adjustment rules[13][14][21] - **CSI 300 Index**: The CSI 300 Index is composed of 300 securities with large scale, good liquidity, and high representativeness from the Shanghai and Shenzhen markets. The selection process involves determining the sample space and then selecting the top 300 securities based on daily average trading volume and market capitalization over the past year. Adjustments are capped at 10% of the total sample size, with buffer zone rules applied to prioritize retention of existing samples and inclusion of new ones ranked within specific thresholds[14][15][16] - **CSI 500 Index**: The CSI 500 Index excludes the CSI 300 samples and the top 300 securities by market capitalization. The remaining securities are ranked by daily average trading volume and market capitalization, with the top 500 selected. Adjustments are also limited to 10% of the total sample size, with buffer zone rules ensuring the retention of old samples and prioritization of new ones ranked within specific thresholds[21][23] - **CSI Dividend Index**: This index selects 100 securities with high cash dividend yields, stable dividends, and sufficient liquidity. The selection process involves ranking securities by their average cash dividend yield over the past three years and applying liquidity and dividend payout ratio requirements. Adjustments are limited to 20% of the total sample size, with buffer zone rules applied to retain existing samples meeting specific criteria[25][26][28] - Predicted adjustments include the addition of 11 stocks to the CSI 300 Index, 50 stocks to the CSI 500 Index, and 7 stocks to the CSI Dividend Index.

Core Viewpoint - The adjustment of the Sci-Tech Innovation 50 Index will likely lead to a reduction in the weight of the stock "Cambricon" due to its current weight exceeding the regulatory limit, which may result in related funds needing to sell off shares to comply with the new weight requirements [1][2]. Group 1: Index Adjustment Details - The weight of a single sample in the Sci-Tech Innovation 50 Index cannot exceed 10%, and the combined weight of the top five samples must not exceed 40% [2]. - As of September 2, Cambricon's weight in the index reached 15.42%, necessitating a reduction to comply with the index rules [2]. - The adjustment will take effect on September 15, with an estimated sell-off of around 10 billion yuan (approximately 100 million) in Cambricon shares required to meet the new weight limit [1][2]. Group 2: Market Reactions and Investor Guidance - Industry insiders suggest that investors should not overly worry about short-term fluctuations, as the core value of index funds lies in tracking long-term returns rather than reacting to short-term adjustments [3][4]. - The adjustment may lead to a rebalancing of funds within the index, as other stocks with lower weights may receive increased investment [4]. - Investors are encouraged to focus on the post-adjustment industry distribution and performance resilience of the index rather than short-term market changes [5].
