1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - On September 24, 2025, all stock indices rose, with CSI 500 and CSI 1000 leading the gains. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 234.71 billion yuan, a decrease of 17.13 billion yuan from the previous day. The rebound was accompanied by a contraction in trading volume and a reduction in the positions of stock index futures, indicating that investors still have differences in their views on the future market [3]. - The main trading logic of the stock market currently comes from policy expectations and capital flows. In the future, it is necessary to focus on the game between the profit - taking rhythm of funds and the fermentation of policy expectations. As the valuation has significantly increased, especially when the index rebounds to near the previous high, the demand for profit - taking of profitable funds has increased. On the other hand, the expectation of policy benefits and the long - term net inflow trend of funds constitute the medium - and long - term driving force for the upward movement of stock indices. The fermentation of policy benefits is expected to await the convening of the important meeting in October. The fact that the margin trading balance has exceeded 2.4 trillion yuan and the year - on - year significant increase in new non - bank deposits in July and August indicate that the signs of residents' wealth allocation to the equity market have begun to appear [3]. - In the short term, the stock index is expected to fluctuate widely because the index is close to the previous high and the long holiday is approaching. Currently, the implied volatility of options has declined. Considering the medium - and long - term upward trend of the stock index, investors can continue to hold bull spreads or ratio spreads [3]. 3.

The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2518.6 billion yuan, an increase of 376 billion yuan from the previous day. There are certain differences in market sentiment currently. It is necessary to focus on the game between the profit - taking rhythm of funds and the fermentation of policy expectations.

The fermentation of policy benefit expectations awaits the convening of the important meeting in October. The increase in incremental funds can be seen from the fact that the margin trading balance has exceeded 2.4 trillion yuan and the year - on - year increase in new non - bank deposits in July and August was significant.

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - On September 18, 2025, the stock indexes fluctuated and declined throughout the day, with the Shanghai, Shenzhen, and Beijing stock markets having a total turnover of 3166.6 billion yuan, a significant increase of 763.7 billion yuan from the previous day. The decline was mainly due to large stock price increases and significant valuation improvements, causing investors to lose confidence in chasing prices and increasing their willingness to take profits. [3] - In the medium to long term, stock indexes are strongly supported by favorable macro - policies and net inflows of funds. Given the weak credit and inflation data in August and the slowdown in consumption growth, there is a high expectation of policies to stabilize demand, with the key window period for policy introduction expected to be in October. The significant increase in non - bank deposits in July and August and the high - level operation of margin trading balances indicate continuous inflows of incremental funds into the stock market. [3] - However, due to the significant increase in the valuation of some stocks, there is still a willingness among profitable funds to take profits, leading to short - term technical adjustment pressure on stock indexes. The subsequent focus should be on the game between the rhythm of profit - taking and the fermentation of policy expectations. In general, stock indexes are expected to experience wide - range fluctuations in the short term. [3] - Currently, the implied volatility of options has increased. Considering the long - term upward trend of stock indexes, investors can continue to hold bull spreads or ratio spreads. [3] 3.

For instance, the trading volume PCR of the Shanghai Stock Exchange 50ETF options was 78.41 (previous day: 87.34), and the open - interest PCR was 73.26 (previous day: 76.66).

There is a strong expectation for the introduction of policies to stabilize demand in the future, and the critical window period for policy introduction is expected to be in October [4]. - In terms of capital, incremental funds have been continuously flowing into the stock market. The non - bank deposits increased significantly in July and August, and the margin trading balance remained at a high level, indicating that the stock market has continuously attracted incremental funds. However, due to the significant increase in the valuations of some stocks in the early stage, there is still a willingness among profit - taking funds to take profits, which also leads to short - term technical adjustment pressure on the stock indices. In the future, focus on the game between the profit - taking rhythm of funds and the fermentation of policy expectations [4]. - In general, the stock indices are expected to experience wide - range fluctuations in the short term. Currently, the implied volatility of options is in the normal range. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or ratio spreads [4]. 3.
