1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - On September 4, 2025, all stock indices showed weak oscillations and significant declines. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2581.9 billion yuan, an increase of 186.2 billion yuan from the previous day, and nearly 3000 stocks declined. Due to the significant gains of some stocks, the profit - taking demand of profit - making funds increased, leading to a short - term technical adjustment in the stock indices, with the CSI 500 and CSI 1000 indices being more affected. However, in the medium - to - long term, the positive policy expectations and loose capital situation strongly support the stock indices, and the logic of their upward movement remains strong. Recently, the joint working group of the Ministry of Finance and the People's Bank of China held its second group leader meeting, indicating a clear expectation of policy support for the economy. The liquidity is relatively loose, and in the context of the "asset shortage", the attractiveness of equity assets is strong, with incremental funds continuously flowing in, which will drive the repair of stock valuations. In general, due to the increased profit - taking demand of profit - making funds, the stock indices are expected to fluctuate widely in the short term. Currently, the implied volatility of options continues to rise. Considering the medium - to - long - term upward trend of the stock indices, one can continue to hold bull spreads or ratio spreads for a mild bullish view [3]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Report's Core View - On September 3, 2025, all stock indices fluctuated and declined. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.3957 trillion yuan, a decrease of 516.7 billion yuan from the previous day. Due to the significant increase in some stocks, the profit - taking demand of profitable funds has risen, and the recent trading volume of the stock market has shrunk, indicating a certain divergence in market expectations, and the stock indices have entered a short - term technical adjustment. In the long - term, the expectation of policy benefits and the loose capital situation strongly support the stock indices, and the logic of the long - term upward movement of the stock indices remains strong. Anti - involution policies and consumption - promotion policies optimize the supply - demand structure from both the supply and demand sides, promote a moderate increase in the price index, and repair corporate profits. In terms of capital, the margin trading balance has risen rapidly, non - bank deposits have soared, and long - term funds have continued to enter the market. The continuous inflow of incremental funds in the stock market promotes the repair of stock valuations. In general, in the short term, the marginal effect of policy benefit expectations has weakened, and the profit - taking demand of profitable funds has increased. The stock indices are expected to fluctuate widely in the short term. Currently, the implied volatility of options continues to rise. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or ratio spreads for a mild bullish view [3]. 3.

Industry Investment Rating - No investment rating information provided in the report Core Viewpoints - Today, all stock indices fluctuated within a narrow range. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1736.3 billion yuan, a decrease of 116.2 billion yuan from the previous day. The economic indicators in the first half of the year showed strong resilience, and the expectation of short - term policy intensification has weakened, but the expectation of policy support still exists. Policy support and the expectation of anti - involution policy benefits have promoted the recovery of the stock market's risk appetite, combined with the suspension of overseas uncertainty risks, jointly driving the recovery of the stock market's risk appetite. Considering that some stocks have achieved significant gains, there is a need for technical consolidation in the market outlook. With the approaching deadline of the Sino - US tariff suspension period, there is a possibility of consolidation and accumulation of momentum for stock indices in the short term. However, in the long term, the upward trend of stock indices remains unchanged. Currently, the risk appetite of the stock market is relatively positive, and it is expected that stock indices will maintain a volatile and slightly stronger trend in the short term.

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Viewpoints - The stock market has a relatively strong risk appetite, and stock indices are oscillating upwards. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets is 1518.2 billion yuan, a decrease of 101.7 billion yuan from the previous day. The trading volume remains above 1.5 trillion yuan, indicating a high - level risk appetite among stock market investors [3]. - The economy showed strong resilience in the second quarter, reducing the short - term expectation of policy intensification. The subsequent incremental positive factors need to wait until October, so the positive policy drive has weakened recently [3]. - Since late June, some stocks have achieved significant gains, and some profit - taking funds have a need to lock in profits. Therefore, the stock indices have a short - term need for technical consolidation. However, external risk factors are easing, domestic economic data shows resilience, the stock market risk appetite is at a high level, and there are few negative factors. In the short term, the stock indices are more likely to rise than fall. Overall, the stock indices are upward - trending in the long - term and will mainly oscillate within a range in the short - term [3]. - The implied volatility of options is currently in the normal range. Considering the long - term upward trend of stock indices, investors can continue to hold bull spreads or ratio spreads for a mild bullish view [3]. 3.

1. Report Industry Investment Rating - No relevant content provided 2. Core Views of the Report - Today, all stock indices fluctuated and consolidated. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1619.9 billion yuan, a decrease of 342 billion yuan from the previous day. Due to the significant gains of some stocks since late June, some profit - taking funds have a need to lock in profits, so the stock indices have a short - term need for technical consolidation. The recent decline in the trading volume of the stock market indicates a decline in investors' risk appetite. Since incremental policy benefits may need to wait until the Fourth Plenary Session of the 20th CPC Central Committee in October, the driving force of policy benefits has weakened marginally in the short term. In general, the stock indices are expected to fluctuate within a range in the short term. Currently, the implied volatility of options has rebounded. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or ratio spreads for a mild bullish view [3] 3.
