1. Report Industry Investment Rating - No relevant content provided. 2. Core View of the Report - Today, all stock indices rebounded unilaterally. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets throughout the day was 2.4646 trillion yuan, an increase of 460.6 billion yuan compared to the previous day. Since early September, due to the significant increase in the prices of some individual stocks and a notable rise in the valuation, some investors' willingness to chase the market has weakened, and the profit - taking of profitable funds has led to a technical adjustment of the stock indices. However, the positive policy expectations and the continuous inflow of funds into the stock market still provide long - term support for the stock indices. The Minister of Finance pointed out that "in the next step, more efforts will be made to strengthen the domestic cycle, and more proactive and effective macro - policies will be implemented in a timely manner." Combined with the weak inflation data in August, it means that policies to boost the demand side will continue to be introduced, and the expectation of policy benefits is rising. On the other hand, incremental funds continue to flow into the stock market. The balance of margin trading has exceeded 2.3 trillion yuan and remains at a high level. The significant increase in non - bank deposits in July indicates that the trend of residents' maturing time deposits shifting to equity market allocation is gradually taking shape. The increasing expectation of the Fed's interest rate cut is conducive to driving the flow of the US dollar to emerging economies. Therefore, the trend of net inflow of incremental funds into the A - share market remains unchanged, which is expected to promote the repair of the stock market valuation. However, attention should still be paid to the intensity of profit - taking at the current position, and the subsequent market trend depends on the game between profit - taking and the fermentation of policy expectations. In general, the stock indices are expected to fluctuate widely in the short term [3]. - Currently, the implied volatility of options is within 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.

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.
