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.

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.
