Main Variety Price Market Driving Logic - Financial Futures Stock Index Sector - For IF, IH, IC, and IM, the intraday view is shock - biased upward, the medium - term view is upward, and the reference view is wide - range shock. The core logic is that yesterday, each stock index showed shock and differentiation. The Shanghai Composite 50 and CSI 300 closed up in shock, while the CSI 500 and CSI 1000 closed down in shock. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 194.87 billion yuan, a decrease of 14.17 billion yuan from the previous day. The newly released September financial data shows that the financing demand of the household sector is still weak, and the problem of insufficient effective domestic demand still exists. Coupled with the external tariff factor disturbance, the expectation of policy - side stabilizing the macro - fundamentals is strong, which forms the medium - and long - term support for the stock index. However, in the short term, there are still external uncertainty risks before November, and the stock valuation has increased significantly, so investors' willingness to take profits has risen, and there is short - term technical adjustment pressure [5].

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Today, the stock indices showed mixed trends. The SSE 50 and CSI 300 closed up, while the CSI 500 and CSI 1000 closed down. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1948.7 billion yuan, a decrease of 141.7 billion yuan from the previous day. The latest financial data for September indicates that the financing demand of the household sector remains weak, and the problem of insufficient effective domestic demand persists. Coupled with the ongoing impact of external tariff factors, there are strong expectations for policy measures to stabilize the macro - fundamentals in the future, which will provide long - term support for the stock indices. However, in the short term, there are still uncertainties and risks before November, and the significant increase in stock valuations has led to an increase in investors' willingness to take profits, resulting in short - term technical adjustment pressure. Overall, the subsequent market trend depends on the interaction between profit - taking sentiment and policy - driven positive expectations, and the stock indices are expected to remain volatile in the short term. Currently, the implied volatility of options remains relatively stable. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or covered calls [4]. 3.

Core View of the Report - The stock index is expected to maintain wide - range fluctuations in the short term due to the game between profit - taking sentiment and policy support. In the medium term, it is expected to rise as the inflow trend of funds into A - shares remains unchanged and policy support is strong [1][5]. 3. Summary by Related Catalogs Variety View Reference - Financial Futures Stock Index Sector - For IH2512, the short - term view is "oscillation", the medium - term view is "rise", the intraday view is "oscillation with a slight upward bias", and the overall view is "wide - range oscillation".

The core logic is the conflict between short - term capital profit - taking intention and the fermentation of medium - and long - term policy positive expectations [1] Main Variety Price Market Driving Logic - Financial Futures Stock Index Sector - The intraday view for IF, IH, IC, and IM is oscillation with a slight upward bias, the medium - term view is upward, and the reference view is wide - range oscillation. Yesterday, all stock indices opened lower, oscillated throughout the day, and closed slightly lower. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2374.2 billion yuan, a decrease of 159.9 billion yuan from the previous day. Trump's sudden tariff threat on Friday increased external uncertainty risks before November, and investors' profit - taking intention rose due to the significant increase in stock index valuations. However, the impact of Trump's tariff threat on A - shares is short - term, and its marginal effect is weaker than that in early April this year. There are still problems of insufficient effective domestic demand and external tariff disturbances, but policy positive expectations strongly support stock indices. The investment attribute of A - shares is valued by the policy, and the trend of social wealth allocation to the stock market is emerging, with continuous capital inflows driving the repair of the valuation end of stock indices [5]

The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2534.1 billion yuan, a decrease of 137.7 billion yuan compared with the previous day. [5] - **Core Logic**: In the short term, due to the significant increase in stock valuation, the willingness of profitable funds to take profits has risen, and the marginal driving force of policy benefits will weaken. Coupled with Trump's threat to raise tariffs, the short - term stock market is under pressure, and there is a risk of a lower opening of the stock index on Monday. In the long term, policy - benefit expectations and the continuous inflow of funds still strongly support the stock index. The subsequent trend of the stock index focuses on the game between the fermentation of policy - benefit expectations and the profit - taking of profitable funds. [5]

The manufacturing PMI in September continued to recover, indicating strong resilience in the domestic macro - economy. Coupled with the expectation of favorable policies from important meetings in October, market risk appetite continued to rise. However, in the short term, due to the significant increase in the stock valuation, especially when the index rebounded near the previous high, there was still a demand for profit - taking by profitable funds. It is necessary to pay attention to the game between the subsequent profit - taking rhythm of funds and the fermentation of policy expectations. In general, since the index is close to the previous high, the stock index is expected to be mainly in wide - range oscillation in the short term [5]. Group 3: Summary by Related Catalogs Variety Viewpoint Reference - Financial Futures Stock Index Sector - The time - cycle is defined as short - term within one week, medium - term from two weeks to one month.

The core logic is that yesterday, each stock index oscillated widely and recovered after reaching the bottom. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 251.86 billion yuan, an increase of 37.6 billion yuan from the previous day. There is a certain divergence in market sentiment, focusing on the game between the profit - taking rhythm of funds and the fermentation of policy expectations. On one hand, there is still a demand for profit - taking of profitable funds; on the other hand, policy - favorable expectations and the net inflow trend of funds constitute the long - and medium - term driving force for the upward movement of the stock index. The fermentation of policy - favorable expectations depends on the October key meeting, and 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 significant increase in new non - bank deposits in July and August. In general, the stock index is expected to oscillate widely in the short term [5]
