Against the backdrop of positive policy expectations, technology - related stocks rose significantly [3]. - The easing of external uncertainty risk factors brought about by China - US economic and trade consultations led to a recovery in investors' risk appetite, causing the stock indices to rebound from the bottom.

Group 1: Report Industry Investment Rating - No relevant content found Group 2: Core Viewpoints - Today, all stock indices showed a trend of hitting bottom and rebounding. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets throughout the day was 1660.7 billion yuan, a decrease of 29.7 billion yuan compared to the previous day. The shrinking trading volume in the stock market indicates that market sentiment is cautious. On the news front, China and the United States will hold economic and trade consultations in Malaysia from October 24th to 27th, which has reduced risk aversion and improved market sentiment. As the valuation of some stocks has increased significantly, the marginal expectation of incremental policy benefits at the end of the year has slowed down, and there is still a need for profit - taking in the capital market. In the short term, the changing rhythm of the game between the profit - taking intention of funds and the expectation of policy benefits will dominate the trend of stock indices within the year. In general, stock indices are expected to fluctuate widely in the short term [3]. - Currently, the implied volatility of options remains relatively stable.

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.

Report Industry Investment Rating - No relevant content provided Core Viewpoints - Today, all stock indices oscillated and rebounded. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.0904 trillion yuan, a decrease of 506.2 billion yuan from the previous day. The volume - shrinking rebound of the stock market reflects that the overall market sentiment remains optimistic, with funds entering the market on dips after corrections, and the downside space for stock indices is limited. At the same time, it also shows that funds chasing higher near the previous high points remain relatively cautious [4]. - In the short term, the tariff war has resurfaced, and external uncertainties have increased before November. Coupled with the current relatively high valuation level, investors' willingness to take profits has risen, and there is short - term technical correction pressure. In the medium to long term, the problem of insufficient effective domestic demand still exists, and the disturbance of external tariff factors still remains. There are strong expectations for policy - makers to stabilize the macro - fundamentals, and the expectation of policy benefits forms strong support for the stock indices. The trend of net capital inflow into the A - share market remains unchanged, so the stock indices have strong medium - to - long - term support. Overall, under the game between profit - taking sentiment and policy support, the stock indices are expected to maintain wide - range oscillations in the short term [4]. - Currently, the implied volatility of options remains relatively stable. Considering the medium - to - long - term upward trend of the stock indices, investors can continue to hold bull spreads or covered calls [4].
