1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Today, all stock indices fluctuated and consolidated. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets throughout the day was 2777.6 billion yuan, a decrease of 52.5 billion yuan compared to the previous day. Currently, the trading volume of the stock market remains at a high level, indicating that the overall market sentiment is still relatively optimistic. In the short term, due to the significant increase in some stocks, there is a risk of technical adjustment caused by profit - taking of profitable funds, and there is a need for funds to rotate between high - and low - valued stocks. The main driving forces for this round of stock index rebound are the positive policy expectations and the loose liquidity in the capital market. Anti - involution policies and consumption - promotion policies promote the optimization of the supply - demand structure from both the supply and demand sides, leading to a moderate recovery of the price index and the repair of corporate profits. In terms of the capital market, the margin trading balance has risen rapidly, non - bank deposits have increased sharply, and long - term funds have continued to enter the market. The continuous inflow of incremental funds into the stock market has boosted the logic of stock valuation repair. Overall, the current market sentiment is generally positive, and the upward trend remains unchanged. However, there are some differences in the short - term market, and the stock index is expected to maintain a loose and volatile trend in the short term. - Currently, the implied volatility of options continues to rise. Considering the long - and medium - term upward trend of the stock index, investors can continue to hold bull spreads or ratio spreads for a moderate bullish view [3]. 3.

The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2709.8 billion yuan, a decrease of 467.1 billion yuan from the previous day.
