The Shanghai Stock Exchange 50 Index rose slightly after a rise and fall throughout the day, while the CSI 500 and CSI 1000 showed weak performance and closed slightly lower. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2,306.3 billion yuan, an increase of 131.1 billion yuan from the previous day. The high trading volume indicates an optimistic market sentiment. In the short term, due to the profit - taking demand of profitable funds after continuous rises, the stock index may experience short - term technical consolidation. However, the positive policy expectations strongly support the stock index. Anti - involution and consumption - promotion policies are conducive to promoting a moderate recovery of the price index, restoring the profit margins of listed companies, and promoting a positive cycle in the "residents' consumption - corporate profits - employee salaries" chain, leading to an increasing expectation of an improving macro - economic fundamentals. Overall, in the short term, the domestic policy expectations are positive, external risk factors are temporarily alleviated, the risk appetite of the stock market continues to recover, and the stock index will mainly show a volatile and upward trend. Currently, the implied volatility of options has rebounded. Considering the long - term upward trend of the stock index, investors can continue to hold bull spreads or ratio spreads to maintain a moderately bullish view [2] 3.
