(B) Macro policies and news expectationsFrom the internal structure of the market, the phenomenon of plate differentiation is more prominent. The weighting sectors such as finance in early trading once drove the index to open higher, but the follow-up of other sectors was weak. On the one hand, science and technology growth sectors, such as artificial intelligence and semiconductors, which had a large increase in the previous period, are facing profit-taking pressure. With the recent gradual increase in the valuation of related sectors, some investors choose to lock in profits, and funds flow out of these high-valuation sectors, which has a certain impact on the overall popularity of the market. On the other hand, the traditional cyclical sectors, such as steel and coal, are relatively depressed due to multiple factors such as overcapacity, environmental protection policies and fluctuation of downstream demand, and failed to form effective support after the index opened higher, resulting in the lack of core driving force for sustained growth in the market, and finally moved towards a low trend.Second, the analysis of the reasons for high opening and low walking

Third, tomorrow's A-share market inferenceFrom the perspective of capital flow, if the market as a whole shows a rebound trend tomorrow, it is expected that some off-exchange funds will gradually flow in, especially the institutional funds that have been waiting and seeing in the early stage may increase the allocation of high-quality blue-chip stocks and leading enterprises in growth stocks. In the process of market decline, funds may flow from the high valuation plate to the low valuation defensive plate or the early oversold plate to seek hedging and arbitrage opportunities.(C) plate rotation and capital flow analysis

The tightness of funds has a key impact on the trend of A-share market. Recently, the overall market liquidity is in a relatively stable but not loose state, and the entry speed of incremental funds is relatively slow. After opening higher in early trading, due to the lack of sufficient follow-up funds, it is difficult for the market to maintain a high increase. At the same time, investors' mood changed greatly in the process of opening higher and then going lower in the morning. When the market opened higher, the optimism of the market briefly warmed up, but with the decline of the index, pessimism gradually gained the upper hand, which further aggravated the selling pressure of the market and formed a vicious circle, making it difficult for the index to obtain effective support and rebound during the decline.Second, the analysis of the reasons for high opening and low walking
