Stock market reversal refers to the reversal of the upward or downward trend of the stock market, which usually means that when the stock price rises, its trend falls briefly, and vice versa. This phenomenon usually attracts investors' attention, because it may indicate changes in market conditions and affect investors' decision-making. For example, the reversal of the upward trend can enable investors to restore profits or limit losses.

The stock market reversal may be caused by many factors, such as changes in the political and economic environment, market demand, economic data, company performance and so on. Usually, when the price of some stocks rises, some industries and the whole market they represent will prosper for a while, while other industries and markets may be relatively weak. When this trend begins to slow down or reverse, investors can re-evaluate the situation of industries and markets and formulate new investment strategies.

When the stock market reversal happens, investors may respond differently, depending on their risk preference and investment strategy. Some investors may buy on dips and expect the market to rebound, while others may choose to sell stocks and wait for the next trading opportunity. No matter what strategy is adopted, investors need to remain rational and calm at all times and make reasonable investment plans to cope with market changes.
