Prediction and judgment. The sudden increase in turnover rate and trading volume of a certain stock may indicate that investors are buying in large quantities, and the stock price may rise accordingly. If a stock continues to rise for a period of time and then the turnover rate rapidly increases, it may imply that some profit seekers want to cash out, and the stock price may fall. Generally speaking, the turnover rate in emerging markets is higher than that in mature markets. The fundamental reason lies in the rapid expansion of emerging markets, the abundance of newly listed stocks, and the weak investment philosophy of investors, which makes trading in emerging markets more active. The principle of high turnover rate in trading 1. The sudden increase in trading volume at relatively high levels indicates a clear willingness of the main force to distribute. However, releasing trading volume at high levels is not an easy task. Generally, trading volume is released only when there are some favorable news, and the main force can successfully complete the distribution. There are many examples of this. 2. The focus of our discussion is on strong stocks with low bottom volume and low price. Their high turnover rate has a high degree of credibility, indicating that there are more obvious signs of new capital intervention, and the future upward space is relatively large. The more sufficient the bottom turnover, the lighter the selling pressure in the upward trend. 3. New stocks are a special group, and it is natural for them to have a high turnover rate at the beginning of their listing. There was once a myth of unbeaten new stocks, but with the changes in the market, it has become a reality for new stocks to open high and go low after listing.
