sometimes the turnover rate of stocks can explain everything (active trading), and sometimes it is useless. (The main force can slowly build positions in the bottom 5 lots and 8 lots, or distribute stocks in the top 1 lots and 2 lots), and judging the ups and downs by the turnover rate alone is one of the reasons why retail investors eat it again and again. A little experience, it is important that the turnover rate is only an indicator to judge the trend, and it is by no means a panacea.
