在股票交易中，有一个非常重要的指标叫做换手率。换手率指的是一定时间内股票转手买卖的频率，也就是股票流通量的交易比例。换手率的计算公式为：换手率=成交量/流通股本×100%。

换手率的重要性在于它能够反映出股票的活跃程度和市场的交易情况。一般来说，换手率高说明市场交易活跃，投资者买卖意愿较强；而换手率低则表明市场交易不活跃，投资者买卖意愿不强。对于投资者来说，换手率的高低可以帮助他们判断股票的走势和市场的行情。

除了反映市场的交易情况，换手率还与主力资金的运作有关。如果一只股票的换手率突然增大，那么很有可能是主力资金在运作，这时投资者可以关注该股票是否有上涨潜力。另外，换手率也是衡量一个股票流通性强弱的重要指标，对于投资者来说也是非常重要的参考数据之一。

总之，换手率是股票交易中非常重要的一个指标，它能够反映出股票的活跃程度、市场的交易情况和主力资金的运作情况。对于投资者来说，关注换手率的高低能够帮助他们更好地把握股票的走势和市场的行情。

In stock trading, there is a very important index called the turnover rate. The turnover rate refers to the frequency of stock transactions within a certain period of time, which is the trading proportion of the circulating capital. The formula for calculating the turnover rate is: turnover rate = trading volume / circulating capital × 100%.

The importance of the turnover rate lies in its ability to reflect the activity level of stocks and the trading situation of the market. Generally speaking, a high turnover rate indicates active market trading and strong investor willingness to buy and sell; while a low turnover rate indicates inactive market trading and weak investor willingness to buy and sell. For investors, the level of turnover rate can help them determine the trend of stock prices and the market conditions.

In addition to reflecting the market's trading situation, the turnover rate is also related to the operation of major funds. If the turnover rate of a stock suddenly increases, it is likely that major funds are operating, and investors can focus on whether the stock has potential for growth. In addition, the turnover rate is also an important indicator for衡量一个stock's liquidity, which is also one of the important reference data for investors.

In summary, the turnover rate is a very important index in stock trading. It can reflect the activity level of stocks, the market's trading situation, and the operation of major funds. For investors, focusing on the level of turnover rate can help them better grasp the trend of stock prices and the market conditions.
