Recently, I’ve noticed many people losing money trading stocks, and the root cause is actually very simple— they don’t understand turnover rate at all. Today, I’m going to break down this most practical concept for everyone, and I believe after reading this, you’ll have a sudden realization.

First, let’s start with the basics: the turnover rate is the frequency of stock trading, reflecting how active this stock really is. For example, if a stock trades 10 million shares in a month, with a total share capital of 100 million shares, then the turnover rate is 10%. It sounds simple, but there’s a lot hidden behind this number.

Why do I say that the turnover rate is the best way to find the main players? Because the level of turnover rate directly reflects the flow of funds. In my practical experience, I’ve found that stocks in different turnover rate ranges behave completely differently. For instance, stocks with a 1%-3% turnover rate are generally ignored—institutions don’t look at them, retail investors don’t favor them, and these stocks are like dead water. But when the turnover rate rises to 3%-5%, people start tentatively building positions, which is a signal.

What’s really interesting is the 5%-7% range. Both bulls and bears begin to have disagreements, and the stock price slowly rises, which is very likely the main force gradually accumulating shares. My experience is that at this point, you need to pay close attention. If the turnover rate continues to stay between 7%-10%, then the buying by the main players is more aggressive.

Here’s the key—when the turnover rate reaches 10%-15%, the main force’s intention to control the stock becomes very obvious. The strength of accumulation is increasing, and once the accumulation is complete, a rally isn’t far off. But you need to be cautious: if this happens at a low price level with increased volume, that’s a true sign of a bottoming out. Conversely, if volume increases at a high level and the price drops, I personally would never intervene.

When the turnover rate hits 15%-20%, trading becomes quite active, and volatility increases. If the stock price is still at a low level, it might be the main force violently accumulating shares; if it’s already at a high level, then be alert—possibly they’re distributing. Here’s a detail: don’t just watch the large orders; today’s main players have learned to split big orders into small ones to sell gradually—reducing friction costs and preventing retail investors from panicking and selling off.

Once the turnover rate exceeds 20%, the situation becomes more complicated. Between 20%-30%, if at a low level, the main force might be aggressively accumulating to attract retail investors; if at a high level, it’s likely distributing. A turnover rate of 30%-40% usually appears only in stocks with very hot themes, and it’s very likely the main force is offloading, swapping chips with new buyers.

When the turnover rate reaches 40%-50%, the stock’s attention is extremely high, with large fluctuations in price. Most people can’t hold on, and the risk is huge—I advise everyone to be cautious when entering. Over 50%-60%, it’s an extremely crazy state, with buyers and sellers cursing each other. If this occurs at the bottom, it might be a sign of major good news; if at the top, it’s the previous profit-takers selling, and new buyers trying to catch the bottom—often ending in tragedy.

Let me share a core practical logic. Volume increase at a low level is worth paying attention to; volume decrease at a high level, I would never personally intervene. More importantly, when a stock keeps falling, never try to catch a falling knife. If I like a stock, I’ll wait until it stabilizes before entering from the right side. Be cautious when needed, don’t go against the trend—that’s my respect for the market.

Finally, I want to mention a point many people overlook. Stocks with low turnover rates sometimes can continue to rise in price, indicating that medium- to long-term main players are operating. Such stocks tend to have strong sustainability and lower risk. But if a stock is moving in a downward channel and suddenly the turnover rate drops sharply, with no trading activity—especially after the main force has built a position and then shaken out the stock—then you should pay close attention, because the stock price might have already bottomed out.

In summary, learning to read the turnover rate gives you the key to identifying the main players. But remember, the turnover rate is just a tool; you also need to consider the stock’s position, the overall market condition, and the theme’s heat. Blindly trusting the turnover rate alone can also lead to pitfalls.
