Recently, I’ve noticed that many novice traders get stuck on one problem: they don’t know how to determine whether a stock is cold or hot. Actually, there’s a very straightforward indicator that most people overlook — the turnover rate.

Honestly, looking at the turnover rate seems simple, but not many people truly understand it thoroughly. Today, I’ll break down this concept and explain it clearly to everyone.

In short, the turnover rate is the frequency of buying and selling a stock, reflecting how active that stock is. The calculation is also simple: trading volume over a period divided by the circulating shares, multiplied by 100%. For example, if a stock trades 10 million shares in a month, and the circulating shares are 20 million, then the turnover rate is 50%.

Why should you pay attention to this indicator? Because it helps you identify the actions of the main players. The meaning of the turnover rate varies greatly across different ranges. Stocks with a turnover rate of 1% to 3% are basically ignored—institutions don’t care, retail investors aren’t interested. Either it’s a large-cap stock that’s not moving, or the theme is too old. When the turnover rate hits 3% to 5%, some tentative positions start to form. Between 5% and 7%, both bulls and bears begin to have differing opinions; the stock price slowly moves upward, which often signals that the main force is quietly accumulating shares.

The higher it goes, the more interesting it gets. When the turnover rate reaches 7% to 10%, the main buyers become noticeably active. If the stock price drops at this point, it could be a light shakeout by the main force. Between 10% and 15%, the main players want to control the stock, increasing their accumulation efforts. After this stage, a rally is likely imminent. When the turnover rate hits 15% to 20%, trading becomes more active. If it’s at a low price with volume, it might be about to start a move.

But here’s a crucial turning point. When the turnover rate exceeds 20%, especially in the 30% to 40% range, you need to be very cautious. Such levels of turnover are usually only seen in stocks with very hot themes. If this occurs at a low price, the main force might be aggressively accumulating shares to attract retail follow-on. But if it happens at a high price, it’s a warning sign of distribution. Today’s main players are smart—they often split large orders into smaller ones to sell gradually, reducing costs and preventing retail investors from panicking and dumping.

A turnover rate of 40% to 50% is very dangerous; such stocks carry high risk. Between 50% and 60%, it gets even crazier—possibly triggered by some news causing huge divergence. At high levels, those who sell are taking profits, while buyers are trying to catch the bottom. From 60% to 70%, it’s basically an extremely frantic state, with buyers and sellers cursing each other. Between 70% and 80%, it’s off the rails; the stock’s uncertainty is huge. If it’s falling, I strongly advise you not to catch the falling knife, as there may be unknown negative news. When the turnover rate hits 80% to 100%, almost all the chips are changing hands, and market sentiment is at its peak frenzy. My suggestion is: only observe from a distance, don’t try to play.

How to interpret the turnover rate most effectively? The key is to see where it appears. Low-price stocks with high turnover are the most worth watching, especially if after a long period of stagnation, they suddenly show high turnover and maintain it for several trading days. This usually indicates new funds entering. Because it’s volume at the bottom with full turnover, the stock probably has good upside potential and may become a strong stock.

Conversely, high-price stocks with high turnover should raise caution. If the stock price has risen sharply and is far from the main players’ cost basis, high turnover at this point often signals distribution. We often say “massive volume at sky-high prices,” which refers to this situation.

Another very important detail: if a stock has a very low turnover rate but the price keeps rising, it indicates that medium- to long-term main forces are operating. Such stocks tend to be more persistent and carry lower risk. In contrast, stocks with high turnover are often chased by short-term funds, highly speculative, with large price swings and higher risk.

In practical experience, I find that a turnover rate below 3% is quite normal, indicating no big capital involvement. Between 3% and 7% warrants attention. Daily turnover of 7% to 10% is often seen in strong stocks, showing high activity. If it’s between 10% and 15%, unless at a historical high or topping phase, it suggests that a strong institutional player is actively operating. Over 15% daily turnover, if maintained near intense trading zones, could mean huge upward potential—characteristic of super-strong institutional control.

I also pay close attention to stocks with several consecutive days of high turnover, especially when combined with large price increases that outperform the market significantly. This phenomenon can have multiple interpretations: it might be main force raising the stock, short-term speculative chasing, or old institutional players distributing. It’s important to combine this with other factors for further judgment.

Finally, I want to emphasize that the level of turnover rate often reflects the stock’s trading activity. High turnover indicates good liquidity, easy entry and exit, but also higher risk. Low turnover suggests low attention, often in obscure stocks. By combining turnover rate with price trends, you can make more reliable predictions about future stock movements.

In summary, understanding how to read the turnover rate is essential for interpreting the stock market. It’s the most direct way to identify the actions of the main players and the most effective tool for gauging stock activity. Once you truly grasp what the different levels of turnover rate represent at various positions, you’ll avoid many pitfalls.
