Recently, while analyzing stocks, I discovered that many beginners actually don't understand a fundamental concept — turnover rate. It looks simple, but mastering it can help you identify the main players' movements and even avoid many pitfalls.

Let's start with the most straightforward understanding. The turnover rate is the frequency of stock trading, reflecting how active a stock is. Think about it: if a stock has no trading activity and its volume is dead, obviously no one is paying attention. Conversely, if the turnover rate is particularly high, it indicates that both buyers and sellers are trading frequently, and the stock's activity level is high.

The official definition is: Turnover rate equals the trading volume over a certain period divided by the circulating shares, then multiplied by 100%. For example, if a stock's monthly trading volume is 10 million shares and the circulating shares are 20 million, the turnover rate is 50%. This number directly reflects the stock's liquidity.

But here's where it gets interesting — different levels of turnover rate correspond to completely different stock states. I’ve summarized a method for judging these levels.

1%-3%: Honestly, this is dead silence. Institutions don't look at it, retail investors aren't interested either. It might be because the market cap is too large to move easily, or the theme is too traditional and unappealing.
3%-5%: Some tentative positions are being built, but activity remains low.
5%-7%: There are disagreements between bulls and bears, and the stock price is gradually rising, possibly indicating that the main players are quietly accumulating shares.
7%-10%: Main players are actively buying. If the price is falling at this point, it could be a shakeout, but the moves are still relatively light.
10%-15%: This is a critical zone. The main players are trying to control the stock, increasing their accumulation efforts. Once they've gathered enough, a rally isn't far off.
15%-20%: Trading becomes more active, and volatility increases. If the stock is still at a low level with high volume, it might be a pre-launch signal worth watching. But if it’s high and falling on high volume, be cautious.
20%-30%: The battle between bulls and bears is very intense. At low levels, the main players might be aggressively accumulating shares to attract retail investors; at high levels, it could be distribution.
30%-40% and above: Very high turnover rates. Only stocks with particularly hot themes reach this level. Usually, main players prefer to accumulate quietly because obvious signs can push the stock price up prematurely, increasing their purchase costs. Such high turnover might indicate that the main players are transferring shares to the next hand.
50%-60% and above: Extremely intense attention, with large price swings. Most people can't hold on.
70%-80%: Already off the normal track, with huge uncertainty. In a downtrend, I advise against catching falling knives, as there might be negative news you're unaware of. The decline tends to be persistent, and after such high turnover, the volatility is likely to continue.
80%-100%: Nearly all shares are changing hands, and market sentiment is at its peak. These stocks should be observed from afar; avoid playing with them, wait until things calm down.

In practical trading, what’s most valuable? Volume increasing at low levels is worth noting. Volume increasing at high levels and then falling is something I personally avoid. When I like a stock, I wait until it stabilizes before entering from the right side. Don’t fight the trend; be respectful of the market.

Another core point — don’t just look at the turnover rate number. Pay attention to where it appears. If after a long period of stagnation, a high turnover rate suddenly appears and can be maintained for several trading days, it indicates new funds are coming in. This kind of high turnover is more credible because it involves volume at the bottom and thorough transfer of shares, suggesting the stock has a good chance of rising and becoming a strong stock.

Conversely, if a stock is in a downtrend and the turnover rate is very low, with little buying or selling, especially after the main players have built positions and then shaken out the stock, this signals that the stock is already at a bottom zone and warrants close attention.

Finally, high turnover rate doesn’t always mean a good sign. When a stock has risen sharply and is far from the main players’ cost basis, a high turnover rate can actually be a sign of distribution. We often say “massive volume at sky-high prices,” which describes this situation. During an uptrend, maintaining a steady, high turnover rate is essential. Once the turnover rate drops, it indicates that the funds behind the high prices are leaving, and the upward momentum will weaken.

So, truly skilled users of the turnover rate don’t just look at how high it is; they analyze its position relative to the stock price, how long it lasts, and the overall market environment. This comprehensive approach is the correct way to identify main players’ movements and seize market opportunities.
