Recently, while studying technical analysis, I recalled the classic pattern of the Head and Shoulders. To be honest, this chart looks simple, but if you truly understand it thoroughly, it can be very helpful in predicting turning points in stock prices.

Let's start with the Head and Shoulders. In simple terms, it’s a pattern where, during an uptrend, three relatively high points form: the left shoulder, the head, and the right shoulder, with the head being the highest. This pattern often indicates that the stock price may reverse downward. Why is that? Let me break down the entire process.

The stock price first reaches a high point, which is the position of the left shoulder. At this time, some investors start taking profits, but others remain optimistic about the future, so the price slightly pulls back. The lowest point of this pullback is called the neckline, an important support level. Then, the price begins to rise again, this time higher, forming the head. But as the price climbs higher, buying momentum gradually weakens, and selling pressure increases, causing the price to fall. When the price drops back to near the neckline, another wave of buyers enters, mostly those who bought at lower levels, aiming to break even. However, this rebound’s high point—the right shoulder—cannot surpass the previous high of the head. At this point, a complete Head and Shoulders pattern is officially formed.

Next comes the critical moment. If the price continues to fall and breaks below the neckline, it’s a clear sell signal. The neckline, which previously served as support, will turn into resistance. Many investors tend to exit near their cost basis at this point to avoid further losses. Any rebound might be a chance to escape, and it’s unwise to hold onto the hope that it will turn back.

I remember Tencent as a very typical example. It rebounded starting at the end of 2022, formed the head in late January 2023, and the right shoulder in late March, then the stock began to weaken. When it broke below the neckline at the end of April, the price was around 360 yuan, still some distance from the high of 415 yuan. But if they hadn’t sold then, over the next nearly year, the stock never exceeded 360 yuan and finally stayed below 200. By the end of 2023, Tencent had a rebound opportunity, but the Chinese government suddenly announced policies to crack down on online gaming, causing the stock to plunge 12.3%, completely destroying the pattern. This case shows us that missing the signal given by the Head and Shoulders pattern means you can only exit at a much lower price later.

For traders who like to short, the Head and Shoulders pattern is also a good entry point. But shorting differs from simply selling; it requires constant monitoring of when to close the position. The entry point is when the price breaks below the neckline. The exit point should pay special attention to the neckline—once the price rebounds and breaks above it, you should close immediately, regardless of profit. If the price hasn’t broken the neckline, you can set a take-profit level. A common approach is to use the distance from the entry point to the head as a reference. For example, in Tencent’s case, the head was at 415, the entry at 360, a difference of 55 points, so the take-profit could be set at 305. In practice, short positions entered in April and exited in May, reaching the take-profit level within just a month.

However, there is a symmetrical pattern called the Head and Shoulders Bottom, which is basically the upside-down version of the Head and Shoulders Top. It signals a bullish trend. Selling pressure weakens, and new buyers flood in, causing the price to bottom out. The left shoulder of the Head and Shoulders Bottom is the last rebound before the bottom forms. During the decline, there are multiple rebounds, but no one knows which one is the true bottom. As more people stop-loss out, more start to buy the dip, and the price begins to rebound.

The head of the Head and Shoulders Bottom is the lowest point of the downtrend. At this position, trading volume is usually very small because most sellers have already sold. Small buy orders at this point can push the price sharply higher. If the price can break through the neckline resistance directly, it’s called a V-shaped reversal. If not, a right shoulder may form.

The appearance of the right shoulder indicates that an upward signal is about to be confirmed. Because the lows are higher than the previous lows, it shows that there are buy orders protecting the market—these buyers are optimistic about the future or are short covering. In any case, these buy orders reduce selling pressure and increase upward momentum. If the price can break through the neckline resistance, that level will turn into support.

For the Head and Shoulders Bottom pattern, there are generally two buy signals. One is to buy directly after the right shoulder is confirmed, as the gradually rising lows suggest higher highs. The other is to buy after the price breaks through the neckline, as the upward trend is already confirmed and market resistance is lower. The first signal allows entering at a cheaper price with higher risk but greater potential reward; the second has lower risk but might miss the lowest point.

Setting stop-loss and take-profit levels is also important. If entering at the neckline price, you can set the stop-loss at the right shoulder’s price; if entering at the right shoulder, you can use the head’s price as a stop-loss. Profit targets vary by individual, but short-term traders often recommend setting a take-profit at 2 to 3 times the stop-loss distance. Even with a win rate of only 30%, this can still be profitable on average.

But I want to emphasize that technical analysis patterns are just tools to improve win probability; they cannot guarantee profits 100%. Fundamental changes can directly invalidate the pattern, just like the Tencent example. Also, assets with very low trading volume are less suitable for pattern analysis because the sample size is too small, making statistical results unreliable. Larger stocks and indices are more appropriate for pattern-based analysis.

Therefore, Head and Shoulders and related technical patterns are only reference indicators, telling you that statistically, when such situations occur, there’s a high probability of a certain trend. But you shouldn’t blindly believe the pattern will always play out as shown. To improve trading success, it’s essential to combine technical analysis with fundamentals, market sentiment, capital flow, and other factors.
