Formation of the Pattern
The Head and Shoulders Top is a common chart pattern in technical analysis. It belongs to the trend – reversal patterns and often appears near the end of an uptrend, indicating that the market trend will shift from upward to downward. The pattern consists of a left shoulder, a head, a right shoulder, and a neckline. In terms of stock price movement, it first rises to a certain height at the left shoulder and then falls back. Then it rises again to exceed the height of the left shoulder to form the head and falls back once more. Subsequently, it rises for the third time to around the height of the left shoulder to form the right shoulder and then drops. The pattern is confirmed when the price breaks below the neckline.
Formation Mechanism
Left Shoulder: The stock price continues to rise with a large trading volume. As investors take profits and start selling, the stock price drops back in the short – term. The trading volume during the decline is significantly less than that at the peak of the upward movement.
Head: After a brief decline, the stock price rises strongly with an increased trading volume. However, the peak trading volume is lower than that of the left shoulder. After the stock price breaks above the previous high, it falls back again, and the trading volume also decreases during this decline.
Right Shoulder: When the stock price drops back close to the previous low point, it gets supported and rebounds. But the market investment sentiment weakens, and the trading volume is significantly smaller than that of the left shoulder and the head. The stock price fails to reach the high point of the head and then falls back.
Neckline: A straight line connecting the low point of the left – shoulder decline and the low point of the head decline. When the stock price fails to rise for the third time and drops below the neckline, the Head – and – Shoulders Top pattern is officially established. Generally, the highest points of the left and right shoulders are approximately similar, and the highest point of the head is higher than that of the left and right shoulders.
Confirmation Methods
Pattern Confirmation: When the stock price breaks below the neckline and the closing price is lower than the neckline by a certain margin (such as 3%), and there is an increase in trading volume at the same time, the head-and-shoulders top pattern can be basically confirmed.
Technical Significance
Reversal pattern：The head-and-shoulders top pattern is a typical reversal pattern, indicating that the market trend will change from upward to downward.
The formation of the left shoulder represents a normal adjustment in the upward trend of the market and then continues to rise. The appearance of the head indicates that although the upward force in the market still exists, it has begun to face significant resistance, and the bullish force is gradually losing its advantage in the contest with the bearish force. The formation of the right shoulder shows that the bullish force has been significantly weakened, the market has difficulty rising, and the bearish force has begun to take the dominant position.
The stock price breaking below the neckline is a sign of the completion of the head-and-shoulders top pattern, which means a complete reversal of the market trend. Subsequently, the stock price often starts a relatively obvious downward trend.
Trading Strategies
For investors, they should be vigilant and gradually reduce their positions during the gradual formation of the head-and-shoulders top pattern. Once the stock price effectively breaks below the neckline, they should liquidate their positions in a timely manner to avoid losses caused by the subsequent significant decline in the stock price.
In addition, the target price range for the decline of the stock price can also be roughly estimated according to the height of the head-and-shoulders top pattern, that is, measure the vertical distance from the vertex of the head to the neckline, and then project the same distance downward from the neckline break point as the target area where the stock price may fall.
It should be noted that technical analysis is not absolutely accurate, and the head-and-shoulders top pattern may also fail. Therefore, in practical applications, it is necessary to combine other technical indicators and fundamental analysis methods to comprehensively judge the market trend to improve the accuracy of investment decisions.
Calculation Method
How to predict the potential decline of the stock price through powerful technical analysis?
(1) Measure the vertical distance from the vertex of the head to the neckline. As is shown in the chart, 54-35=10.
(2) Project the same distance downward from the neckline break point as the target area where the stock price may fall. As shown in the above chart. 35-10=25.
(3) The calculation of the equal-amplitude distance decrease. The target of the decrease is 15. 25-10=15.
In this chapter, we will analyze three cases. One is the foreign exchange trend of the US dollar against the Chinese yuan, another is the case of Best Buy’s stocks, and the last one is the case of Bitcoin.
How to predict the potential decline of the foreign exchange through powerful technical analysis?
- Measure the vertical distance from the vertex of the head to the neckline. As is shown in the chart, 7.3-7.1=0.2.
- Project the same distance downward from the neckline break point as the target area where the foreign exchange fall. As shown in the above chart, 7.1-0.2=6.9.
- At 6.7, there was no rebound at all, and the bears clearly held the upper hand. The calculation of the equal-amplitude distance decrease, and the bottom of the decrease is 6.7, 6.9-0.2=6.7.
Case2 BBY (2025, Daily Chart)
How to predict the potential decline of the stock price through powerful technical analysis?
(1) Measure the vertical distance from the vertex of the head to the neckline. As is shown in the chart, 103-80=23.
(2) Project the same distance downward from the neckline break point as the target area where the stock price fall. As shown in the above chart, 80-23=57.
Case2 BTC (2021-2022, Daily Chart)
How to predict the potential decline of the Bitcoin price through powerful technical analysis?
- Measure the vertical distance from the vertex of the head to the neckline. As is shown in the chart, 68000-27500=40500.We can observe that at the neckline, the forces of the bulls and the bears engaged in repeated tug-of-wars.
- Project the same distance downward from the neckline break point as the target area where the stock price fall. As shown in the above chart, 40500-27500=13000. Although the price of Bitcoin didn’t drop to 13,000, it was still very close to that level.
