This is the thirteenth part of a series of articles about technical analysis from a new course we're developing. If you are new to charting, these articles will give you the “big picture” behind the charts on our site. If you are an “old hand”, these articles will help ensure you haven't “strayed too far” from the basics. Enjoy!
Tip. See the entire series Technical Analysis 101
One of the most common reversal patterns is the Head and Shoulders pattern.
This pattern forms in an uptrend and its completion marks a trend reversal. The pattern contains three successive peaks with the middle peak (head) being the highest and the two outside peaks (shoulders) being lower. The reaction lows of each peak can be connected to form a line of support called a neckline. The top reversal pattern is completed when price breaks below the neckline.
While it is preferable that the left and right shoulders be symmetrical, it is not an absolute requirement. They can be different widths as well as different heights.
It's important to realize that up until the point where prices move back below the level of the left shoulder, things look like a normal, ongoing uptrend. It is only when the left shoulder's price level is violated that the bulls become fearful and the bears start to smell blood. The right shoulder forms as the bulls try to reestablish the uptrend and then fail - usually because many of the more skittish investors will take profits at that point.
As the Head and Shoulders top reversal pattern unfolds, volume plays an important role in confirmation. Buying volume (volume on up days) will slowly translate into selling volume (volume on down days) as the pattern develops. This is seen when volume that previously expanded on rallies begins to expand on declines and contract on rallies.
The Head and Shoulders bottom reversal pattern is just the reverse of the top reversal pattern with volume acting as a confirmation.
As with the Head and Shoulders top reversal pattern, volume action is helpful in confirming the trend reversal. Volume that was previously expanding on declines begins to expand on rallies and contract on declines as the trend reversal develops.
Traders begin noticing lighter selling volume on the declines and heavier buying volume on the rallies. This kind of price and volume action is quickly noticed by the market which results in additional buying volume supporting the trend reversal.
A couple of other comments about this pattern:
Sometimes several left shoulders will form before a true head appears. Sometimes several right shoulders appear before a true neckline break occurs.
When a neckline break occurs, the stock will often fall at least as much as the distance from the neckline to the top of the head.
Many of the technical analysis books out there will go on to talk about several other kinds of reversal patterns - the rounding bottom, the V-reversal, double tops, triple bottoms, and others. (We have many of them cataloged in our ChartSchool area.) Here's a trade secret - most of those are just variations of the Head and Shoulders reversal pattern that didn't form “perfectly” for some reason. For example, the Triple Top is a Head and Shoulders pattern where the head doesn't go above the left shoulder.
The key point here is this - don't worry about what type of reversal is occurring. Knowing it's a Triple Top instead of a Head & Shoulders won't make you more money. Focus on what the chart is telling you—the fear/greed ratio is changing—and react accordingly.
In part 14, we'll look at the question “How much is too much?"
