The price chart reflects the fluctuations of investors’ levels of optimism over time. Looking at their ups and downs, we can say something about what they think and feel. And thus something about what they will do next.
Certain patterns, called price formations, can be explained by precise descriptions of the investors’ psychological state. When these patterns are formed in price charts, clear buy or sell signals are triggered. Identification of and trading from price formations are very central to technical analysis.
Investtech has created computer programmes that identify formations and plot them in charts. Buy signals are shown as green arrows and sell signals as red arrows. The height of the arrows denotes expected price movement.
A buy signal from a rectangle formation signals increasing optimism among investors and signals that the stock continues or enters a rising trend.
A stock that has triggered a buy signal from a rectangle formation is indicated to rise further. This is especially the case when the stock price is already in a rising trend channel. Investors have experienced a positive surprise which has triggered the signal, and optimism is on the increase.
Volume is a good indicator of the strength of the buy signal. High volume on rising prices indicates that aggressive buyers keep paying more in order to buy. This is positive for further development. High volume and positive volume balance will strengthen a buy signal.
Rectangle formations are usually continuing formations. This means that the price usually continues in the long term direction, or the long term trend, it was in before the formation. Rectangle formations that trigger buy signals in rising trends are therefore seen to give stronger signals than rectangle formations that trigger buy signals in falling trends.
Small rectangle formations can trigger false buy signals. This is especially the case when the formation is small, when the stock remains in a falling trend channel, and when volume development is negative. At buy signal from a rectangle formation the stock as a whole should be assessed, not solely the buy signal. Many investors have bought long term losers too soon following weak buy signals from rectangle formations. The following applies:
Stocks with these positive signals have on average outperformed the market in the following months. Annualised excess return has been 9.0 percentage points (pp). This is significantly better than benchmark.
Annualised return (based on 66-day figures) | |
Positive signals medium term | 19.8% |
Reference index | 10.8% |
Excess return | 9.0pp |
The research results are based on 3368 signals from Nordic stocks in the period 2008-2020.
A sell signal from a rectangle formation signals increasing pessimism among investors and signals that the stock continues or enters a falling trend.
A stock that has triggered a sell signal from a rectangle formation is indicated to fall further. This is especially the case when the stock price is already in a falling trend channel. Investors have experienced a negative surprise which has triggered the signal, and the level of fear is increasing.
Volume is a good indicator of the strength of the sell signal. High volume on falling prices indicates that aggressive sellers keep reducing the price in order to sell. This is negative for further development. High volume and negative volume balance will strengthen a sell signal.
Rectangle formations are usually continuing formations. This means that the price usually continues in the long term direction, or the long term trend, it was in before the formation. Rectangle formations that trigger sell signals in falling trends are therefore seen to give stronger signals than rectangle formations that trigger sell signals in rising trends.
Small rectangle formations can trigger false sell signals. This is especially the case when the formation is small, when the stock remains in a rising trend channel, and when volume development is positive. At sell signal from a rectangle formation the stock as a whole should be assessed, not solely the sell signal. Many investors have sold long term winners too soon following weak sell signals from rectangle formations. The following applies:
Stocks with these negative signal have on average underperformed compared to benchmark in the following months. Annualised negative excess return has been 6.6 percentage points (pp). This is significantly weaker than benchmark.
Annualised return (based on 66-day figures) | |
Negative signal medium term | 4.3% |
Reference index | 10.9% |
Excess return | -6.6pp |
The research results are based on 2677 signals from Nordic stocks in the period 2008-2020.
A rectangle formation marks a market consolidation. The longer the formation is developing, the higher pressure builds among the investors. When the formation is broken, a strong price movement in the same direction tends to happen.
Buy signals from such formations have given statistically good results, according to Investtech’s research report for several stock exchanges.
Pay attention when rectangle formations are developing. Strong buy signals can follow, especially if the price is also in a rising trend and volume development is positive. Breaks downward give strong sell signals, especially when the price is also in a falling trend and volume development is negative.
A buy signal from an inverse head and shoulders formation signals increasing optimism among investors and the beginning of a rising trend. Formations like this are considered some of the most reliable formations in technical analysis.
An inverse head and shoulders formation is a bottom formation which marks the end of a falling trend. The formation consists of a left shoulder, a head and a right shoulder, connected by a neckline. The buy signal is triggered when the price breaks upwards through the neckline heading up from the right shoulder.
On the left shoulder investors are negative. The trend is falling and it does not look good for the company. As the pessimism wanes, the head is formed. Here the stock might break out from a falling trend channel and buyers become more aggressive or sellers more passive. On the right shoulder, the pessimists are unable to push the price downwards to a new bottom. Instead buyers push the price upwards through the neckline and the buy signal is triggered. The stock breaks upwards through resistance at the neckline and a rising trend begins.
A stock that has triggered a buy signal from an inverse head and shoulders formation is indicated to continue rising, for at least as long as the formation is high.
Please note that false buy signals from small inverse head and shoulders formations may arise in long term falling trends. Sometimes these can be spotted by a reduction in volume on the break. This indicates little strength in the price movement, and the stock can easily break down again and continue the falling trend. In such situations it can be advantageous to keep the stock and wait to see what happens also after the buy signal. This is especially the case if the stock is still in a falling trend or faces resistance from previous tops.
Sometimes good indicators of a coming break exist before the neckline is broken. Volume reduction on or towards the bottom of the right shoulder indicates that the sellers are passive. Increasing volume on the way up from the head or up from the right shoulder indicates that buyers are aggressive. Aggressive buyers and passive sellers are a good mix and a clear indication of increasing optimism in the stock and a coming break upward. In such situations it can be advantageous to buy before the buy signal is triggered.
Stocks with these positive signals have on average outperformed the market in the following months. Annualised excess return has been 4.3 percentage points (pp). This is significantly better than benchmark.
Annualised return (based on 66-day figures) | |
Positive signals medium term | 14.0% |
Reference index | 9.7% |
Excess return | 4.3pp |
The research results are based on 1212 signals from Nordic stocks in the period 2008-2020.
A potential inverse head and shoulders formation is developing. It may trigger a strong buy signal.
Signals from such formations are considered some of the strongest buy signals in technical analysis. Please note that such a signal may be triggered soon. In some situations it may be advantageous to sell before the buy signal is triggered, as this gives a much bigger upside.
Important indicators of a developing break upwards are:
However, if volume development is negative and the stock remains in a falling trend, it indicates fear among investors and further negative development for the stock.
A sell signal from a head and shoulders formation signals increasing pessimism among investors and the start of a falling trend. Formations like this are considered some of the most reliable formations in technical analysis.
A head and shoulders formation is a top formation which marks the end of a rising period. The formation consists of a left shoulder, a head and a right shoulder, connected by a neckline. The sell signal is triggered when the price breaks downwards through the neckline heading down from the right shoulder.
At the left shoulder, investors are optimistic. The trend is rising and things are looking good for the company. Optimism is reduced when the head is formed. Here the stock might break out from the trend channel and buyers become more passive or sellers more aggressive. At the right shoulder, the optimists are unable to push the price upwards to a new top. Instead sellers push the price downwards through the neckline and a sell signal is triggered.
The stock breaks support at the neckline and a falling trend begins. A stock that has triggered a sell signal from a head and shoulders formation is indicated to continue falling, for at least as long as the formation is high.
Please note that false sell signals from small head and shoulders formations may arise in long term rising trends. Sometimes these can be spotted by a reduction in volume on the break. This indicates little strength in the price movement, and the stock can easily break upwards again and continue the rising trend. In such situations it can be advantageous to keep the stock and wait to see what happens also after the sell signal. This is especially the case if the stock is still in a rising trend or has support from previous bottoms.
Sometimes good indicators of a coming break exist before the neckline is broken. Volume reduction on or towards the top of the right shoulder indicates that the buyers are passive. Increasing volume on the way down from the head or down from the right shoulder indicates that sellers are aggressive. Passive buyers and aggressive sellers are a bad mix and a clear indication of increasing pessimism in the stock and a coming break downward. In such situations it can be advantageous to sell before the sell signal is triggered.
Stocks with these negative signal have on average underperformed compared to benchmark in the following months. Annualised return has been 1.0 percentage points (pp) weaker than benchmark.
Annualised return (based on 66-day figures) | |
Negative signal medium term | 8.3% |
Reference index | 9.3% |
Excess return | -1.0pp |
The research results are based on 1444 signals from Nordic stocks in the period 2008-2020.
A potential head and shoulders formation is developing. It may trigger a strong sell signal.
Signals from such formations are considered some of the strongest sell signals in technical analysis. Please note that such a signal may be triggered soon. In some situations it may be advantageous to sell before the sell signal is triggered, to avoid the risk of a bigger loss.
Important warning signs are:
However, if volume development is positive and the stock remains in a rising trend, it indicates optimism among investors and further positive development for the stock.
A buy signal from a double bottom formation signals increasing optimism among investors and the beginning of a rising trend.
A double bottom formation is a bottom formation which marks the end of a falling period. The formation consists of two bottoms of about the same depth. The buy signal is triggered when the price breaks upwards above the bottoms.
At the first bottom the investors are pessimistic. There is a falling trend and things are not looking good for the company. As the second bottom is formed, the pessimism is reduced. Many are positively surprised when the stock does not fall below the previous bottom, and thus might not continue the falling trend. When the price breaks above the top between the bottoms, it breaks the resistance located there. Pessimism has been replaced with dawning optimism and a rising trend has begun.
A stock that has triggered a buy signal from a double bottom formation is indicated to rise further, for at least as much as the formation is high.
Double bottom formations trigger false buy signals fairly often. This is especially the case when the formation is small, when the stock remains in a falling trend channel, and when volume development is negative. At buy signal from a double bottom formation the stock as a whole should be assessed, not solely the buy signal. Many investors have bought losing stocks too soon following weak signals from double bottom formations. The following applies:
Stocks with these positive signals have on average underperformed compared to benchmark in the following months. Annualised return has been 2.0 percentage points (pp) weaker than benchmark.
Annualised return (based on 66-day figures) | |
Positive signals medium term | 7.5% |
Reference index | 9.5% |
Excess return | -2.0pp |
The research results are based on 2317 signals from Nordic stocks in the period 2008-2020.
A sell signal from a double top formation signals increasing pessimism among investors and the beginning of a falling trend.
A double top formation is a top formation which marks the end of a rising trend. The formation consists of two tops of about the same height. The sell signal is triggered when the price breaks down below the tops.
At the first top, investors are optimists. The trend is rising and things are looking good for the company. As the second top is formed, the optimism wanes. Many are disappointed when the stock does not reach above the previous top and thereby possibly does not continue the rising trend. When the price breaks down below the bottom between the two tops, the support there is broken. Optimism has been replaced with pessimism and a falling trend has begun.
A stock that has triggered a sell signal from a double top formation is indicated to continue falling, for at least as long as the formation is high.
False sell signals are triggered fairly often from double top formations. This is especially the case when it is a small formation, when the stock is still in a rising trend channel and when volume development is positive. At a sell signal from a double top formation the stock as a whole should be assessed, not solely the sell signal. Many investors have sold long term winners too soon following weak signals from double top formations. The following applies:
Stocks with these negative signal have on average outperformed the market in the following months. Annualised return has been 1.8 percentage points (pp) better than benchmark.
Annualised return (based on 66-day figures) | |
Negative signal medium term | 13.4% |
Reference index | 11.6% |
Excess return | 1.8pp |
The research results are based on 2987 signals from Nordic stocks in the period 2008-2020.
