Investtech Research: Excess return from stocks in rising trends

Published 14 February 2020

"Trend" is a key concept in technical analysis. Technical analysis theory states that stocks in rising trends will continue to rise within the trend, and new research results from Investtech largely confirm this theory. 

Trends are one of the most important elements of technical analysis. They are visual and intuitive and describe in which direction a stock is moving. A rising trend indicates lasting and increasing optimism among investors, often as a result of a great deal of positive news about the stock.

Identifying a trend requires studying the price movements. Stock prices rarely move in a straight line. Instead they move in a series of tops and bottoms. Drawing a straight line through two or more rising bottoms produces the support line in a rising trend. Continue to draw a line parallel to the support line through the rising tops. This line is called the trend’s resistance line. Support and resistance lines combined make up the trend. The trend gives the rate of increase for the stock price, and extrapolating trend lines gives the price target for the stock. There are gradual transitions between rising trends, horizontal trends and falling trends.

Investtech’s algorithms identify trends for you. We have developed automatic algorithms for trend identification that find the "best" trend in the chart every day, taking into account trend density, number of data points near floor and ceiling, etc. In a medium term Investtech chart with 18 months' price history some 80,000 different trend alternatives are assessed every day. These are assigned a score and the trend with the highest score is selected. A current example may be Apple, which is in a rising trend in the short, medium and long term per 12 February.

Our subscribers can find stocks with these positive signals using for instance the tool Top50.

We wanted to study the statistical results yielded by buy signals from rising trends and therefore studied return from Norwegian, Swedish, Danish and Finnish stocks following buy and sell signals from rising and falling trends identified in Investtech’s price charts in the short, medium and long term. We had up to 23 years of data, from 1996 to 2018. We defined a buy signed as the first day a stock entered a rising trend, or when the stock was in a rising trend and it had been more than 22 days since the previous signal.

The chart below shows average price development following buy signals from rising trends identified in Investtech’s medium term price charts in the Nordic markets. The signals are triggered on day 0. Only days when the exchange is open are included, so 66 days equal approximately three months. The thick blue line shows the development of buy signal stocks. The shaded areas are the standard deviation of the calculations. The thin blue line shows benchmark development in the same period as the buy signal stocks.

Stocks in short term rising trends rose an average of 1.8 per cent in one month. Compared to benchmark in the same period, the stocks in rising trends did 0.8 percentage points better, which equals an annualised excess return of 10.1 percentage points.

Stocks in medium term rising trend rose an average of 4.9 per cent in three months. Compared to benchmark in the same period, stocks in rising trends did 1.8 percentage points better, which equals an annualised excess return of 7.5 percentage points.

Stocks in long term rising trends rose an average of 4.0 per cent in three months. Compared to benchmark in the same period, stocks in rising trends did 1.3 percentage points better, which equals an annualised return of 5.2 percentage points.

The time period for the study is fairly long, the quality of the data is considered to be good and the algorithms used are entirely automatic. Statistical measures suggest a high degree of significance. The results are similar across the four markets and signal strength variation over time has been small. This indicates that we have identified real effects in the markets, which persist over time.

There is high likelihood that trend signals will give good indications of how stocks will develop also in the future. Stocks in rising trends are expected to outperform benchmark.
