Stockopedia’s own data points to a jarringly simple stock market truth amidst the daily whirlwind of financial data: share prices that have gone up tend to keep going up.
It sounds almost astonishingly simple but people instinctively distrust this momentum effect - surely successful investing can’t be so easy? One of the most convincing explanations for this stock market factor is the conservatism bias - the idea that people are slow to revise their expectations when presented with new information.
That means that when the market finds a stock breaking new all-time highs or beating broker estimates it tends to undervalue this development. The rational investor can take advantage of this mispricing. Stockopedia’s Momentum Rank is a convenient way of summarising the momentum attributes of a stock - let’s use Vodafone (LON:VOD) as an example.
How to spot Momentum opportunities
The Momentum Rank is inspired by the latest research into momentum from leading academics (including Jegadeesh and Titman, George and Hwang, and Seung-Chan Park) and is based on a composite of the following Price and Estimate Momentum Factors.
Each company in the market is ranked from 1 to 100 for each of these momentum ratios and a composite score is calculated as a weighted average of all valid values. Applying this to Vodafone yields an impressive Momentum Rank of 88 - suggesting that this stock should be looked at more closely.
A high Momentum Rank should not be ignored - over the past seven years, a quarterly re-balanced portfolio of 90-100 Momentum Rank stocks has handily outperformed the FTSE All-Share (as have the 70-80 and 80-90 deciles).
Studies indicate that combining factors such as Value, Quality and Momentum is a more effective way of outperforming the market over longer time frames. That's why we have constructed our StockReports to give an instant impression of how well exposed Vodafone (LON:VOD) is to these three factors.
