We have refreshed our momentum style screen for the first time since inception on 26 July 2016. As before, the screen selects the 25 stocks exhibiting the most extreme momentum characteristics, according to our measurement method. From these we have selected 10 to focus on. Since inception the screen has underperformed both the main small-cap and micro-cap indices against a background of generally rising momentum. We have noted a subset of the basket, where decelerating momentum at the time of measurement appears correlated with significant share price falls since selection. We shall monitor this factor with the new screen, albeit there are only two such stocks showing this pattern, namely Lamprell (not rated) and Gear4music (not rated).
