One of the methods independent trader Alan Clement uses to devise trading system is momentum.Clement uses price movements and volumes to find an “absolute momentum level”. He then chooses 12 stocks with the highest momentum above that level. These are ranked and rotated on a weekly basis—the stocks witnessing a slowdown are replaced by those that have newly gained momentum.
