# Price Index 1Y ex LM

Stocks that showed the highest increase during the last 12 months continue to move upwards in the following months. At the same time, stocks that showed the highest increase during a month tend to be part of the losers during the next month. This factor improves the predictive power of the Price Index 1Y by ignoring the final month.
