For each group included in this publication, an array of fundamental statistical information is provided. Data presented includes: Price/Earnings Ratios, Price/Sales, Estimated Long Term Growth, and Relative Strength rankings. Individual stock performance is shown for the current month and year-to-date.  

Performance stated for Leuthold industry groups is calculated using a proprietary weighting system that is more in line with how we believe a manager might weight companies within a portfolio. This is different from S&P, which uses a straight market capitalization-weighted index for the construction of its groups. We believe our approach is superior, as it removes the hindrance of group performance being dominated by the largest component stocks.
