Group 4: Differences Between Progressive and Parallel Stock Selection - The high-growth earnings portfolio employs a progressive stock selection method, first filtering stocks based on expected earnings growth and then refining the selection using changes in analyst earnings forecasts [43][46]. - In contrast, parallel stock selection methods, which use both factors simultaneously, have shown to be less effective in terms of annual returns over the backtesting period [47][49].
