I've been a RW subscriber for about 2 months from January to March 2019.  I've noticed that while backtesting from 20-30 years to today seems to show a benefit to the program long term, the short term results of most of the strategies haven't outpaced the SP500 results lately, and in many cases fell well below the return.  When testing from Nov 1, 2018 to present, it's hard to find ANY that have shown to be superior to the SP500!  Which screeners have people found that will protect us from the inevitable market correction which will occur?

I'm not 100% certain but I believe the historical reports basically show the "surviving" companies over the time period selected, generated by the screen. However, backtesting takes into account portfolio turnover, since once stock no longer fits the criteria selected, it is "sold." Perhaps a Zacks person can jump in here if I am incorrect and explain.
