All links on this page are past results which went into effect on date of the link.
For instance, the link "20191231" on the "Dow Jones Industrial" column if the old report which was published on December 31st, 2018.
Format of the link is YYYYMMDD. The idea is to back test the results and prove their fairness (no change in the past !).
The evolution of the buy/sell signal strength can also be seen over time.
