Disliked... I sometimes wonder if this was the same with the turtle system, it used to work for such a long time but then suddenly only gave out random signals. Maybe it had an extraordinary long lucky streak.Ignored
I think fundamental analysis is important, but not in a classical way as being used on Wall Street or taught in business schools / CFA curricula, which attempts to link changes in fundamentals to asset prices in a linear fashion.
The key question is to asses fundamental macro situation (are we in crisis? recovering from one? goldilocks period? high inflation etc .) and then pick the correct technical system to trade while macro environment persists. When macro picture changes, one has to be able and willing to change the technical method.
