new bachart rating - trustfull?

Hy all

The question is, if the bachart rating is applicable on a stock like HDX ! ? I mean, what are they measuring? Mainly on stockprice moving? Well, we know, it went down, but expect , on fundamentals, it will come up again (though it went down again today)
So, are they measuring fundamentals and future developments as well! ?

I know, there is no ONE trues about things and stockmarket respectivly. The big picture contains many single indications. But I´m relativly new to stockmarket (1 year descovering - 3 month´s stockholding - HDX for one month)

I like to ask: "Is there any hidden trues, why this rating is so bad, which I don´t know? I expect/ suspect/ guess not, but what do you say"?

kind regards and much appreciation from germany, with many sleepless night´s watching australien stock´s, which are my main holdings.
