How can it be that stocks which are on extreme down trend are top rated? Take QEP as example...

I noticed that there are many top rated stocks which actually are not performant at all.

I understand that it could be a short term mismatch between rating and performance, but there are many green rated stocks which are not increasing since years...

Just have a look at the first 10 stocks in the top rated list. 6 of them underperformed in the last 5 years.

This aspect is making me not confident at all to trust the ratings. This is also one of the reasons why I decided to not continue after the free trial. 

Could you please explain that?
