Rainer...with respect....your perspective is technically right, but it is a naive portrayal.
As Fj states, reducing or eliminating positive sentiment is the gambit of shorters coupled with inciting negative sentiment.....depending on how desparate or natsty they want to be.
In my mind, I'm not in favor of someone publically and fiscally downgrading a company just to make a buck....it is the antithesis of investing in the stock market and should be illegal. It may be the way it is....but that does not make it right.
