It looks like Goldman Sachs has started manipulating AMD stock,as it seems they don't want it to get higher:

Goldman Sachs do something like this every time AMD's stock starts going up in value, if they are not writing articles denouncing the stock and the company while also ignoring AMD's Business road map (as if they don't know what it is) they keep down grading them while giving reasons in ignorance of that road map.
About 6 months ago the wrote a nonsense article that was full of unfounded baseless blanket statements, as is always the way with people like that, so i responded to it with hard facts and evidence. utterly cut them to ribbons, i gained countless likes and 37 followers for that article alone, and it felt great
Many have a feeling that they are very far from an independent rating agency, not just AMD, they do this to a lot of companies.
It was Goldman Sachs who predicted AMD would be in administration by about now, AMD have paid down the vast majority of their debts, they have spent the last few years paying big chunks of it off which is why they have resulted in the red since, they are now getting back into a position of being profitable, probably not in Q2, possibly in Q3. I don't have the exact figures but i know AMD's assets now outweigh their debts, AMD's last quarter results has put egg on Goldman Sachs face and it seems they are not happy about having been proven wrong.
They are, and will only continue to damage themselves as a reputable rating agency, a lot of people a raising eye brows at Goldman Sachs move here.
