I sometimes suspect that these analysts whack the stock just to give them an entry point since the stock always reacts quite badly to downgrades. I'd love to get a look at Global Hunter's trading records, not to mention the Goldman Sacks records from years ago when they did the same thing a couple of times.
Please note that these analyst downgrades have happened many times in the past, accompanied by big price drops. Often Goldman Saks was involved. The price stays low for a week or two and then comes roaring back. If you are a bull on this stock this could be a buying opportunity ... just saying.
