What makes someone a video game analyst?

What exactly is a video games analyst? Anyone can claim to be one but who judges whether they are qualified enough to comment? Yesterday UK retailer GAME announced record sales for the first half of the year up 52% based on the same period last year. A financial analyst stated that they believed sales have peaked at which point shares in GAME then plummeted by 14% despite the record sales. ButtonBandits.com offers an alternative opinion believing that sales will rise, attempting to prove that anyone really can be a games market analyst.
