You'll notice there are 22 different analysts that submit ratings to market watch about EA.
21 of them suggest a Buy or Hold. 1 suggests a Sell.
You'll also notice that 1 month ago, and 3 months ago, there were more analysts with a Sell rating. Thats before analysts had subscription or sales numbers. That would suggest he is isolated in his opinion, and people arent flocking to recommend people dump the stock. Also, its important to note he lowered the rating from OVERWEIGHT to BUY, not to SELL.
This guy was trying to make waves. All he did was fool some people on an internet forum.
