TheStreet Ratings team rates GLU MOBILE INC as a Sell with a ratings score of D. TheStreet Ratings Team has this to say about their recommendation:
"We rate GLU MOBILE INC (GLUU) a SELL. This is driven by a number of negative factors, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The area that we feel has been the company's primary weakness has been its disappointing return on equity."
