We rate ADVANCED MICRO DEVICES (AMD) 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 company's weaknesses can be seen in multiple areas, such as its deteriorating net income, poor profit margins, weak operating cash flow, generally disappointing historical performance in the stock itself and feeble growth in its earnings per share.
