TheStreet Ratings rates Affymetrix as a hold. The company's strengths can be seen in multiple areas, such as its compelling growth in net income, largely solid financial position with reasonable debt levels by most measures and good cash flow from operations. However, as a counter to these strengths, we find that the stock has had a generally disappointing performance in the past year. You can view the full Affymetrix Ratings Report.
