Editor's Note: TheStreet ratings do not represent the views of TheStreet's staff or its contributors. Ratings are established by computer based on metrics for performance (which includes growth, stock performance, efficiency and valuation) and risk ( volatility and solvency). Companies with poor cash flow or high debt levels tend to earn lower ratings in our model. NEW YORK ( TheStreet ) -- CenturyLink (NYSE: CTL ) has been reiterated by TheStreet Ratings as a hold with a ratings score of C+. The company's strengths can be seen in multiple areas, such as its compelling growth in net income, reasonable valuation levels and good cash flow from operations. However, as a counter to these strengths, we also find weaknesses including a generally disappointing performance in the stock itself and generally higher debt management risk.
