TheStreet Ratings team rates STAGE STORES INC as a Hold with a ratings score of C+. TheStreet Ratings Team has this to say about their recommendation:
"We rate STAGE STORES INC (SSI) a HOLD. The primary factors that have impacted our rating are mixed -- some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. Among the primary strengths of the company is its solid financial position based on a variety of debt and liquidity measures that we have evaluated. At the same time, however, we also find weaknesses including a generally disappointing performance in the stock itself, deteriorating net income and disappointing return on equity."
