TheStreet Ratings rates DDR as a hold. The company's strengths can be seen in multiple areas, such as its revenue growth, good cash flow from operations and largely solid financial position with reasonable debt levels by most measures. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, disappointing return on equity and poor profit margins.
