Separately, TheStreet Ratings Team has a "Buy" rating with a score of B on Delta stock.
The company's strengths can be seen in multiple areas, such as its growth in earnings per share, increase in net income, good cash flow from operations, largely solid financial position with reasonable debt levels by most measures and notable return on equity.
The team believes its strengths outweigh the fact that the company has had lackluster performance in the stock itself.
