Separately, recently, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author. TheStreet Ratings has this to say about the recommendation:

We rate DELTA AIR LINES INC as a Buy with a ratings score of A+. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that we rate. The company's strengths can be seen in multiple areas, such as its increase in net income, solid stock price performance, growth in earnings per share, largely solid financial position with reasonable debt levels by most measures and good cash flow from operations. We feel its strengths outweigh the fact that the company shows low profit margins.

Highlights from the analysis by TheStreet Ratings Team goes as follows:

  • The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the Airlines industry. The net income increased by 268.3% when compared to the same quarter one year prior, rising from $357.00 million to $1,315.00 million.
  • Looking at where the stock is today compared to one year ago, we find that it is not only higher, but it has also clearly outperformed the rise in the S&P 500 over the same period. Although other factors naturally played a role, the company's strong earnings growth was key. The stock's price rise over the last year has driven it to a level which is somewhat expensive compared to the rest of its industry. We feel, however, that other strengths this company displays justify these higher price levels.
  • DELTA AIR LINES INC reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. This company has reported somewhat volatile earnings recently. But, we feel it is poised for EPS growth in the coming year. During the past fiscal year, DELTA AIR LINES INC reported lower earnings of $0.75 versus $12.29 in the prior year. This year, the market expects an improvement in earnings ($4.62 versus $0.75).
  • The debt-to-equity ratio is somewhat low, currently at 0.85, and is less than that of the industry average, implying that there has been a relatively successful effort in the management of debt levels. Even though the company has a strong debt-to-equity ratio, the quick ratio of 0.35 is very weak and demonstrates a lack of ability to pay short-term obligations.
  • Net operating cash flow has significantly increased by 52.20% to $2,067.00 million when compared to the same quarter last year. Despite an increase in cash flow of 52.20%, DELTA AIR LINES INC is still growing at a significantly lower rate than the industry average of 133.77%.
