We've upgraded

Entergy

(ETR) - Get Report

from hold to buy, driven by its attractive valuation levels, considering its current price compared to earnings, book value and other measures. We feel these strengths outweigh the fact that the company has had generally poor debt management on most measures that we evaluated.

Earnings per share declined by 23.1% in the most recent quarter compared with the year-ago quarter, but we feel it is poised for EPS growth in the coming year. Revenue dropped by 2.6% since the year-ago quarter, and net income fell by 23.4%, from $313.8 million to $240.3 million.

Shares have plunged 38.8% over the past year, probably driven in part by the decline of similar magnitude in the overall market. Turning toward the future, the fact that the stock has come down in price over the past year should not necessarily be interpreted as a negative; it is one of the factors that makes this stock an attractive investment.

General Dynamics

(GD) - Get Report

from hold to buy, driven by its revenue growth, increase in net income, attractive valuation levels, notable return on equity and growth in earnings per share. We feel these strengths outweigh the fact that the company shows weak operating cash flow.

Revenue rose by 18% since the same quarter last year, and EPS increased 8.4%, though we anticipate underperformance in the coming year relative to the company's two-year pattern of positive EPS growth. Net income rose 3.1%, from $572 million to $590 million. ROE also rose, a sign of strength within the company.

We've upgraded

Kellogg

(K) - Get Report

from hold to buy, driven by its increase in net income, notable return on equity, growth in earnings per share, expanding profit margins and relatively strong performance when compared with the S&P 500 during the past year. We feel these strengths outweigh the fact that the company has had generally poor debt management on most measures that we evaluated.

Net income rose 1.9% compared with the year-ago quarter, from $315 million to $321 million. ROE also increased, a signal of strength within the corporation. EPS rose slightly, and we feel that the company's two-year trend of positive EPS growth should continue. Kellogg's gross profit margin of 44.4% is strong, though it's decreased from the same period last year. The company's 10.1% net profit margin compares favorably with the industry average. Revenue fell by 2.3% since the year-ago quarter.

We've upgraded

Occidental Petroleum

(OXY) - Get Report

from hold to buy, driven by its largely solid financial position with reasonable debt levels by most measures and expanding profit margins. We feel these strengths outweigh the fact that the company shows weak operating cash flow.

Occidental's debt-to-equity ratio of 0.1 is below the industry average, but it has a quick ratio of 0.9, which could be cause for future problems. Its gross profit margin of 44.3% is strong, though it's decreased significantly from the same period last year. The company's net profit margin of 12% compared favorably with the industry average. Revenue fell by 49% since the year-ago quarter, and EPS declined. We feel that the company is likely to report an earnings decline in the coming year. Net income fell 80.1% compared with the same quarter a year ago, from $1.8 billion to $368 million.

We've downgraded

Telefonos de Mexico

( TMX) from buy to hold. Strengths the company's notable return on equity and expanding profit margins. However, we also find weaknesses including deteriorating net income, generally poor debt management and a generally disappointing performance in the stock itself.

Telefonos de Mexico's return on equity outperforms but the diversified telecommunication services industry and the overall market. Its gross profit margin is 63.4%, though it has decreased from the same period last year. The net profit margin of 15.9% compared favorably with the industry average. Revenue fell by 27.8% since the year-ago quarter, and EPS decreased. Net income fell 36.1%, from $524.4 million to $334.9 million. The company's debt-to-equity ratio of 2.8 is above the industry average, and its quick ratio is 0.6.
