TheStreet Ratings' stock model projects a stock's total return potential over a 12-month period including both price appreciation and dividends. Our Buy, Hold or Sell ratings designate how we expect these stocks to perform against a general benchmark of the equities market and interest rates.

While plenty of high-yield opportunities exist, investors must always consider the safety of their dividend and the total return potential of their investment. It is not uncommon for a struggling company to suspend high-yielding dividends which could subsequently result in precipitous share price declines.

TheStreet Ratings' stock rating model views dividends favorably, but not so much that other factors are disregarded. Our model gauges the relationship between risk and reward in several ways, including: the pricing drawdown as compared to potential profit volatility, i.e. how much one is willing to risk in order to earn profits?; the level of acceptable volatility for highly performing stocks; the current valuation as compared to projected earnings growth; and the financial strength of the underlying company as compared to its stock's valuation as compared to its stock's performance.

These and many more derived observations are then combined, ranked, weighted, and scenario-tested to create a more complete analysis. The result is a systematic and disciplined method of selecting stocks. As always, stock ratings should not be treated as gospel — rather, use them as a starting point for your own research.

. Among the areas we feel are negative, one of the most important has been very high debt management risk by most measures.

Highlights from the ratings report include:

  • The debt-to-equity ratio of 1.14 is relatively high when compared with the industry average, suggesting a need for better debt level management. Even though the debt-to-equity ratio is weak, GLOP's quick ratio is somewhat strong at 1.23, demonstrating the ability to handle short-term liquidity needs.
  • In comparison to the other companies in the Oil, Gas & Consumable Fuels industry and the overall market, GASLOG PARTNERS LP's return on equity is significantly below that of the industry average and is below that of the S&P 500.
  • GLOP's stock share price has done very poorly compared to where it was a year ago: Despite any rallies, the net result is that it is down by 42.89%, which is also worse that the performance of the S&P 500 Index. Investors have so far failed to pay much attention to the earnings improvements the company has managed to achieve over the last quarter.
  • The gross profit margin for GASLOG PARTNERS LP is currently very high, coming in at 78.76%. Regardless of GLOP's high profit margin, it has managed to decrease from the same period last year. Despite the mixed results of the gross profit margin, GLOP's net profit margin of 39.58% significantly outperformed against the industry.
  • GASLOG PARTNERS LP reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. This year, the market expects an improvement in earnings ($2.14 versus $1.48).

. The company's weaknesses can be seen in multiple areas, such as its deteriorating net income, generally high debt management risk, disappointing return on equity, generally disappointing historical performance in the stock itself and feeble growth in its earnings per share.

Highlights from the ratings report include:

  • The company, on the basis of change in net income from the same quarter one year ago, has significantly underperformed when compared to that of the S&P 500 and the Oil, Gas & Consumable Fuels industry. The net income has significantly decreased by 334.6% when compared to the same quarter one year ago, falling from $7.34 million to -$17.23 million.
  • The debt-to-equity ratio is very high at 3.97 and currently higher than the industry average, implying increased risk associated with the management of debt levels within the company. To add to this, TOO has a quick ratio of 0.60, this demonstrates the lack of ability of the company to cover short-term liquidity needs.
  • Return on equity has greatly decreased when compared to its ROE from the same quarter one year prior. This is a signal of major weakness within the corporation. Compared to other companies in the Oil, Gas & Consumable Fuels industry and the overall market, TEEKAY OFFSHORE PARTNERS LP's return on equity significantly trails that of both the industry average and the S&P 500.
  • Despite any intermediate fluctuations, we have only bad news to report on this stock's performance over the last year: it has tumbled by 49.15%, worse than the S&P 500's performance. Consistent with the plunge in the stock price, the company's earnings per share are down 2700.00% compared to the year-earlier quarter. 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 could be one of the factors that may help make the stock attractive down the road. Right now, however, we believe that it is too soon to buy.
  • TEEKAY OFFSHORE PARTNERS LP has experienced a steep decline in earnings per share in the most recent quarter in comparison to its performance from the same quarter a year ago. The company has reported a trend of declining earnings per share over the past two years. However, the consensus estimate suggests that this trend should reverse in the coming year. During the past fiscal year, TEEKAY OFFSHORE PARTNERS LP swung to a loss, reporting -$0.22 versus $0.94 in the prior year. This year, the market expects an improvement in earnings ($1.14 versus -$0.22).

. The company's weaknesses can be seen in multiple areas, such as its feeble growth in its earnings per share, deteriorating net income, disappointing return on equity, weak operating cash flow and generally high debt management risk.

Highlights from the ratings report include:

  • ECOPETROL SA has experienced a steep decline in earnings per share in the most recent quarter in comparison to its performance from the same quarter a year ago. Earnings per share have declined over the last two years. We anticipate that this should continue in the coming year. During the past fiscal year, ECOPETROL SA reported lower earnings of $1.55 versus $3.31 in the prior year. For the next year, the market is expecting a contraction of 53.9% in earnings ($0.72 versus $1.55).
  • The company, on the basis of change in net income from the same quarter one year ago, has significantly underperformed when compared to that of the S&P 500 and the Oil, Gas & Consumable Fuels industry. The net income has significantly decreased by 96.2% when compared to the same quarter one year ago, falling from $1,672.95 million to $63.18 million.
  • Return on equity has greatly decreased when compared to its ROE from the same quarter one year prior. This is a signal of major weakness within the corporation. In comparison to the other companies in the Oil, Gas & Consumable Fuels industry and the overall market, ECOPETROL SA's return on equity is significantly below that of the industry average and is below that of the S&P 500.
  • Net operating cash flow has decreased to $1,379.89 million or 25.40% when compared to the same quarter last year. Despite a decrease in cash flow ECOPETROL SA is still fairing well by exceeding its industry average cash flow growth rate of -48.80%.
  • Despite any intermediate fluctuations, we have only bad news to report on this stock's performance over the last year: it has tumbled by 66.83%, worse than the S&P 500's performance. Consistent with the plunge in the stock price, the company's earnings per share are down 96.29% compared to the year-earlier quarter. Naturally, the overall market trend is bound to be a significant factor. However, in one sense, the stock's sharp decline last year is a positive for future investors, making it cheaper (in proportion to its earnings over the past year) than most other stocks in its industry. But due to other concerns, we feel the stock is still not a good buy right now.
