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.

The following pages contain our analysis of 3 stocks with substantial yields, that ultimately, we have rated "Buy."

. The company's strengths can be seen in multiple areas, such as its expanding profit margins, good cash flow from operations and attractive valuation levels. We feel its strengths outweigh the fact that the company has had lackluster performance in the stock itself.

Highlights from the ratings report include:

  • 37.83% is the gross profit margin for SUBURBAN PROPANE PRTNRS -LP which we consider to be strong. It has increased significantly from the same period last year. Along with this, the net profit margin of 22.79% significantly outperformed against the industry average.
  • Net operating cash flow has significantly increased by 678.57% to $126.33 million when compared to the same quarter last year. In addition, SUBURBAN PROPANE PRTNRS -LP has also vastly surpassed the industry average cash flow growth rate of 25.16%.
  • SUBURBAN PROPANE PRTNRS -LP's earnings per share declined by 8.9% 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, SUBURBAN PROPANE PRTNRS -LP increased its bottom line by earning $1.55 versus $1.44 in the prior year. This year, the market expects an improvement in earnings ($2.01 versus $1.55).
  • SPH, with its decline in revenue, underperformed when compared the industry average of 20.2%. Since the same quarter one year prior, revenues fell by 31.4%. Weakness in the company's revenue seems to have hurt the bottom line, decreasing earnings per share.

. Among the primary strengths of the company is its attractive valuation levels, considering its current price compared to earnings, book value and other measures. We feel its strengths outweigh the fact that the company has had sub par growth in net income.

Highlights from the ratings report include:

  • GLP, with its decline in revenue, slightly underperformed the industry average of 38.9%. Since the same quarter one year prior, revenues fell by 41.8%. Weakness in the company's revenue seems to have hurt the bottom line, decreasing earnings per share.
  • GLOBAL 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. This company has reported somewhat volatile earnings recently. We feel it is likely to report a decline in earnings in the coming year. During the past fiscal year, GLOBAL PARTNERS LP increased its bottom line by earning $3.96 versus $1.43 in the prior year. For the next year, the market is expecting a contraction of 50.5% in earnings ($1.96 versus $3.96).
  • The gross profit margin for GLOBAL PARTNERS LP is currently extremely low, coming in at 6.43%. Regardless of GLP's low profit margin, it has managed to increase from the same period last year. Despite the mixed results of the gross profit margin, the net profit margin of 1.02% trails the industry average.
  • The share price of GLOBAL PARTNERS LP has not done very well: it is down 22.26% and has underperformed the S&P 500, in part reflecting the company's sharply declining earnings per share when compared to the year-earlier quarter. Looking ahead, although the push and pull of the overall market trend could certainly make a critical difference, we do not see any strong reason stemming from the company's fundamentals that would cause a continuation of last year's decline. In fact, the stock is now selling for less than others in its industry in relation to its current earnings.

. The company's strengths can be seen in multiple areas, such as its revenue growth, expanding profit margins, good cash flow from operations, largely solid financial position with reasonable debt levels by most measures and solid stock price performance. We feel its strengths outweigh the fact that the company is trading at a premium valuation based on our review of its current price compared to such things as earnings and book value.

Highlights from the ratings report include:

  • The revenue growth significantly trails the industry average of 36.3%. Since the same quarter one year prior, revenues slightly increased by 5.1%. This growth in revenue does not appear to have trickled down to the company's bottom line, displayed by a decline in earnings per share.
  • The gross profit margin for GRUPO AEROPORTUARIO DEL CENT is rather high; currently it is at 62.35%. It has increased from the same quarter the previous year.
  • Net operating cash flow has significantly increased by 108.38% to $33.66 million when compared to the same quarter last year. The firm also exceeded the industry average cash flow growth rate of 75.58%.
  • Compared to its closing price of one year ago, OMAB's share price has jumped by 28.03%, exceeding the performance of the broader market during that same time frame. Looking ahead, the stock's sharp rise over the last year has already helped drive it to a level which is relatively expensive compared to the rest of its industry. We feel, however, that other strengths this company displays justify these higher price levels.
  • OMAB's debt-to-equity ratio of 0.75 is somewhat low overall, but it is high when compared to the industry average, implying that the management of the debt levels should be evaluated further. Even though the debt-to-equity ratio shows mixed results, the company's quick ratio of 4.14 is very high and demonstrates very strong liquidity.
