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 "Hold."

hold

. The company's strengths can be seen in multiple areas, such as its revenue growth, expanding profit margins and largely solid financial position with reasonable debt levels by most measures. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, weak operating cash flow and a generally disappointing performance in the stock itself.

Highlights from the ratings report include:

  • The revenue growth came in higher than the industry average of 13.6%. Since the same quarter one year prior, revenues slightly increased by 0.8%. 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 NAVIOS MARITIME PARTNERS LP is currently very high, coming in at 92.94%. It has increased from the same quarter the previous year. Along with this, the net profit margin of 19.15% is above that of the industry average.
  • NMM's debt-to-equity ratio of 0.67 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 3.75 is very high and demonstrates very strong liquidity.
  • Despite any intermediate fluctuations, we have only bad news to report on this stock's performance over the last year: it has tumbled by 46.03%, worse than the S&P 500's performance. Consistent with the plunge in the stock price, the company's earnings per share are down 45.83% 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.
  • 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 Marine industry. The net income has significantly decreased by 40.7% when compared to the same quarter one year ago, falling from $18.36 million to $10.88 million.

. The company's strengths can be seen in multiple areas, such as its notable return on equity and expanding profit margins. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, a generally disappointing performance in the stock itself and feeble growth in the company's earnings per share.

Highlights from the ratings report include:

  • The return on equity has improved slightly when compared to the same quarter one year prior. This can be construed as a modest strength in the organization. Compared to other companies in the Commercial Banks industry and the overall market, CORPBANCA's return on equity exceeds that of both the industry average and the S&P 500.
  • 49.90% is the gross profit margin for CORPBANCA which we consider to be strong. Regardless of BCA's high profit margin, it has managed to decrease from the same period last year. Despite the mixed results of the gross profit margin, BCA's net profit margin of 10.88% is significantly lower than the industry average.
  • Reflecting the weaknesses we have cited, including the decline in the company's earnings per share, BCA has underperformed the S&P 500 Index, declining 16.18% from its price level of one year ago. The fact that the stock is now selling for less than others in its industry in relation to its current earnings is not reason enough to justify a buy rating at this time.
  • The company, on the basis of change in net income from the same quarter one year ago, has underperformed when compared to that of the S&P 500 and greatly underperformed compared to the Commercial Banks industry average. The net income has decreased by 13.3% when compared to the same quarter one year ago, dropping from $73.03 million to $63.34 million.

. The company's strengths can be seen in multiple areas, such as its largely solid financial position with reasonable debt levels by most measures, expanding profit margins and notable return on equity. However, as a counter to these strengths, we also find weaknesses including feeble growth in the company's earnings per share, deteriorating net income and weak operating cash flow.

Highlights from the ratings report include:

  • TNH has no debt to speak of therefore resulting in a debt-to-equity ratio of zero, which we consider to be a relatively favorable sign. To add to this, TNH has a quick ratio of 1.61, which demonstrates the ability of the company to cover short-term liquidity needs.
  • The gross profit margin for TERRA NITROGEN CO -LP is rather high; currently it is at 55.53%. Regardless of TNH's high profit margin, it has managed to decrease from the same period last year. Despite the mixed results of the gross profit margin, TNH's net profit margin of 46.60% significantly outperformed against the industry.
  • TNH, with its decline in revenue, underperformed when compared the industry average of 11.5%. Since the same quarter one year prior, revenues fell by 28.8%. Weakness in the company's revenue seems to have hurt the bottom line, decreasing earnings per share.
  • 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 Chemicals industry. The net income has significantly decreased by 42.7% when compared to the same quarter one year ago, falling from $102.90 million to $59.00 million.
  • Net operating cash flow has decreased to $70.90 million or 36.97% when compared to the same quarter last year. In addition, when comparing the cash generation rate to the industry average, the firm's growth is significantly lower.
