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 "Sell."

TheStreet Ratings rates JAVELIN Mortgage Investment as a sell. The company's weaknesses can be seen in multiple areas, such as its unimpressive growth in net income, weak operating cash flow and generally disappointing historical performance in the stock itself.

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 Real Estate Investment Trusts (REITs) industry. The net income has significantly decreased by 232.0% when compared to the same quarter one year ago, falling from -$1.86 million to -$6.19 million.
  • Net operating cash flow has significantly decreased to $0.57 million or 82.41% when compared to the same quarter last year. In addition, when comparing to the industry average, the firm's growth rate is much lower.
  • Despite any intermediate fluctuations, we have only bad news to report on this stock's performance over the last year: it has tumbled by 49.47%, worse than the S&P 500's performance. Consistent with the plunge in the stock price, the company's earnings per share are down 225.00% 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's current return on equity greatly increased when compared to its ROE from the same quarter one year prior. This is a signal of significant strength within the corporation. Compared to other companies in the Real Estate Investment Trusts (REITs) industry and the overall market, JAVELIN MORTGAGE INVESTMENT's return on equity significantly trails that of both the industry average and the S&P 500.
  • The gross profit margin for JAVELIN MORTGAGE INVESTMENT is currently very high, coming in at 88.33%. Regardless of JMI's high profit margin, it has managed to decrease from the same period last year. Despite the mixed results of the gross profit margin, JMI's net profit margin of -41.57% significantly underperformed when compared to the industry average.

Although its share price is down sharply from a year ago, do not assume that it can now be tagged as cheap and attractive. The reality is that, based on its current price in relation to its earnings, STB is still more expensive than most of the other companies in its industry.
  • STUDENT TRANSPORTATION INC's earnings per share declined by 33.3% in the most recent quarter compared to the same quarter a year ago.
