Each weekday, TheStreet.com Ratings updates its ratings on the stocks it covers. The proprietary ratings model projects a stock's total return potential over a 12-month period, including both price appreciation and dividends. Buy, hold or sell ratings designate how the Ratings group expects these stocks to perform against a general benchmark of the equities market and interest rates. While the ratings model is quantitative, it uses both subjective and objective elements. For instance, subjective elements include expected equities market returns, future interest rates, implied industry outlook and company earnings forecasts. Objective elements include volatility of past operating revenue, financial strength and company cash flows. Cavalier Homes ( CAV), a manufactured home company, has been downgraded to sell from hold. The company has shown feeble growth in its earnings per share, deteriorating net income, disappointing return on equity, poor profit margins and weak operating cash flow. Cavalier Homes has experienced a steep decline in earnings per share in the most recent quarter in comparison with its performance from the same quarter a year ago. Earnings per share have declined over the last two years. 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. It had been rated a hold since August 2006.
