Stock Upgrades, Downgrades From TheStreet.com Ratings

Each business day, 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.

However, our rating does not incorporate all of the factors that can alter a stock's performance.

For those reasons, we believe a rating alone can not tell the whole story, and should be part of an investors overall research.

Invesco(IVZ Quote), an investment manager, has been initiated with a buy rating. The company's strengths can be seen in several areas, such as expanding profit margins, good cash flow from operations, and growth in revenue, EPS and net income.

Third-quarter income climbed 67% to $170.6 million, or 21 cents a share, significantly exceeding the growth of the capital markets industry. Revenue climbed 22%, outpacing the industry average of 17.8%, to $720.3 million. Net operating cash flow has increased to $341.40 million or 14.37% over a year ago.

Last month Invesco moved its listing to the New York Stock Exchange from the London Stock Exchange. Although no company is perfect, there does not appear to be any significant weaknesses that are likely to detract from the generally positive outlook.
