Each weekday, TheStreet.com Ratings compiles a list of the top 10 stocks in five categories -- fast-growth, all-around value, large-cap, mid-cap and small-cap -- and publishes these lists in the Ratings section of our Web site. The top 10 rankings are based on our ratings, which assess risk-adjusted returns as well as other criteria specific to the type of stock. We update the lists at the end of the business day on the basis of information available at the close of the previous trading session. Today we'll look at fast-growth stocks. These are stocks that rate in the top 10% of TheStreet.com Ratings' coverage universe and are projected to increase revenue and profit at least 12% in the coming year. In addition, the stocks must be followed by at least one financial analyst who posts earnings estimates on the Institutional Brokers Estimate System. Albemarle ( ALB), which developes, manufactures and markets specialty chemicals around the world, has been rated a buy since December 2004. The company's strengths include its robust revenue growth, good cash flow from operations, notable return on equity, solid stock price performance and largely solid financial position with reasonable debt levels by most measures. TheStreet.com Ratings feels these strengths outweigh the fact that the company has had subpar growth in net income. Precision Castparts ( PCP) manufactures metal components and products for aerospace and industrial gas turbine applications. It has been rated a buy since December 2004. The company is expected to benefit from its recent acquisitions and capacity expansion plans. This, together with higher defense spending worldwide, may allow it to repeat its recent strong financial performance.
