Each business day, TheStreet.com Ratings compiles a list of the top five stocks in one of five categories -- fast-growth, all-around value, large-cap, mid-cap and small-cap -- based on data from the close of the previous trading session. Today, fast-growth stocks are in the spotlight.These are stocks of companies that are projected to increase revenue and profit by at least 12% in the coming year and rank near the top all stocks rated by our proprietary quantitative model, which looks at over 60 factors. In addition, the stocks must be followed by at least one financial analyst who posts estimates on the Institutional Brokers' Estimate System. Please note that definitions of revenue vary by industry, and this screen does not make adjustments for acquisitions, which can materially affect posted results. Likewise, earnings-per-share growth may be affected by accounting charges, share repurchases and other one-time items. Note that no provision is made for off-balance-sheet assets such as unrealized appreciation/depreciation of investments, market value of real estate or contingent liabilities that might affect book value. This could be material for some companies with large underfunded pension plans. ManTech International ( MANT) provides technologies and solutions for mission-critical national security programs for the intelligence community, the space community, and various departments and agencies of the U.S. federal government. ManTech has been rated a buy since March 2005. Our rating is based on strengths such as the company's robust revenue growth, largely solid financial position, and record of EPS growth. For the second quarter of fiscal 2008, revenue rose by 33.3% year over year. This increase was primarily the result of a business strategy focused on high-end defense and intelligence markets supporting U.S. national security. Revenue growth appears to have helped boost earnings per share, which improved 40.9% when compared to the same quarter a year ago. The EPS increase from 44 cents to 62 cents represents the continuation of a pattern of positive EPS growth demonstrated by ManTech over the past two years, a trend which we feel should continue. Net income also increased in the second quarter, rising 45.0% from $15.10 million in the second quarter of fiscal 2007 to $21.90 million in the most recent quarter. ManTech's low debt-to-equity ratio of 0.16 and quick ratio of 1.30 illustrate the company's successful management of debt levels and avoid short-term cash problems.
