Altrion's management was pleased with the first quarter results and stated that the company expects to fulfill the modest growth in diluted EPS that it anticipates for the full year. A somewhat disappointing result for return on equity is a concern, but we feel that the strengths detailed above outweigh this potential weakness. In addition, we feel that the stock has good upside potential despite having already risen over the past year. It goes without saying, however, that even the best stocks can fall in an overall down market. TheStreet.com Ratings, recently cited for Best Stock Selection from October 2007 through February 2009 , is an independent research provider that combines fundamental and technical analysis to offer investors tremendous value in volatile times. To see how your portfolio can use this research, click here now! Our quantitative rating, which can be viewed for any stock through our stock screener stock rating screener, is based on a variety of historical fundamental and pricing data and represents our opinion of a stock's risk-adjusted performance relative to other stocks. However, the rating does not incorporate all of the factors that can alter a stock's performance. For example, it doesn't always factor in recent corporate or industry events that could affect the stock price, nor does it include recent technology developments and competitive dynamics that may affect the company. For those reasons, we believe that a rating alone cannot tell the whole story and that it should be part of an investor's overall research.
