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 we focus on mid-caps.These are stocks of companies that have market capitalizations of between $500 million and $10 billion that rank near the top of all stocks rated by our proprietary quantitative model, which looks at more than 60 factors. The stocks must also be followed by at least one financial analyst who posts estimates on the Institutional Brokers' Estimate System. They are ordered by their potential to appreciate. 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. The Buckle ( BKE) markets casual apparel such as denim, sportswear, outerwear, accessories and footwear under the brand names Buckle and The Buckle. It has been rated a buy since May 2003 primarily due to its solid financial position and growth in revenue, net income and EPS. In the second quarter of fiscal 2008, the company's revenues rose 36.6% year over year. The company improved its EPS from 38 cents per share to 78 cents per share over the same period. Net income also increased by 88.9%, rising from $11.79 million in the second quarter of fiscal 2007 to $22.28 million in the most recent quarter. The Buckle reported a gross profit margin of 44.50%, which also increased from the same quarter one year prior. Additionally, the company is clearly able to cover its short-term cash needs as it has no debt to speak of, as indicated by a quick ratio of 2.50 and a debt-to-equity ratio of zero. Finally, on Sept. 16, the company announced that at its quarterly meeting the Board of Directors authorized a special one-time cash dividend of $3 per share, along with a 30-cent-per-share quarterly dividend. A 3-for-2 stock split was also authorized at that time.
