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.

This list, updated daily, is based on data from the close of the previous trading session. Today, we look at mid-cap stocks. 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.

In addition, the stocks must be followed by at least one financial analyst who posts estimates on the Institutional Brokers' Estimate System. The stocks are ordered by their potential to appreciate.


Today begins with real estate and money management service company Jones Lang LaSalle ( JLL - Get Report), which has had a buy rating since March 2005. The company shows impressive strengths, including a noteworthy return on equity (a sign of internal strength), impressive net operating cash flow and a pattern of EPS growth reflected in the impressive appreciation of its share price.

With positive investment measures across the board, the company's low profit margins are not a major concern.


Oil and gas transportation company Plains All American Pipeline ( PAA) has had a buy rating since March 2005. The company shows impressive strengths, including positive stock price appreciation and a largely solid financial position with reasonable debt levels by most measures.

These strengths outweigh the company's subpar net income growth.


Insurance company Assurant ( AIZ - Get Report) has secured a buy rating since February 2006. The company reported stellar EPS growth, continuing a pattern of positive EPS growth over the past two years. Assurant also boasts improved return on equity, which reflects the company's internal strength.

Assurant's stock price soared over the past 12 months, making it relatively expensive vs. its industry peers. Nonetheless, its evident strengths justify the higher price levels.


Flexing its buy rating since October 2006, Tredegar ( TG - Get Report) manufactures plastic films and aluminum extrusions. The company shows a commendable debt-to-equity ratio, stout revenue growth and reasonable debt levels by most measures.

The company's strengths outweigh its low profit margins.


Rated a buy since March 2005, Credicorp ( BAP) owns and operates several prominent banks in South America. The company's strengths can be seen in its notable return on equity, EPS growth and compelling net income growth.

Though the company may have a few minor weaknesses, they are unlikely to have a significant impact on results.


Carpenter Technology ( CRS), a manufacturer of specialty metals and engineered products, has pinned down a buy rating since March 2005. The company shows a convergence of positive investment measures, including a notable return on equity, impressive stock price appreciation and compelling EPS growth.

The company's low profit margins are unlikely to threaten its buy rating.


Cameron International ( CAM) makes oil and gas pressure-control equipment, and has garnered a buy rating since March 2005. The company shows impressive revenue growth, a pattern of EPS improvements over the past two years, and net operating cash flow growth that has dwarfed that of its industry.

Cameron's strengths outweigh its low profit margins.


Hub Group ( HUBG - Get Report) is a full-service transportation provider that offers truck brokerage and logistics services throughout North America. The company's stock has been rated a buy since March 2005. Hub's strengths include its noteworthy return on equity, revenue growth, lack of significant debt and a largely solid financial position.

These strengths outweigh the company's low profit margins.


Jack in the Box which owns and operates its eponymous burger restaurants as well as the Mexican food chain Qboda, has earned a buy rating since March 2005. Its solid stock performance, impressive record of EPS growth and relatively low debt-to-equity ratio compared to its industry peers position it to continue its strong performance.

These strengths outweigh the fact that the company shows low profit margins.


Paint manufacturer, distributor and retailer Sherwin-Williams ( SHW) has earned a buy rating since March 2005. The company's strengths include solid revenue growth, steady stock appreciation, notable net income growth and a pattern of strong EPS growth over the past 24 months.

Though no company is without minor blemishes, Sherwin-Williams' positive performance shows no signs of chipping away and is positioned for continued upward momentum.
