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. Beginning this week, we are publishing a daily article that takes a closer look at the ratings of the stocks on one of the lists.

Today we'll look at small-cap stocks. These are stocks with a market capitalization of less than $500 million that rate near the top of TheStreet.com Ratings' coverage universe. In addition, the stocks must be followed by at least one financial analyst who posts earnings estimates on IBES. The stocks are ranked in the order of their potential to appreciate.

Atlantic Tele-Network ( ATNI), which provides wireless and wireline telecommunications services in the Caribbean and North America, has been rated a buy since December 2004.

TheStreet.com Ratings' positive outlook on the stock is primarily influenced by the company's acquisition-led growth strategy and its focus on under-served markets. Atlantic Tele-Network's financial performance in the third quarter of its fiscal year 2006 was also encouraging.

The principal risks to our rating include termination of its exclusive right to provide wireline local and long distance telephone services in Guyana, any decline in volume of international long-distance calls, any adverse regularity developments and increasing competition.
