Top Five Small-Cap Stocks

AAON and Atlantic Tele-Network lead the list.

Each weekday, Ratings compiles a list of the top five 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, small-cap stocks are in the spotlight. These are stocks of companies that have market capitalizations of between $50 million and $500 million 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.


(AAON) - Get AAON, Inc. Report

, a manufacturer of air-conditioning and heating equipment, has been rated a buy since June 2005. AAON's strengths can be seen in multiple areas, such as revenue growth, a largely solid financial position with reasonable debt levels by most measures, an impressive record of EPS growth over the past two years, good cash flow from operations and solid stock price performance.

Low profit margins present the main risk to the buy rating.

Telecom services provider

Atlantic Tele-Network

(ATNI) - Get ATN International, Inc. Report

has been rated a buy since May 2005. It demonstrates strong revenue growth and offers a good dividend yield at the stock's current price level. In order to strengthen its wireless business, the company has accelerated its spending to expand geographically and has also increased promotional efforts to enhance brand awareness. Atlantic operates in under-served, rural markets in the U.S., Bermuda and Guyana, all of which provide ample opportunities for growth.

The principal risks include termination of the company's exclusive right to provide wireline local and long-distance telephone services in Guyana as well as any adverse regulatory developments or economic conditions. Also, intensifying competition poses a significant threat to Atlantic Tele-Network's future prospects.

Rated a buy since December 2005,
