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 this Web site.

Today we look at all-around value stocks. These are stocks of companies that meet a number of criteria including annual revenue of more than $500 million, lower-than-average valuations such as a price-to-sales ratio of less than 2, and leverage that is less than 49% of total capital.

In addition, they must rank near the top of all stocks rated by our proprietary quantitative model, which looks at more than 62 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, under-funded pension plans.

First up is

Volvo

( VOLV), which sold its car business to Ford in 1999 but still makes trucks, buses, construction equipment and aircraft engine parts. It has been rated a buy since March 2005.

The company has shown stellar revenue growth, solid stock price performance, outstanding earnings-per-share (EPS) growth and compelling growth in net income. These strengths outweigh the company's low profit margins.

CSX

(CSX) - Get Report

has been rated a buy since March 2005 and is the owner of one of the largest rail networks in the U.S. It has displayed strong revenue growth, impressive EPS increases and significantly improved net operating cash flow.

These strengths outweigh the company's low profit margins.

Insurance and financial services company

MetLife

(MET) - Get Report

has merited a buy rating since March 2005. With a strong market position and favorable industry trends, the company is positioned for continued strong financial performance.

MetLife has bolstered its market position in the core insurance and annuity business with its acquisition of Travelers Insurance Company and the completion of a distribution agreement with

Citigroup

(C) - Get Report

in 2005, giving it one of the broadest distribution networks in the sector.

Possible risks to the buy rating include any sharp fluctuation in equity markets, decline in investment spreads, negative competitive effects on premium rates, adverse regulatory developments or any unexpected catastrophic event.

Rated a buy since October 2005, aerospace and defense contractor

Honeywell International

(HON) - Get Report

shows a range of positive investment measures. The company has displayed an impressive record of EPS growth, good net operating cash flow and reasonable valuation levels.

Honeywell's strengths outweigh its low profit margins.

Rated a buy since March 2005,

Nucor

(NUE) - Get Report

manufactures steel products, with facilities in 13 states. It produces carbon and alloy-steel building materials and also is a recycler. The company has a very low debt-to-equity ratio (a sign of successful management of debt levels), improved return on equity and net operating cash flow growth.

These strengths outweigh the company's low profit margins.

Sempra Energy

(SRE) - Get Report

provides natural gas service throughout southern California and portions of central California. It has been rated a buy since March 2005. The company's strengths include its solid stock price performance, dramatic increases in net operating cash flow and a debt-to-equity ratio lower than that of the industry average.

With strengths such as these, the company's subpar net income growth is no cause for concern.

Telmex-Telefonos de Mexico

( TMX) owns and operates telecommunications systems in Mexico and has been rated a buy since March 2005. Its strengths include solid stock price performance, a relatively low debt-to-equity ratio and an impressive pattern of EPS growth over the 12 months prior to March 2.

These factors outweigh the fact that the company has had subpar growth in net income.

Crude oil and natural gas explorer and producer

Marathon Oil

(MRO) - Get Report

has been rated a buy since March 2005. It has shown strong stock price appreciation and improvement on its low profit margin.

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

Oil and natural gas company

ConocoPhillips

(COP) - Get Report

has been rated a buy since March 2005. Its rating is based on the company's increased volume production, improved margins and higher operating cash flow.

Since ConocoPhillips's performance is so dependent on achieving its upstream, or exploration and production, targets, any downturn in that sector would adversely affect its results. In the coming months, OPEC production quota reductions affecting Venezuela and Libya are expected to reduce the production volume.

Rio de Janeiro energy company

Petroleo Brasileiro

(PBR) - Get Report

has had a buy rating since March 2005. The company's strengths include stellar revenue growth, a steady pattern of EPS growth, improved return on equity and impressive increases on net operating cash flow.

Though Petrobras might have a few minor weaknesses, they are unlikely to have a significant impact on results.
