While the proven Zacks Rank places an emphasis on earnings estimates and estimate revisions to find strong stocks, we also know that investors tend to develop their own individual strategies. With this in mind, we are always looking at value, growth, and momentum trends to discover great companies.

Of these, value investing is easily one of the most popular ways to find great stocks in any market environment. Value investors use tried-and-true metrics and fundamental analysis to find companies that they believe are undervalued at their current share price levels.

Luckily, Zacks has developed its own Style Scores system in an effort to find stocks with specific traits. Value investors will be interested in the system's "Value" category. Stocks with both "A" grades in the Value category and high Zacks Ranks are among the strongest value stocks on the market right now.

One stock to keep an eye on is Loma Negra Compania Industrial Argentina S.A. Sponsored ADR (LOMA Quick QuoteLOMA - Free Report) . LOMA is currently holding a Zacks Rank of #2 (Buy) and a Value grade of A.

We should also highlight that LOMA has a P/B ratio of 0.69. The P/B ratio is used to compare a stock's market value with its book value, which is defined as total assets minus total liabilities. This stock's P/B looks attractive against its industry's average P/B of 1.38. Over the past 12 months, LOMA's P/B has been as high as 3.03 and as low as 0.63, with a median of 1.42.

Finally, our model also underscores that LOMA has a P/CF ratio of 3.02. This metric focuses on a firm's operating cash flow and is often used to find stocks that are undervalued based on the strength of their cash outlook. LOMA's P/CF compares to its industry's average P/CF of 9.69. Over the past 52 weeks, LOMA's P/CF has been as high as 9.82 and as low as 2.77, with a median of 5.85.
