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, perhaps no stock market trend is more popular than value investing, which is a strategy that has proven to be successful in all sorts of market environments. Value investors use tried-and-true metrics and fundamental analysis to find companies that they believe are undervalued at their current share price levels.

Zacks has developed the innovative Style Scores system to highlight stocks with specific traits. For example, value investors will be interested in stocks with great grades in the "Value" category. When paired with a high Zacks Rank, "A" grades in the Value category are among the strongest value stocks on the market today.

One stock to keep an eye on is ANGLO AMER ADR (NGLOY Quick QuoteNGLOY - Free Report) . NGLOY is currently holding a Zacks Rank of #2 (Buy) and a Value grade of A. The stock holds a P/E ratio of 6.71, while its industry has an average P/E of 10.92. NGLOY's Forward P/E has been as high as 12.90 and as low as 5.69, with a median of 8.55, all within the past year.

Another notable valuation metric for NGLOY is its P/B ratio of 2.04. The P/B ratio pits a stock's market value against its book value, which is defined as total assets minus total liabilities.
