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.

Looking at the history of these trends, perhaps none is more beloved than value investing. This strategy simply looks to identify companies that are being undervalued by the broader market. Value investors use fundamental analysis and traditional valuation metrics to find stocks that they believe are being undervalued by the market at large.

In addition to the Zacks Rank, investors looking for stocks with specific traits can utilize our Style Scores system. Of course, value investors will be most interested in the system's "Value" category. Stocks with "A" grades for Value and high Zacks Ranks are among the best value stocks available at any given moment.

One stock to keep an eye on is China Resources Power Holdings (CRPJY). CRPJY is currently sporting a Zacks Rank of #2 (Buy), as well as an A grade for Value. The stock holds a P/E ratio of 6.45, while its industry has an average P/E of 15.45. CRPJY's Forward P/E has been as high as 7.22 and as low as 4.50, with a median of 5.40, all within the past year.

Another valuation metric that we should highlight is CRPJY's P/B ratio of 1. The P/B ratio pits a stock's market value against its book value, which is defined as total assets minus total liabilities. CRPJY's current P/B looks attractive when compared to its industry's average P/B of 2.45. CRPJY's P/B has been as high as 1.08 and as low as 0.68, with a median of 0.80, over the past year.
