The proven Zacks Rank system focuses on earnings estimates and estimate revisions to find winning stocks. Nevertheless, we know that our readers all have their own perspectives, so we are always looking at the latest trends in value, growth, and momentum to find strong picks.

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 rely on traditional forms of analysis on key valuation metrics to find stocks that they believe are undervalued, leaving room for profits.

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 company to watch right now is SunCoke Energy (SXC Quick QuoteSXC - Free Report) . SXC is currently sporting a Zacks Rank #2 (Buy) and an A for Value.

Another valuation metric that we should highlight is SXC's P/B ratio of 0.95. Investors use the P/B ratio to look at a stock's market value versus its book value, which is defined as total assets minus total liabilities. This stock's P/B looks solid versus its industry's average P/B of 1.56. SXC's P/B has been as high as 1.55 and as low as 0.87, with a median of 1.06, over the past year.

Value investors also frequently use the P/S ratio. This metric is found by dividing a stock's price with the company's revenue. Some people prefer this metric because sales are harder to manipulate on an income statement. This means it could be a truer performance indicator. SXC has a P/S ratio of 0.51. This compares to its industry's average P/S of 0.95.

Finally, our model also underscores that SXC has a P/CF ratio of 3.61. This figure highlights a company's operating cash flow and can be used to find firms that are undervalued when considering their impressive cash outlook. This company's current P/CF looks solid when compared to its industry's average P/CF of 9.36. Within the past 12 months, SXC's P/CF has been as high as 5.13 and as low as 3.20, with a median of 3.70.

These are only a few of the key metrics included in SunCoke Energy's strong Value grade, but they help show that the stock is likely undervalued right now. When factoring in the strength of its earnings outlook, SXC looks like an impressive value stock at the moment.
