Here at Zacks, we focus on our proven ranking system, which places an emphasis on earnings estimates and estimate revisions, to find winning stocks. But we also understand that investors develop their own strategies, so we are constantly looking at the latest trends in value, growth, and momentum to find strong companies for our readers.

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 tried-and-true metrics and fundamental analysis to find companies that they believe are undervalued at their current share price levels.

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 value investors might notice is Assurant (AIZ). AIZ is currently sporting a Zacks Rank of #2 (Buy), as well as an A grade for Value.

Another valuation metric that we should highlight is AIZ's P/B ratio of 2.10. 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 solid versus its industry's average P/B of 2.31. Over the past year, AIZ's P/B has been as high as 2.25 and as low as 1.68, with a median of 1.90.

Value investors also frequently use the P/S ratio. This metric is found by dividing a stock's price with the company's revenue. This is a popular metric because sales are harder to manipulate on an income statement, so they are often considered a better performance indicator. AIZ has a P/S ratio of 0.92. This compares to its industry's average P/S of 0.98.

Finally, investors will want to recognize that AIZ has a P/CF ratio of 11.70. 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 12.22. Over the past 52 weeks, AIZ's P/CF has been as high as 12.55 and as low as 8.50, with a median of 10.44.

These are only a few of the key metrics included in Assurant'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, AIZ looks like an impressive value stock at the moment.
