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.

Of these, value investing is easily one of the most popular ways to find great stocks in any market environment. Value investors rely on traditional forms of analysis on key valuation metrics to find stocks that they believe are undervalued, leaving room for profits.

On top of the Zacks Rank, investors can also look at our innovative Style Scores system to find stocks with specific traits. For example, value investors will want to focus on the "Value" category. Stocks with high Zacks Ranks and "A" grades for Value will be some of the highest-quality value stocks on the market today.

One company to watch right now is CNO Financial Group (CNO Quick QuoteCNO - Free Report) . CNO is currently sporting a Zacks Rank of #2 (Buy) and an A for Value.

We should also highlight that CNO has a P/B ratio of 1.51. The P/B ratio pits a stock's market value against 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 2.40. Within the past 52 weeks, CNO's P/B has been as high as 1.67 and as low as 1.15, with a median of 1.36.

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 prefered metric because revenue can't really be manipulated, so sales are often a truer performance indicator. CNO has a P/S ratio of 0.89. This compares to its industry's average P/S of 1.04.

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