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.

Of these, value investing is easily one of the most popular ways to find great stocks in any market environment. Value investors use a variety of methods, including tried-and-true valuation metrics, to find these stocks.

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 CNFinance (CNF Quick QuoteCNF - Free Report) . CNF is currently sporting a Zacks Rank of #2 (Buy), as well as a Value grade of A. The stock holds a P/E ratio of 4.72, while its industry has an average P/E of 7.77. Over the last 12 months, CNF's Forward P/E has been as high as 24.10 and as low as 4.63, with a median of 6.50.

Value investors also love the P/S ratio, which is calculated by simply dividing a stock's price with the company's sales. Some people prefer this metric because sales are harder to manipulate on an income statement. This means it could be a truer performance indicator. CNF has a P/S ratio of 0.75. This compares to its industry's average P/S of 0.83.

These are just a handful of the figures considered in CNFinance's great Value grade. Still, they help show that the stock is likely being undervalued at the moment. Add this to the strength of its earnings outlook, and we can clearly see that CNF is an impressive value stock right now.
