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.

Considering these trends, value investing is clearly one of the most preferred ways to find strong stocks in any type of 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.

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 company to watch right now is Nomura (NMR Quick QuoteNMR - Free Report) . NMR is currently sporting a Zacks Rank #2 (Buy), as well as a Value grade of A. The stock is trading with a P/E ratio of 9.7, which compares to its industry's average of 13.01. Over the past 52 weeks, NMR's Forward P/E has been as high as 11.13 and as low as 6.19, with a median of 8.63.

We should also highlight that NMR has a P/B ratio of 0.89. The P/B is a method of comparing a stock's market value to its book value, which is defined as total assets minus total liabilities. NMR's current P/B looks attractive when compared to its industry's average P/B of 2.34. Over the past 12 months, NMR's P/B has been as high as 0.90 and as low as 0.62, with a median of 0.77.

Value investors also use the P/S ratio. The P/S ratio is calculated as price divided by 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. NMR has a P/S ratio of 0.72. This compares to its industry's average P/S of 2.15.

Finally, our model also underscores that NMR has a P/CF ratio of 7.63. This metric takes into account a company's operating cash flow and can be used to find stocks that are undervalued based on their solid cash outlook. This company's current P/CF looks solid when compared to its industry's average P/CF of 16.57. Over the past 52 weeks, NMR's P/CF has been as high as 9.60 and as low as 5.73, with a median of 7.23.

These are just a handful of the figures considered in Nomura'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 NMR is an impressive value stock right now.
