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.

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 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 company to watch right now is MS&AD Insurance Group (MSADY Quick QuoteMSADY - Free Report) . MSADY is currently sporting a Zacks Rank of #1 (Strong Buy), as well as a Value grade of A. The stock holds a P/E ratio of 13.57, while its industry has an average P/E of 27.07. MSADY's Forward P/E has been as high as 15.92 and as low as 10.82, with a median of 11.78, all within the past year.

Another valuation metric that we should highlight is MSADY's P/B ratio of 1.27. 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 company's current P/B looks solid when compared to its industry's average P/B of 1.54. Over the past 12 months, MSADY's P/B has been as high as 1.28 and as low as 0.70, with a median of 0.80.

Value investors also love the P/S ratio, which is calculated by simply dividing a stock's price with the company's sales. This is a prefered metric because revenue can't really be manipulated, so sales are often a truer performance indicator. MSADY has a P/S ratio of 0.76. This compares to its industry's average P/S of 1.16.

These are only a few of the key metrics included in MS&AD Insurance 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, MSADY looks like an impressive value stock at the moment.
