While the proven Zacks Rank places an emphasis on earnings estimates and estimate revisions to find strong stocks, we also know that investors tend to develop their own individual strategies. With this in mind, we are always looking at value, growth, and momentum trends to discover great companies.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.Luckily, Zacks has developed its own Style Scores system in an effort to find stocks with specific traits. Value investors will be interested in the system's "Value" category. Stocks with both "A" grades in the Value category and high Zacks Ranks are among the strongest value stocks on the market right now.One company to watch right now is Voestalpine AG (VLPNY). VLPNY is currently sporting a Zacks Rank of #1 (Strong Buy) and an A for Value.Investors should also recognize that VLPNY has a P/B ratio of 1.13. The P/B ratio pits a stock's market value against its book value, which is defined as total assets minus total liabilities. VLPNY's current P/B looks attractive when compared to its industry's average P/B of 3.36. Within the past 52 weeks, VLPNY's P/B has been as high as 1.25 and as low as 0.62, with a median of 1.02.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. VLPNY has a P/S ratio of 0.56. This compares to its industry's average P/S of 0.99.These are just a handful of the figures considered in Voestalpine AG'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 VLPNY is an impressive value stock right now.
