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, perhaps no stock market trend is more popular than value investing, which is a strategy that has proven to be successful in all sorts of market environments. Value investors use fundamental analysis and traditional valuation metrics to find stocks that they believe are being undervalued by the market at large.

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 value investors might notice is Andritz (ADRZY Quick QuoteADRZY - Free Report) . ADRZY is currently holding a Zacks Rank #2 (Buy) and a Value grade of A. The stock is trading with P/E ratio of 11.65 right now. For comparison, its industry sports an average P/E of 29.16. Over the past 52 weeks, ADRZY's Forward P/E has been as high as 12.56 and as low as 7.77, with a median of 10.98.

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 popular metric because sales are harder to manipulate on an income statement, so they are often considered a better performance indicator. ADRZY has a P/S ratio of 0.97. This compares to its industry's average P/S of 1.32.

These figures are just a handful of the metrics value investors tend to look at, but they help show that Andritz is likely being undervalued right now. Considering this, as well as the strength of its earnings outlook, ADRZY feels like a great value stock at the moment.
