Here at Zacks, our focus is on the proven Zacks Rank system, which emphasizes earnings estimates and estimate revisions to find great stocks. Nevertheless, we are always paying attention to the latest value, growth, and momentum trends to underscore strong picks.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.On top of the Zacks Rank, investors can also look at our innovative Style Scores system to find stocks with specific traits. For example, value investors will want to focus on the "Value" category. Stocks with high Zacks Ranks and "A" grades for Value will be some of the highest-quality value stocks on the market today.One company value investors might notice is Avnet (AVT). AVT is currently sporting a Zacks Rank of #2 (Buy), as well as a Value grade of A.We should also highlight that AVT has a P/B ratio of 0.99. Investors use the P/B ratio to look at a stock's market value versus its book value, which is defined as total assets minus total liabilities. AVT's current P/B looks attractive when compared to its industry's average P/B of 1.40. Over the past 12 months, AVT's P/B has been as high as 1.13 and as low as 0.65, with a median of 0.94.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. AVT has a P/S ratio of 0.21. This compares to its industry's average P/S of 0.31.Finally, our model also underscores that AVT has a P/CF ratio of 10.46. This metric focuses on a firm's operating cash flow and is often used to find stocks that are undervalued based on the strength of their cash outlook. This stock's P/CF looks attractive against its industry's average P/CF of 10.90. AVT's P/CF has been as high as 14.24 and as low as 6.97, with a median of 11.15, all within the past year.These are only a few of the key metrics included in Avnet'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, AVT looks like an impressive value stock at the moment. More Stock News: This Is Bigger than the iPhone!
