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.

Looking at the history of these trends, perhaps none is more beloved than value investing. This strategy simply looks to identify companies that are being undervalued by the broader market. Value investors use fundamental analysis and traditional valuation metrics to find stocks that they believe are being undervalued by the market at large.

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 ADT (ADT). ADT is currently sporting a Zacks Rank of #2 (Buy), as well as an A grade for Value. The stock is trading with a P/E ratio of 9.10, which compares to its industry's average of 13.56. Over the past year, ADT's Forward P/E has been as high as 10.52 and as low as 8.31, with a median of 9.31.

Another notable valuation metric for ADT is its P/B ratio of 1.79. 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. This stock's P/B looks solid versus its industry's average P/B of 4.27. Over the past year, ADT's P/B has been as high as 1.93 and as low as 1.52, with a median of 1.75.

Value investors also frequently use the P/S ratio. This metric is found by dividing a stock's price with the company's revenue. This is a prefered metric because revenue can't really be manipulated, so sales are often a truer performance indicator. ADT has a P/S ratio of 1.34. This compares to its industry's average P/S of 1.89.

Finally, we should also recognize that ADT has a P/CF ratio of 3.98. 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 11.09. Over the past 52 weeks, ADT's P/CF has been as high as 4.29 and as low as 2.51, with a median of 3.26.

These are only a few of the key metrics included in ADT'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, ADT looks like an impressive value stock at the moment.
