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.

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 rely on traditional forms of analysis on key valuation metrics to find stocks that they believe are undervalued, leaving room for profits.

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 stock to keep an eye on is Helen of Troy (HELE). HELE is currently sporting a Zacks Rank of #2 (Buy), as well as a Value grade of A.

Investors will also notice that HELE has a PEG ratio of 0.96. This popular metric is similar to the widely-known P/E ratio, with the difference being that the PEG ratio also takes into account the company's expected earnings growth rate. HELE's PEG compares to its industry's average PEG of 1.62. Within the past year, HELE's PEG has been as high as 1.65 and as low as 0.79, with a median of 1.21.

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. HELE has a P/S ratio of 0.71. This compares to its industry's average P/S of 1.01.

Finally, investors will want to recognize that HELE has a P/CF ratio of 6.96. This figure highlights a company's operating cash flow and can be used to find firms that are undervalued when considering their impressive cash outlook. This stock's P/CF looks attractive against its industry's average P/CF of 27.50. HELE's P/CF has been as high as 14.21 and as low as 5.59, with a median of 9.79, all within the past year.

Value investors will likely look at more than just these metrics, but the above data helps show that Helen of Troy is likely undervalued currently. And when considering the strength of its earnings outlook, HELE sticks out at as one of the market's strongest value stocks.
