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.

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.

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 stock to keep an eye on is TriNet (TNET Quick QuoteTNET - Free Report) . TNET is currently sporting a Zacks Rank #2 (Buy), as well as a Value grade of A. The stock holds a P/E ratio of 14.76, while its industry has an average P/E of 16.92. Over the past year, TNET's Forward P/E has been as high as 19.82 and as low as 12.04, with a median of 16.29.

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