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 a variety of methods, including tried-and-true valuation metrics, to find these stocks.

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.

China Construction Bank (CICHY Quick QuoteCICHY - Free Report) is a stock many investors are watching right now. CICHY is currently sporting a Zacks Rank #2 (Buy), as well as a Value grade of A.

Value investors also use the P/S ratio. The P/S ratio is calculated as price divided by sales. This is a preferred metric because revenue can't really be manipulated, so sales are often a truer performance indicator. CICHY has a P/S ratio of 1.46. This compares to its industry's average P/S of 2.2.

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