The proven Zacks Rank system focuses on earnings estimates and estimate revisions to find winning stocks. Nevertheless, we know that our readers all have their own perspectives, so we are always looking at the latest trends in value, growth, and momentum to find strong picks.

Of these, perhaps no stock market trend is more popular than value investing, which is a strategy that has proven to be successful in all sorts of market environments. Value investors use a variety of methods, including tried-and-true valuation metrics, to find these stocks.

Zacks has developed the innovative Style Scores system to highlight stocks with specific traits. For example, value investors will be interested in stocks with great grades in the "Value" category. When paired with a high Zacks Rank, "A" grades in the Value category are among the strongest value stocks on the market today.

One company value investors might notice is Cementos Pacasmayo (CPAC Quick QuoteCPAC - Free Report) . CPAC is currently sporting a Zacks Rank #2 (Buy), as well as a Value grade of A. The stock holds a P/E ratio of 10.03, while its industry has an average P/E of 23.97. Over the past 52 weeks, CPAC's Forward P/E has been as high as 13.10 and as low as 7.26, with a median of 8.91.

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 popular metric because sales are harder to manipulate on an income statement, so they are often considered a better performance indicator. CPAC has a P/S ratio of 1.58.
