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 tried-and-true metrics and fundamental analysis to find companies that they believe are undervalued at their current share price levels.

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 company to watch right now is inTest (INTT Quick QuoteINTT - Free Report) . INTT is currently holding a Zacks Rank of #2 (Buy) and a Value grade of A. The stock is trading with a P/E ratio of 18.55, which compares to its industry's average of 22.60. Over the past 52 weeks, INTT's Forward P/E has been as high as 22.71 and as low as 8.14, with a median of 13.52.

Finally, we should also recognize that INTT has a P/CF ratio of 8.80. 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 20.60. Over the past 52 weeks, INTT's P/CF has been as high as 12.40 and as low as 6.66, with a median of 8.72.
