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.

Considering these trends, value investing is clearly one of the most preferred ways to find strong stocks in any type of market. Value investors use fundamental analysis and traditional valuation metrics to find stocks that they believe are being undervalued by the market at large.

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 Vodafone Group (VOD Quick QuoteVOD - Free Report) . VOD is currently sporting a Zacks Rank #1 (Strong Buy), as well as a Value grade of A. The stock has a Forward P/E ratio of 10.24. This compares to its industry's average Forward P/E of 11.05. VOD's Forward P/E has been as high as 12.50 and as low as 8.12, with a median of 9.80, all within the past year.

We should also highlight that VOD has a P/B ratio of 0.5. The P/B ratio is used to compare a stock's market value with its book value, which is defined as total assets minus total liabilities. This company's current P/B looks solid when compared to its industry's average P/B of 1.19. Within the past 52 weeks, VOD's P/B has been as high as 0.50 and as low as 0.31, with a median of 0.38.
