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 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 to watch right now is Kingstone Companies (KINS Quick QuoteKINS - Free Report) . KINS is currently holding a Zacks Rank #2 (Buy) and 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. KINS has a P/S ratio of 1.11. This compares to its industry's average P/S of 1.26.

Finally, investors should note that KINS has a P/CF ratio of 6.50. This metric takes into account a company's operating cash flow and can be used to find stocks that are undervalued based on their solid cash outlook. KINS's current P/CF looks attractive when compared to its industry's average P/CF of 11.33. Over the past 52 weeks, KINS's P/CF has been as high as 13.32 and as low as 5.82, with a median of 9.49.

These are only a few of the key metrics included in Kingstone Companies's strong Value grade, but they help show that the stock is likely undervalued right now. When factoring in the strength of its earnings outlook, KINS looks like an impressive value stock at the moment.
