The F-Value, developed by Stanford accounting professor Joseph Piotroski, measures a company's financial strength based on nine distinct criteria. Piotroski suggest using the value as part of a value investing strategy to rank stocks with a low price-to-book ratio. The approach is described in detail in Piotroski's 2002 Paper Value Investing: The Use of Historical Financial Statement Information to Separate Winners From Losers.
