Book-to-Market Ratio

A ratio of a publicly-traded company's book value to its market value. That is, the BTM is a comparison of a company's net asset value per share to its share price. This is a useful tool to help determine how the market prices a company relative to its actual worth. A ratio greater than one indicates an undervalued company, while a ratio less than one means a company is overvalued. Value managers seek out companies with high BTMs for their portfolios.

Fama and French (1992)--hereafter F&F--and Jegadeesh and Titman (1993) convincingly summarized the evidence that "diversifiable" individual characteristics, like book-to-market, size and momentum, could capture important cross-sectional variation in average stock returns.
