Book to market


Book to market

The ratio of book value to market value of equity. A high ratio is often interpreted as a value stock (the market is valuing equity relatively cheaply compared to book value). This is the same as a low price-to-book value ratio. Value managers often form portfolios of securities with high book to market values.

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.
