A lower price-to-book ratio generally means that a stock is less expensive. This may be because the market has undervalued the company’s net asset value or future growth potential. Conversely, a higher price-to-book ratio generally means that a stock is more expensive. This may be because the market has overvalued the company’s net asset value or future growth potential.
