The price-to-book ratio is a valuation metric that is calculated by taking the share price of a given company and dividing it by the book value of its equity.  The book value of equity, for its part, is the value of a company’s assets understood as the difference between the book value of assets minus the book value of liabilities.

The P/B ratio can be instrumental in locating cheap stocks, or stocks that might be overlooked by the market.  If a company’s P/B ratio is less than 1, this indicates that its stock is trading for less than its book value.

Since book value precludes any notion of intangible assets, it is not a metric that can be applied to all types of companies.  It works better for companies that deal in real property/assets such as merchandise than it does for companies whose assets are essentially intellectual property rights (like in much of the tech sector).
