Price-to-book ratio

As explained in Investing for Programmers

A price-to-book ratio compares a company’s market value with the book value of its equity.

The price-to-book ratio measures how much investors pay for each dollar of a company’s equity. It compares market value with net assets reported on the balance sheet, making it especially useful for capital-intensive companies. section 2.4.4

Cross-company comparison

The ratio varies substantially across sectors: NVIDIA is listed at 41.22, Apple at 45.10, Sempra at 1.63, Walmart at 9.32, and Coca-Cola at 11.72. Interpret these figures alongside business type and other valuation measures rather than treating a single ratio as a verdict. section 2.4.4
