Unlike valuation ratios relative to the earning power such as PE Ratio, PE Ratio without NRI, PS Ratio, Price-to-Operating-Cash-Flow , or Price-to-Free-Cash-Flow, the PB Ratio measures the valuation of the stock relative to the underlying asset of the company.

Some businesses have very light assets, such as software companies or insurance agencies. The PB Ratio does not work well for these companies. Some companies even have negative equity, so the PB Ratio cannot be applied to them.
