Greenrock Energy Co  (ROCO:7833) PB Ratio Explanation

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.

The PB Ratio works the best for the businesses that earn most of their profit from their assets, e.g. banks and insurance companies.


Be Aware

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.
