Explanation

There are two components of the P/B ratio formula.

  • The first component is the market price per share. Market price per share is volatile, and it continually changes. The investor can decide to take the market price for a definite period and use an averaging method to find a median.
  • The second component of this ratio is the book value per share. There are many ways we can calculate the book value of the company. The best and most common way to find out the company’s book value is to deduct the total liabilities from the total assets. Doing this allows investors to find out the actual value at a certain time. Alternatively, the investors can also look at shareholders’ equity to determine the book value.

As you can understand, this ratio tries to analyze the proportion of the market price of each equity share and the book value per shareBook Value Per ShareThe book value per share (BVPS) formula evaluates the actual value of the common equity for each outstanding share, excluding the preferred stock value.
