Book Value vs Market Value of Shares

Before investing in shares, everyone is concerned about the valuation of shares, whether they are fairly valued or not, while a few investors focus only on the current market price of the share. Both book value and market value plays an important role in making informed decisions.

In today’s blog post, we will give you an overview of the book value and market value of shares, along with their key differences.

What is the Book Value of Shares?

Book value of a share refers to the net asset value of the company, which is derived after adjusting its liabilities, and it is divided by the total number of outstanding shares. It reflects the value of each share unit, which is calculated based on the company’s financials.

Features of the Book Value of Shares

The key features of the book value of the shares are as follows:

  1. Financial Data: The book value of shares is calculated based on the company’s financial information, including assets and liabilities.
  2. Net Worth: It reflects the net worth of the company, which is derived after adjusting for all its liabilities.
  3. Higher the Better: The higher the book value of the company, the better the investment opportunity.
  4. Fundamental Investing: The book value of the company is generally used by the investor for picking right stocks.

Importance of the Book Value of Shares

The key importance of the book value of shares is as follows:

  1. Actual Valuation: The book value helps in the identification of the actual value of shares based on the financial statements, which helps an investor in identifying whether the shares are fairly valued or not.
  2. Fundamental Analysis: It helps in analysing a company based on the fundamentals to find out its actual value.
  3. Reduces Risk: Investing in stocks which are trading in a range around its book value is considered a safe bet by investors.
  4. Strength: If the book value of the companies is increasing over a period, it reflects the effective management and strong financials and growth in the company.

Formula to Calculate the Book Value of Shares

The formula to calculate the book value of a share is as follows:

Book Value of Share = (Total Assets – Total Liabilities – Preference Share Capital) / Total Number of Equity Shares Outstanding

Example of Book Value

Suppose a company named ABC Limited has a total asset of INR 12 crore, liabilities of 7 crore, and preference share capital of 1 crore and 8 lakh of equity shares.

Let’s calculate the book value of ABC Limited. 

By applying the formula 

Book Value per share = Total Assets – Total Liabilities – Preference Share Capital / Total Outstanding Equity Share

= (12cr. – 7cr. – 1cr.) / 8lakhs 

= 4cr. / 8lakhs

= 50 INR

Hence, the book value per share is 50 INR.
