Evaluating a company’s actual worth is a critical step in stock market investing. While share prices reflect current market sentiment, they may not always represent the intrinsic value of a business. To assess this, investors often compare two fundamental metrics: book value and market value. Book value refers to a company’s net asset value as recorded in its financial statements. In contrast, market value reflects the price investors are willing to pay for its shares in the open market.
This blog outlines the difference between market value and book value and explains how each measure contributes to understanding a company’s valuation.
What is book value?
Book value refers to the actual worth of a company based on its financial statements. It represents what the business would be worth if it sold all its assets and paid off all its liabilities. Essentially, it tells you what the company is worth on paper.
Example:
Suppose you’re thinking of investing in a small business. The company owns machinery, furniture and inventory, and has ₹50 lakh in total assets. It also owes ₹20 lakh in loans and expenses. Subtracting the liabilities from the assets (₹50 lakh – ₹20 lakh) gives you a book value of ₹30 lakh.
Now, imagine the company has 3 lakh shares. Divide the book value (₹30 lakh) by the number of shares (3 lakh), and you get a book value per share of ₹10. If the market price per share is ₹8, you might get a good deal. But if it is ₹15, you are paying more than its book value, possibly because of expected growth potential.
What is market value?
Market value is the current worth of a company as determined by the stock market. It reflects the price investors are willing to pay for the company at any given moment. It is calculated by multiplying the total number of outstanding shares by the current share price.
For example, suppose you are looking at a company named ‘XYZ Ltd.’ If its share price is ₹500 and there are one crore shares in circulation, its market value would be ₹500 × 1 crore = ₹500 crore.
Importance of book value
Book value is important for the following reasons:
-
When market conditions are volatile, book value serves as a stable benchmark. Use it as a reference point to ascertain if a stock is underpriced or overpriced. It helps distinguish between market hype and the company’s financial strength.
-
Spot stocks that trade below their intrinsic worth by comparing the book value with the market price. A price-to-book (P/B) ratio below 1 may indicate undervaluation, allowing you to invest in companies with solid fundamentals at a discount.
-
Book value reflects the company’s retained earnings, asset base and liabilities. Monitoring changes in book value over time enables you to evaluate whether the company is growing its asset base responsibly and managing its debts efficiently, which is crucial for long-term investing.
-
Using book value as a reference reduces the risk of overpaying for a stock. It gives you a tangible measure of asset backing for your investment, offering a cushion in case market sentiment turns negative and share prices fall unexpectedly.
Importance of market value
Here is the relevance that market value holds in the context of investors.
-
Market value shows how the broader market perceives the company’s future potential. A rising market value indicates growing investor confidence. This perception often reflects expectations of revenue growth, profitability and innovation.
-
Market value influences whether a company is a takeover target. If you invest in a company with a low yet undervalued market cap, it might become an acquisition candidate. Mergers and acquisitions can significantly boost share prices, giving you capital appreciation benefits if you hold such stocks.
-
Companies with higher market value are eligible for inclusion in major indices such as the Nifty 50 or the Sensex. Inclusion often drives up liquidity and investor interest.
-
Companies with strong market value can raise capital more easily through equity offerings.
Difference between book value and market value
Here is a quick comparison of book value vs market value:
Definition | The value of assets minus liabilities, as recorded on the balance sheet. Represents the net asset value of a company. | The prevailing buy/sell price for an asset or security. Reflects investor sentiment and market dynamics. |
Calculation | Calculated as Total Assets-Total Liabilities. | Determined by supply and demand dynamics, affected by investor perceptions, economic conditions, and company performance. |
Accounting Basis | Based on historical cost, adjusted for depreciation, amortisation, and impairments. | Reflects the real-time trading price of assets, influenced by factors like earnings reports, news events, and market trends. |
Purpose | Used to assess the intrinsic value of a company’s assets. | Used to determine the worth of an asset or company based on current market conditions. |
Stability | Generally stable and changes gradually over time, reflecting long-term asset values. | Highly volatile, fluctuating frequently based on market sentiment and economic conditions. |
Application | Commonly used in financial analysis to evaluate investment opportunities and company performance. | Key metric for investors to make buying or selling decisions, reflecting perceived value and future potential. |
Example | If a company owns machinery purchased at ₹10,000, and after depreciation, it’s valued at ₹6,000, the book value would be ₹6,000. | If a company’s stock is trading at ₹150 per share on the stock exchange, that’s the current market value per share. |
Conclusion
Understanding book value vs market value helps you make smarter, more informed investment decisions. Book value reveals a company’s tangible financial standing, while market value shows how the public perceives its future potential. These metrics help you evaluate whether a stock is a true bargain or just riding a wave of market sentiment.
