Book value per common share and
market value per share are two different measures used to assess the financial health and value of a company. While both metrics provide insights into a company's worth, they are calculated using different approaches and serve distinct purposes.
Book value per common share represents the net worth of a company's common equity, which is derived from its
balance sheet. It is calculated by dividing the total common equity by the number of outstanding common shares. Common equity is the residual interest in the assets of a company after deducting liabilities. In other words, it is the shareholders' claim on the company's assets.
The book value per common share reflects the historical cost of a company's assets and liabilities, as recorded in its financial statements. It includes tangible assets such as buildings, equipment, and
inventory, as well as intangible assets like patents and trademarks. Liabilities such as loans and accounts payable are subtracted from these assets to arrive at the book value.
On the other hand, market value per share represents the price at which a company's shares are currently trading in the
stock market. It is determined by the supply and demand dynamics of the market and reflects investors' expectations about the company's future performance. Market value per share is influenced by various factors such as earnings growth prospects, industry trends, competitive positioning, and
investor sentiment.
Unlike book value per common share, market value per share is forward-looking and incorporates market participants' expectations and perceptions. It can fluctuate significantly from the book value due to factors such as market
speculation, changes in industry dynamics, macroeconomic conditions, and investor sentiment. Market value per share is influenced by factors beyond a company's balance sheet and financial statements.
The disparity between book value per common share and market value per share can be attributed to several reasons. Firstly, if a company has valuable intangible assets that are not fully reflected in its book value (e.g.,
brand recognition or intellectual property), the market value per share may exceed the book value per common share. This is because investors recognize the potential future earnings generated by these intangible assets.
Secondly, market value per share can be influenced by market sentiment and investor expectations. If investors are optimistic about a company's growth prospects, they may be willing to pay a premium for its shares, leading to a market value per share that exceeds the book value per common share. Conversely, if investors have concerns about a company's future performance, the market value per share may fall below the book value per common share.
Lastly, market conditions and supply and demand dynamics in the stock market can also impact the relationship between book value per common share and market value per share. During periods of market exuberance or
irrational exuberance, market value per share may significantly deviate from the book value per common share. Conversely, during market downturns or economic crises, market value per share may fall below the book value per common share as investors discount future earnings expectations.
In summary, while book value per common share represents the net worth of a company's common equity based on historical cost, market value per share reflects the price at which its shares are currently trading in the stock market. The former is backward-looking and based on
accounting principles, while the latter is forward-looking and influenced by investor expectations and market dynamics. The disparity between these two measures can be attributed to factors such as intangible assets, investor sentiment, and market conditions.
