The Price-to-Book (P/B) ratio is a financial metric used to compare a company's market value (price) to its book value (net asset value per share). It is determined by dividing the current market price per share of a company's stock by its book value per share. This ratio helps investors assess whether a stock is undervalued or overvalued relative to its accounting value on the balance sheet.
The formula to calculate the Price-to-Book (P/B) ratio is:
P/B Ratio = Market Price per Share/Book Value per Share
Where:
Market Price per Share is the current trading price of a company's stock. Book Value per Share is the total assets minus intangible assets and liabilities, divided by the number of outstanding shares.
A "good" P/B ratio varies by industry and depends on the nature of the business. Generally, a P/B ratio less than 15 suggests that the stock may be undervalued relative to its book value, indicating a potential buying opportunity. Conversely, a P/B ratio above 15 may indicate that the stock is overvalued. However, it's important to consider other factors like growth prospects, profitability, and market conditions alongside the P/B ratio before making investment decisions.
The main difference between the Price-to-Earnings (P/E) ratio and the Price-to-Book (P/B) ratio lies in what they measure:
