- A P/B ratio in the 1 to 3 range is typical for many established, profitable businesses. It suggests the market prices in some growth or return on equity above the cost of capital, but not excessive optimism.
- The implied book value per share is $18.00. The market is paying $2.50 for every $1.00 of net book value.
- Always compare the P/B ratio against sector peers, not the broad market. Capital-light technology firms routinely trade at 10x+ book while banks and utilities often sit near or below 1x, reflecting fundamentally different business models.
Next stepCross-check with return on equity (ROE). A high P/B is more defensible when ROE exceeds the cost of equity. If P/B is high but ROE is mediocre, the stock may be expensive relative to fundamentals.
