Evaluate how varying market share prices and book value per share shift the observed P/B ratio.
Observe justified P/B expansion as Return on Equity surpasses the cost of capital hurdle rate.
Book Value represents the cumulative historical accounting capital invested into the business. Tangible Book Value provides a conservative liquidation benchmark by stripping away unamortized goodwill and intangible assets.
A firm only deserves to trade above book value (P/B > 1.0) if its Return on Equity exceeds its Cost of Capital (r). If ROE < r, the firm destroys shareholder capital by retaining earnings, mathematically justifying a P/B discount below 1.0.
The Price-to-Book (P/B) ratio compares a company's current market share price against its accounting Book Value Per Share (BVPS). Calculated as Stock Price / BVPS, it reflects how much equity investors are willing to pay for every dollar of net asset balance sheet equity.
Tangible Book Value removes intangible assets and unamortized goodwill from total stockholders equity. For financial institutions and commercial banks, Price-to-Tangible Book Value (P/TBV) measures true liquidation solvency without relying on soft accounting assets.
Derived from the Gordon Growth dividend discount model, Justified P/B = (ROE - g) / (r - g), where ROE is the Return on Equity, r is the Cost of Equity (hurdle rate), and g is the sustainable long-term earnings growth rate. When ROE exceeds r, justified P/B is greater than 1.0.
A P/B ratio under 1.0 means the stock trades at a discount to its net assets. This may indicate a classic deep-value bargain (Ben Graham net-net), or alternatively a value trap where the market anticipates asset write-downs, sub-cost-of-capital returns, or structural bankruptcy risk.
