Notes
What is Price-to-Book (P/B) Valuation?
Price-to-Book (P/B) Valuation estimates a company's Fair Value based on its Book Value and the P/B multiple applied to that Book Value.
The P/B ratio compares a company's share price with its Book Value per Share. It shows how the market values the company relative to the net assets recorded on its balance sheet.
Historical P/B ratios show the valuation multiples at which the company has traded in the past. They can be used as a reference for estimating Fair Value from the company's current Book Value per Share.
P/B Valuation is most useful for companies where Book Value is economically meaningful, such as banks, insurers and asset-heavy businesses.
How the P/B Model Works
The Price-to-Book model estimates fair value by calculating the company's historical P/B multiples, selecting a valuation P/B, and applying it to Book Value per Share.
P/B Formula
Key Model Assumptions
• Historical P/B ratios are calculated only for years with valid positive Book Value per Share.
• The 10 most recent valid historical P/B ratios are used to estimate the company's typical valuation multiple.
• The historical median P/B forms the Base valuation assumption.
• Conservative and optimistic scenarios adjust the historical median P/B.
• Historical P/B multiples may not remain representative if the company's asset base, profitability or business model changes materially.
Step 1 — Calculate Historical P/B Ratios
Historical Median P/B = 37.10x
The model calculates historical Book Value per Share and historical P/B ratios. The median of the 10 most recent valid P/B ratios is then used as Apple's historical valuation benchmark. The resulting median P/B is 37.10x.
Step 2 — Select the Valuation Multiple
The selected scenario adjusts the historical median P/B to determine the valuation multiple used to estimate Fair Value. Under the base scenario, the model uses a P/B multiple of 37.10x.
Step 3 — Estimate Fair Value per Share
The selected P/B multiple is applied to Apple's current Book Value per Share of $7.32 to estimate a Fair Value per Share of $271.63.
Step 4 — Compare With the Current Market Valuation
Current P/B shows the multiple currently assigned to Apple's Book Value. The stock currently trades at 45.58x compared with a historical median of 37.10x.
The Valuation Gap compares the estimated Fair Value with the current stock price of $333.69. Under the current assumptions, the Valuation Gap is -18.6%.
