What is CASN3's fair price?
Two classic value formulas, with today's numbers. The current price is R$6.02.
- Graham's fair price
- R$4.15
- 31.12% below the price
√(22.50 × R$0.33 × R$2.31)
Benjamin Graham paid no more than a P/E of 15 and a P/B of 1.5. Their product, 22.5, times earnings (EPS) and book value per share gives the fair price.
- Bazin's ceiling price
- R$0.64
- 89.37% below the price
R$0.04 (5-year average) ÷ 6%
Décio Bazin only bought stocks yielding at least 6% a year in distributions. The ceiling price is the average dividend per share of recent years over 6%.
Graham ignores growth and debt; Bazin assumes past distributions repeat. They are references to compare, not a buy recommendation.
