What is RMBS's fair price?
Two classic value formulas, with today's numbers. The current price is $110.20.
- Graham's fair price
- $24.83
- 77.47% below the price
√(22.50 × $2.13 × $12.88)
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
- —
- Does not apply to RMBS: it paid no distributions in the last five years.
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.
