What is CIEN's fair price?
Two classic value formulas, with today's numbers. The current price is US$379.14.
- Graham's fair price
- US$47.31
- 87.52% below the price
√(22.50 × US$4.61 × US$21.56)
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 CIEN: it paid no distributions in the last five years.
Décio Bazin only bought shares yielding at least 6% a year in distributions. The ceiling price is the average dividend per share of recent years divided by 6%.
Graham ignores growth and debt; Bazin assumes past distributions will repeat. They are reference points for comparison, not a buy recommendation.
