What is CTKA4's fair price?

Two classic value formulas, with today's numbers. The current price is R$33.15.

Graham's fair price
R$5.77
82.59% below the price

√(22.50 × R$0.96 × R$1.54)

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 CTKA4: 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.
