DTK — Diamond Trust Bank Kenya Limited

Graham's number is √(22.5 × EPS × BVPS): a P/E ceiling of 15 times a P/B ceiling of 1.5, applied to one year's earnings and book value. The Graham number primer works through it. It is a computation, not a recommendation.

Tests: Graham's criteria, with GrowingGrass bank tests in place of financial strength.

Fiscal year

six months to 30 Jun 2026

Interim: six months to 30 Jun 2026, unaudited. Earnings use the trailing twelve months to Jun 2026, built from reported half-year and full-year figures. Every test below is flagged interim and will be replaced when the full year is published.

√(22.5 × 39.46 × 366.18) = 570.22

The Graham number for the twelve months to Jun 2026, from trailing-twelve-month EPS and BVPS at the period end. Tap a figure below for its source and date.

Discount to Graham number: +70.5% at the results-day price of 168.50. Positive means the price was below the Graham number; negative means above.
