    Mathematical Foundation & Statutory Rigor

    Benjamin Graham Revised Formula (1974):

    In The Intelligent Investor, Benjamin Graham formalized: V = (EPS × (8.5 + 2g) × 4.4) / Y. Here, 8.5 represents the fair P/E of a no-growth company, while 4.4 was the benchmark yield on AAA corporate bonds in 1962.

    Dual-Market Yield Gap Calibration:

    While US models use ~4.4% risk-free bond benchmarks, emerging markets like Kenya require local calibration. With CBK 10-Yr Infrastructure Bonds yielding ~14.5%–15.5% and 30% corporation tax (KRA Finance Act 2026), discounting Kenyan cash flows with foreign rates generates catastrophic valuation errors.
