Whystock Valuation Model
Whystock fair value is estimated using a trailing P/E model adjusted for return on equity: Fair P/E = 18 + (ROE × 20). Fair Value = (Current Price ÷ Trailing P/E) × Fair P/E. A base P/E of 18 represents a typical market multiple, scaled upward for companies that earn high returns on equity. The result is a theoretical "normalised" price — not a price target or investment advice. Large deviations are common for high-growth or loss-making companies.
