Valuation is described as a craft, not a science or art, requiring continuous learning and improvement. The author focuses on the equity risk premium (ERP), questioning standard practices. Traditional historical ERP estimation, primarily US-based, is criticized for being backward-looking and potentially biased. A forward-looking approach, using current stock prices and expected cash flows to derive implied ERP, is proposed as a superior alternative. This implies the ERP in the market. The author monitors the implied ERP, especially during market crises, highlighting its sensitivity to market sentiment. Key lessons learned include the dynamic nature of the ERP, its role as a market pricing indicator, and its significance in financial analysis. The author adapted practices by calculating and publishing monthly ERP estimates. There's a comprehensive paper about ERP that explores determinants, historical methods, and forward looking ones. It is now made available for public use. The paper emphasizes the volatile nature of the ERP, influenced by various market factors.
