Fundamental Extrapolation and Stock Returns

Abstract

We propose an economic objective-driven pooling strategy to extrapolate multiple fundamentals simultaneously. This strategy outperforms naive extrapolation strategies that use a single fundamental variable and strategies that use past prices or analyst forecasts, and performs similarly as a machine learning-based pooling strategy. We propose a model to show that fundamental extrapolation has dual price effects: a cash flow effect that pushes stock price up relative to its fundamental value and a discount rate effect that depresses stock price via increasing the expected volatility. Our empirical results suggest that the discount rate effect dominates the cash flow effect.
