We document strong and unique inflation forecastability using the relative pricing between stocks with high- and low-inflation exposures. We construct the stock-level headline- and core-focused inflation betas by taking advantage of the fact that stock returns exhibit persistent sensitivity to headline-CPI shocks during the calendar month of CPI, and to core-CPI news on CPI announcement days. Above and beyond the existing forecasting methods, our stock-based portfolios contain fresh and non-redundant predictive information, indicating active price discovery on inflation in cross-sectional stocks. The core-focused forecasting portfolio emerges as a unique and unparalleled predictor for core inflation, whose predictive power and economic significance increase dramatically during the inflation surge of 2021 and 1973. Moreover, our stock-based information is not incorporated by economists in their inflation forecasts, whose room for improvement is especially large during 2021-22. We also find stronger predictability under Fed’s QE and when the Fed is behind-the-curve in fighting inflation.
