This paper offers a novel approach to identify the relationship between extensive option panels and market returns using functional predictive regression. Employing our approach on the options and realized returns of the S&P 500, we achieve a remarkable performance in predicting S&P 500 monthly returns, yielding a 4.720% (6.198%) in-sample (out-of-sample) R2. The performance of our approach is superior to that of other well-known predictors and equilibrium models. The out-of-sample performance delivers substantial utility gains over historical averages. We find that both the use of option panels and the adoption of functional regression are indispensable for the outperformance.
