Title: Estimating Expected Shortfall Using a Conditional Autoregressive Model: CARES*

Expected shortfall (ES) has recently become an increasingly popular measure

of downside risk because of its conceptual appeal and desirable properties. This ar-

ticle proposes a new conditional autoregressive model for estimating ES (CARES)

by specifying the evolution of ES over time using an autoregressive process. We

develop a tail-based least-squares method of estimating the model parameters and

establish the consistency and asymptotic normality of the resultant estimator.

Our simulation results show that the CARES model demonstrates superior nite-

sample forecasting performance compared with other existing methods. To use

examples with real data, we implement the model to evaluate the ESs of one stock

index and two individual stocks.
