Abstract: In this paper, we provide an estimation of the Value-at-Risk and Expected Shortfall that captures the effects of market microstructure noise on a latent portfolio return. It is well known that noise can cause serious problems in estimating risk. Using a deconvolution kernel estimator for the conditional probability distribution function of the unobserved portfolio return, we propose an analytical approximation for conditional Value-at-Risk (VaR) and a closed-form solution for conditional Expected Shortfall (ES). We investigate in both simulation experiments and an empirical application the performance of our proposed implementation.
