Local Likelihood Density Estimation and Value-at-Risk

الملخص EN

This paper presents a new nonparametric method for computing the conditional Value-at-Risk, based on a local approximation of the conditional density function in a neighborhood of a predetermined extreme value for univariate and multivariate series of portfolio returns.

For illustration, the method is applied to intraday VaR estimation on portfolios of two stocks traded on the Toronto Stock Exchange.

The performance of the new VaR computation method is compared to the historical simulation, variance-covariance, and J.
