英文摘要:
Value-at-Risk and its conditional allegory, which takes into account the available information about the economic environment, form the centrepiece of the Basel framework for the evaluation of market risk in the banking sector. In this paper, a new nonparametric framework for estimating this conditional Value-at-Risk is presented. A nonparametric approach is particularly pertinent as the traditionally used parametric distributions have been shown to be insufficiently robust and flexible in most of the equity-return data sets observed in practice. The method extracts the quantile of the conditional distribution of interest, whose estimation is based on a novel estimator of the density of the copula describing the dynamic dependence observed in the series of returns. Real-world back-testing analyses demonstrate the potential of the approach, whose performance may be superior to its industry counterparts.

中文摘要:
《巴塞尔银行业市场风险评估框架》的核心是风险价值及其有条件的寓言,其中考虑了有关经济环境的现有信息。本文提出了一种新的非参数框架来估计这种条件风险值。非参数方法尤其重要,因为在实践中观察到的大多数股票收益率数据集中,传统使用的参数分布不够稳健和灵活。该方法提取感兴趣的条件分布的分位数,其估计基于描述收益序列中观察到的动态相关性的copula密度的新估计量。真实世界的回测分析证明了该方法的潜力,其性能可能优于业界同行。
