In this paper, we study risk from the perspective of peak-to-valley market drawdowns. The objective is to gain empirical insights into the drawdown behavior of various asset classes during several time intervals. While the existing literature on drawdown distributions has primarily focused on local drawdowns or consecutive daily drops in various asset classes, this paper focuses on extreme (cumulative) losses occurring over a daily, biweekly, monthly, quarterly and yearly period. The typical investor is mainly concerned with significant negative downward movements, especially when several of these movements happen within a specific time frame. The drawdown measure studied herein embodies this path-dependent risk better than a typical daily standard deviation or value-at-risk estimate due to its cumulative and path-dependent nature. The drawdowns over different periods are analyzed for 25 assets linked to equity indexes, commodities and foreign exchange rates. The tail observations of these drawdowns are fitted to the power law (Pareto distribution) and the stretched exponential (Weibull distribution).We find that the bulk of these observations are well fitted by both distributions. In addition, our analysis shows that the most extreme observations tend to fall between the Weibull and Pareto fits, suggesting that these can be used to define a lower and upper boundary for modeling future drawdowns.
本文从市场从峰谷回落的角度研究风险。目标是在几个时间间隔内获得对各种资产类别的缩减行为的经验见解。虽然现有的关于资产减损分布的文献主要集中在各种资产类别的局部减损或连续的每日减损上,但本文关注的是每天、每两周、每月、每季度和每年发生的极端(累积)损失。典型的投资者主要关注的是显著的负面向下运动,特别是当这些运动中的几个发生在一个特定的时间框架内。由于其累积性和路径依赖性,本文研究的缩减度量比典型的日标准差或风险值估计更好地体现了这种路径依赖性风险。研究人员分析了与股指、大宗商品和汇率相关的25种资产在不同时期的缩水情况。这些下降的尾部观测值符合幂律(帕累托分布)和拉伸指数(威布尔分布)。我们发现,大部分观测值都很好地拟合了这两种分布。此外,我们的分析表明,最极端的观测结果往往落在威布尔和帕累托拟合之间,这表明这些可以用来定义一个下限和上限,以模拟未来的下降。

Realized quantity extended conditional autoregressive value-at-risk models 实现了数量扩展条件自回归风险值模型

This paper introduces quantile models that incorporate realized variance, realized semivariance, jump variation and jump semivariation based on a conditional autoregressive quantile regression model framework for improved value-at-risk (VaR) and improved joint forecasts of VaR and expected shortfall (ES), which we denote by .VaR; ES/. Our empirical results show that high-frequency-data-based realized quantities lead to better VaR and .VaR; ES/ forecasts. We evaluate these using conditional coverage and dynamic quantile backtests for VaR, regression-based backtests for .VaR; ES/ and comparison tests based on scoring functions and model confidence sets. The study includes data sets covering the global financial crisis of 2007–9 and the Covid-19 pandemic to ensure stability over different market conditions. The results indicate that realized quantity extensions improve forecasts in terms of classic and comparison tests for all quantile levels and time periods, with stand-alone VaR forecasts benefiting the most. It is shown that the symmetric absolute value quantile model benefits the most from realized semivariance extension, whereas the asymmetric slope model benefits the most from realized variance extension.
本文基于改进的风险值(VaR)和改进的风险值与预期缺口(ES)联合预测的条件自回归分位数模型框架,引入了包含已实现方差、已实现半方差、跳跃方差和跳跃半方差的分位数模型,用。VaR表示;ES /。实证结果表明,基于高频数据的实现量导致更好的VaR和。VaR;ES /预测。我们使用VaR的条件覆盖和动态分位数回测,VaR的回归回测;ES/和基于评分函数和模型置信集的比较测试。该研究包括涵盖2007 - 2009年全球金融危机和2019冠状病毒病大流行的数据集,以确保在不同市场条件下的稳定性。结果表明,在所有分位数水平和时间段的经典检验和比较检验中,已实现的数量扩展改善了预测,其中独立VaR预测受益最大。结果表明,对称绝对值分位数模型从实现的半方差扩展中获益最大,而非对称斜率模型从实现的方差扩展中获益最大。

Considering the dual risks of extreme downside liquidity and extreme negative sentiment, we introduce the concept of the joint lower-tail risk of liquidity and investor sentiment (LISR) and construct measures to study the issue of lower-tail risk premiums in the Chinese stock market. Our findings provide convincing evidence that the premiums for LISR measures are significant regardless of the sentiment at the market or firm level. Downside liquidity risk and extreme negative sentiment cannot explain the LISR premiums separately, which means that an extreme downside change in liquidity and extreme negative sentiment have a joint effect on future stock returns. In addition, LISR premiums are robust to various portfolio double sorts, hold for various asset pricing factor models and remain significant when controlling for an extensive list of firm characteristics. Our conclusions have obvious value for improving and enriching the theoretical research on investor sentiment and liquidity risk premiums, and they provide a valuable reference for investors aiming to construct portfolios matching their own risk preferences, and for regulators supervising the market.
考虑到流动性极端下行和投资者情绪极端负面的双重风险,我们引入流动性和投资者情绪联合低尾风险的概念,并构建测度来研究中国股票市场的低尾风险溢价问题。我们的研究结果提供了令人信服的证据,证明无论市场或公司层面的情绪如何,LISR措施的溢价都是显著的。下行流动性风险和极端负面情绪不能单独解释LISR溢价,这意味着流动性的极端下行变化和极端负面情绪对未来股票收益有共同影响。此外,LISR溢价对各种投资组合双重分类具有鲁棒性,适用于各种资产定价因子模型,并且在控制广泛的公司特征列表时仍然显着。本文的研究结论对于完善和丰富投资者情绪与流动性风险溢价的理论研究具有明显的价值,为投资者构建符合自身风险偏好的投资组合以及监管机构监管市场提供了有价值的参考。
