摘要

本研究探讨了COVID-19对印度部门市场波动结构的影响。ARMA(p,q)- GJR-GARCH(1,1)-std模型用于确定从2020年1月至2021年12月期间13个选定行业的每日条件波动率。采用分位数回归模型检查大流行期间每个部门波动结构的变化。研究结果表明，金属、油气和电力行业的波动对市场波动更为敏感，新增病例数量超过阈值，市场波动未产生极端溢出效应。此外，在新冠肺炎病例增加期间，银行、金属、油气、私人银行和电力行业的波动对新闻情绪的反应更为敏感。此外，研究结果还表明，新闻情绪有助于控制行业市场的显著波动。

Demystifying the Impact of COVID-19 on Structural Volatility of Indian Sectoral Market: A Quantile Regression Analysis

The present study explores the impact of COVID-19 on the volatility structure of the sectoral market in India. ARMA(p,q)- GJR-GARCH(1, 1)-std model is used to determine the daily conditional volatility for 13 selected sectors over the period starting from January 2020 to December 2021. The quantile regression model is employed to examine the changes in the structure of volatility in each sector over the pandemic duration. The results of the study show that the volatility of Metal, Oil–Gas and PSU are more sensitive to market volatility, whereas the volume of new COVID-19 cases exceeds the threshold limit, and no extreme spillover is observed from the market volatility. In addition to this, Bankex, Metal, Oil–Gas, Private Banks and Power sector volatility are more responsive to news sentiments during the period of increase in new COVID-19 cases. Furthermore, the results also reveal that news sentiments help to control the significant fluctuation in the sectoral market.
