摘要

新冠肺炎疫情爆发,导致全球股市市值大幅下跌。本文的目的是回答以下问题:在COVID-19大流行期间,合规公司的表现是否优于不合规公司?遵守规定的公司必须满足伊斯兰法律规定的定性和定量标准。之前的研究主要集中在合规共同基金、银行和股票市场指数。我们的论文通过将单个公司的横截面分为合规公司和不合规公司,并通过分析这两类公司在COVID-19危机期间的股票表现,脱颖而出。我们的实证研究包括2020年前两个季度股票收益和波动率的季度横截面回归,以及2020年2月24日至4月17日COVID期间每日股票表现的日差异回归。我们发现,在疫情期间,合规股票的表现优于不合规股票。我们强调,这种优异的表现与更高的公司特定风险或总风险无关。

The Performance of Compliant Stocks During the COVID-19 Crisis
The outbreak of the COVID-19 pandemic led to a sharp decline in the market value of the global equity markets. The purpose of this paper is to answer the following question: Do Compliant firms outperform the Non-Compliant during the COVID-19 pandemic? A compliant firm must satisfy the qualitative and quantitative criteria defined by Islamic law. Previous research focused on Compliant mutual funds, banks, and stock market indexes. Our paper stands out by sorting the cross-section of individual firms into Compliant and Non-Compliant firms and by analyzing the stock performance of both groups during the COVID-19 crisis. Our empirical investigation includes quarterly cross sectional regressions of stock returns and volatility during the first two quarters of 2020 and daily difference-in-difference regressions of daily stock performance during the COVID period starting from February 24th to April 17th of 2020. We find that Compliant stocks outperform the Non compliant peers during the pandemic. We highlight that this out-performance is not associated with higher firm-specific or total risk.
