摘要
本研究旨在从异常收益、交易量活动、市值和国外净卖出等方面分析哪些行业受到了首位新冠肺炎患者宣布和新常态宣布的影响。所使用的样本是包括在康普斯100指数中的股票。数据分析采用事件研究非参数统计方法Corrado秩检验、Wilcoxon符号秩检验和统计参数配对样本t检验,使用Microsoft Excel和SPSS version 26应用程序。研究结果表明,宣布首例新冠肺炎患者对所有行业的平均异常股票收益没有显著影响。然而,在活动结束后的第五天,除科技板块外,所有板块都出现了显著的负异常回报。周期性消费部门和非周期性消费部门受影响最大,平均异常收益为负。非周期性消费部门也经历了净对外销售的增长。此外,在新常态政策宣布实施时,这两个行业在周期性消费领域的平均交易量增加和非周期性消费领域的市值增加方面都经历了良好的复苏。在确诊第1名患者后的第5天,只有科技行业没有受到明显影响。
INDONESIAN CAPITAL MARKET INVESTORS’ REACTION TO THE EVENTS OF THE COVID-19 PANDEMIC
This study aims to analyze which sectors are affected by the announcement of the first Covid-19 patient and the announcement of the new normal in terms of abnormal returns, trading volume activity, market capitalization, and net foreign sell. The samples used were stocks included in the Kompas 100 index. Data were analyzed using an event study non-parametric statistical approach to Corrado rank test, Wilcoxon Sign Rank test, and statistically parametric paired sample t-test using Microsoft Excel and SPSS version 26 applications. The results of the study show that the announcement of the first Covid-19 patient did not have a significant impact on the average abnormal stock return in all business sectors. However, on the fifth day after the event, there was a significant negative abnormal return in all sectors other than the technology sector. The cyclical consumer sector and the non-cyclical consumer sector were the most affected with a negative average abnormal return. The non-cyclical consumer sector also experienced an increase in net foreign sell. Furthermore, these two sectors experienced a good recovery at the time of the announcement of the implementation of the new normal policy in terms of increasing the average transaction volume in the cyclical consumer sector, and in terms of increasing market capitalization in the noncyclical consumer sector. The technology sector was the only sector that was not significantly affected on the fifth day after the announcement of the first Covid-19 patient.
