Analysis of the Sectoral Stock Price Index on the IDX during the Covid-19

Abstract

In this study, we want to measure the performance of the average monthly return of sectoral stock indexes in Indonesia by using the composite index (JCI) as a comparison. We want to find the winner, loser, and neutral stock indexes. We use monthly data from March 2020 to February 2021, namely the sectors: agriculture, mining, essential industry, various industries, consumption, property, infrastructure, finance, and trade. We use panel data analysis from the event study to achieve the research objectives, a combination of cross-section data and time-series data. The research results showed six sectors of the stock index as winners: agriculture, mining, essential industry, infrastructure, finance, and trade. There are three loser stock index sectors: the miscellaneous sector, consumption, and property.
