摘要
摘要本研究旨在检视投资组合的建构,并探讨影响投资组合收益的因素变量。投资组合股票推导了Elton Gruber模型,并将其与使用等加权和市值加权计算的投资组合收益进行了比较。这项研究使用的是Sri-Kehati商业指数的成分股,以及2015年1月至2022年6月的月度数据。本研究发现,使用Elton Gruber模型,有6只股票成为股票组合的成员。利用变异系数(Coefficient of Variation, CV)分析,等权重组合的变异系数最小,因此具有较好的投资组合。经t检验,三个投资组合的差异不显著。市场冲击、汇率、利率和COVID-19显著影响Elton Gruber模型的投资组合收益。等加权和市值组合只受市场冲击的影响。基于这一研究结果,这意味着当投资者使用等加权或市值加权模式时,投资者不需要基金经理来管理他们的投资组合。JEL分类号:B26、B41、C01、C13、C51、D53、E44。关键词:建设投资组合,收益投资组合,市值,等加权,油价,汇率和利率,COVID-19
Construction Portfolio Using Elton Gruber Model: COVID-19
Abstract
This research aims to examine construction of the portfolio and also to explore factor variable affected on portfolio return. Portfolio stock derived the Elton Gruber model and compared it with portfolio returns calculated using the Equal Weighted and market capitalization weighted. This research used stock that is member of the Sri-Kehati Business Index, and monthly data from January 2015 to June 2022. This research has finding that there are 6 stocks to become member of stocks portfolio using Elton Gruber Model. By using Coefficient of Variation (CV), the equal weighted has the good portfolio because it has lowest of variation. Using t-test, there are no significant differences for three portfolios. Market Shock, Exchange Rate, Interest Rate and COVID-19 significantly affect Portfolio Return of Elton Gruber Model. Equal Weighted and Market Capitalization Portfolio only affect by Market shock. Based on this research results, it has implication that Investors do not need Fund Manager to manage their portfolio if investor use equal weighted or market capitalization weighted mode.
