Abstract

The Covid-19 Pandemic in Indonesia was first announced by the government at the beginning of March 2020. It was then followed by PSBB policies that affected the national economy. PSBB affected the reduction of public consumption. This caused many businesses to slow down. BUMN is a state-owned enterprise engaged in strategic industries. Not only receiving government support and guarantee but BUMN also has strong fundamentals and thereby the shares are sought-after by investors. The BUMN20 Index is a collection of selected BUMN with the best stock price performance. This study aims to determine whether, during the pandemic, investors can construct the optimal portfolios on the BUMN20 stock index using a single index model. The results of data analysis revealed that all BUMN20 index stocks during the coronavirus period experienced a positive mean return but with a very small value. The largest mean return was on Kalbe Farma stocks at 1.10% and the smallest on BBNI stocks at 0.04%. The single index method calculation resulted in negative ERB and Ci values for all stocks. Hence, the investors could not establish optimal portfolios during the Covid-19 pandemic.
