Recently, the stock index in the Indonesian market has been declining and continued to fall until the end of April 2020 due to the impact of the Covid-19 pandemic. In terms of efficient market theory, prospect theory and signaling theory, this study aims to analyze the relationship between risk and return in the Indonesian capital market dur- ing the Covid-19 pandemic as a manifestation of investor behavior. To test hypotheses, the correlation test, the independent sample t-test and the Cohen test for 629 public firms with 52,836 observable data are used. The findings show that for financial sectors and non-financial sectors, the fourth period differs from previous periods when the relationship between systematic risk and stock returns is positive, although only non- financial sectors have a significant effect. The results show that efficient market theory, prospect theory and signaling theory are consistent with the phenomena around the Covid-19 pandemic in Indonesia. In addition, Cohen’s test results suggest that govern- ment policies in the face of the pandemic are successful in stimulating the market.

The event continued when, on January 28, 2020, the National Disaster Management Authority announced that the Republic of Indonesia was in an emergency condition, followed by an international warning from the World Health Organization. Since those announcements, at the beginning of February 2020, the stock index in the Indonesian capi- tal market started to decline and fell to IDR 5,855.49 on average at the end of the month. The further event is the second National Disaster Management Authority’s announcement on February 29, 2020 to extend an emergency condition in the Republic of Indonesia. In March 2020, the Indonesian government took many recovery actions not only in the health field but also in economics, especially in monetary and fiscal policies. However, till the end of March2020, the capital market tended to show panic conditions, which resulted in the stock index drop to IDR 4,786.92 on average. On April 2020, the tax incentive regulation, as fiscal policy runs effectively, improved during the month. Moreover, as the monetary policy, the Central Bank of Indonesia decided to keep the rate at 4.5%. In April 2020, the stock index tended to move more steadily, although its average was only IDR 4,600.98. The aim of this study is to analyze the impact of the Covid-19 pandemic on the risk-return relationship in the Indonesian capital market between January 2020 and April 2020 as a manifestation of investor behavior in accordance with efficient market theory, prospect theory and signaling theory. 1.
