Abstract:
This research paper analyses the impact of COVID-19 to investigate the overconfidence bias in 12 cyclical and defensive sectors in pre- and during COVID-19 periods using daily data from 1 January 2015 to 31 December 2020.
The results of VAR show that in the pre COVID-19 phase overconfidence bias is more prevalent in all the cyclical sectors; in particular, MEDIA, METAL and REALTY have highly significant coefficients .
In the defensive sectors, the VAR outcomes are not as strong as we expected, except for SERVICES.
During the COVID-19 period, the investor shifted their focus to COVID-19-related opportunities, leading to a surge in the IT and PHARMA sectors.
In both phases, METAL, MEDIA and REALTY exhibit overconfidence-driven stock trading behaviour.
ENERGY is the only sector in both the phases that does not witness overconfidence bias.
