<em><span lang="IN">The covid-19 pandemic has triggered fluctuations in the Indonesian Stock Exchange (IDX), particularly between 2020 and 2021. Using data from 720 institutional investors from the four largest banks in Indonesia with the Growth, Value, and GARP investment styles, as well as investors from domestic, Asia, and Non-Asia, this study aims to determine how institutional investors reacted during the pandemic and whether differences in investment style and location influenced investors' stock investment decisions. This study employed the Kruskal-Wallis test of variance as the omnibus test, followed by Dunnett's Multiple Comparison Test. Only investors with high investment values (above $98.7 thousand) exhibited investment dynamics, with investment values increasing from pre-pandemic levels. On the other hand, there is no discernible distinction between investors with moderate investment values. We also find that investment style has no effect on the dynamics of institutional investors' investment value. The allegation of a home bias is also unproven due to the fact that investment dynamics can only be observed in non-Asian investor groups, which increased investment relative to pre-pandemic levels. In contrast, there is no significant difference between periods regarding the amount of investment made by domestic and Asian investors. This study's findings support behavioral finance references in the context of institutional investors, who are less susceptible to behavioral biases and have a distinct rationality than the average individual investor.</span></em>
