Abstract
Herding behavior, in which investors follow overall market trends rather than conducting independent analysis, has significant implications for market efficiency, volatility, and liquidity conditions, particularly in emerging markets like Indonesia. This study aims to investigate the presence and dynamics of herding behavior in Indonesia’s LQ-45 index during three distinct periods: pre-pandemic (2019), pandemic (2020–2021), and post-pandemic (2023). The sample comprises 22 firms consistently listed on the LQ-45 index, with daily data collected from 2019 to 2023. A time-series regression based on the Cross-Sectional Absolute Deviation (CSAD) model measured herding intensity, while a Granger causality test assessed the relationship between herding behavior and market liquidity. The results indicate that herding behavior intensified significantly during the pandemic, evidenced by a strong negative γ₂ coefficient (–0.0124, p = 0.0026) and an adjusted R² of 0.1902, the highest across all periods. In contrast, the pre-pandemic period showed relatively weak herding behavior under more stable market conditions, while the post-pandemic phase demonstrated a return to more independent decision-making. The Granger causality test confirmed a bidirectional relationship between market liquidity and herding during the crisis, while such causality was absent after the pandemic. In the pre-pandemic period, herding influenced liquidity (p = 0.014), while no significant causal relationships were found afterward. Overall, herding behavior increased during the pandemic but returned to more independent decision-making in the post-pandemic phase.
