Abstract

This study delves into the impact of reversals and investor attention on cryptocurrency returns before and during the COVID-19 pandemic. We employ the Two Stages Least Squares to analyze a sample of the top 20 cryptocurrencies from January 2016 to April 2021. Our results reveal that investor attention positively influences bitcoin returns in both periods, with a more pronounced effect during the pandemic. Conversely, reversals demonstrate a positive correlation with cryptocurrency returns before the outbreak but a negative relationship during the pandemic. Our robustness test further indicates that investor attention positively affects the returns of small and medium-cap cryptocurrencies, while reversals only exhibit positive consequences for small-cap cryptocurrencies. Additionally, our findings highlight stablecoins as a safe haven during the epidemic. The results suggest that investor attention has little influence on the returns of stablecoins, indicating that these coins are primarily resistant to market sentiment due to their inherent stability. The negative impact of the pandemic on the crypto market demonstrates a downward trend through each wave. Despite aligning with attention-induced price pressure and behavioral finance hypotheses, our results do not support efficient market theory or the notion of heterogeneity among investors. This research provides valuable insights for investors and policymakers in devising effective strategies for the cryptocurrency market.

摘要

本研究探讨了反转和投资者关注度对新冠疫情前后加密货币收益的影响。我们采用两阶段最小二乘法分析了 2016 年 1 月至 2021 年 4 月期间排名前 20 的加密货币样本。研究结果表明,在两个时期,投资者关注度均对比特币收益产生正向影响,在疫情期间的影响更为显著。相反,反转在疫情爆发前与加密货币收益呈正相关,但在疫情期间呈负相关。我们的稳健性测试进一步表明,投资者关注度对中小市值加密货币的收益产生正向影响,而反转仅对小市值加密货币产生正向影响。此外,我们的研究结果强调稳定币在疫情期间是一种避险资产。研究结果表明,投资者关注度对稳定币收益的影响较小,这表明由于稳定币的固有稳定性,这些货币主要不受市场情绪的影响。疫情对加密货币市场的负面影响通过每一波都呈现出下降趋势。尽管与注意力引发的价格压力和行为金融学假说一致,但我们的研究结果并不支持有效市场理论或投资者异质性的观点。本研究为投资者和政策制定者在制定有效的加密货币市场策略方面提供了有价值的见解。
