摘要

本文研究了投资者关注度对加密货币收益和交易活动横截面的影响。我们发现，与较高的谷歌异常搜索量相关联的加密货币随后表现出较高的回报率、较高的波动性和较高的交易量。这些结果对替代样本期和替代搜索关键词都是稳健的，为注意力引发的价格压力假说提供了具体支持，并与之前对股票市场的研究相一致。这种效应在规模较大的加密货币中更为明显。在最初的回报率上升之后，只观察到了部分反转，这意味着投资者的注意力对加密货币的价格产生了永久性的影响。

Google search and cross-section of cryptocurrency returns and trading activities

This paper examines the effect of investor attention on the cross-section of cryptocurrency returns and trading activities. We find that cryptocurrencies associated with higher abnormal Google search volume subsequently exhibit higher returns, higher volatility, and higher trading volume. The results are robust to alternative sample periods and alternative search keywords, providing concrete support to the attention-induced price pressure hypothesis and consistent with prior studies on the equity market. The effect is more pronounced among larger cryptocurrencies. Only a partial reversal after the initial return increase is observed, implying that investor attention permanently impacts cryptocurrency prices.
