摘要

结合月度调查数据和匹配的交易记录,我们研究了在2008-2009年金融危机期间,个人投资者的观念是如何改变和推动交易和冒险行为的。我们发现,在危机期间,投资者的认知波动显著,风险承受能力和风险认知的波动性小于回报预期。在危机最严重的几个月里,投资者的回报预期和风险承受能力下降,而风险感知能力上升。在危机接近尾声时,投资者的看法有所恢复。我们记录了交易和冒险行为的大幅波动,这些波动是由投资者观念的变化驱动的。总体而言,个人投资者在危机期间继续积极交易,并没有降低其投资组合的风险。

Individual Investor Perceptions and Behavior During the Financial Crisis
Combining monthly survey data with matching trading records, we examine how individual investor perceptions change and drive trading and risk-taking behavior during the 2008–2009 financial crisis. We find that investor perceptions fluctuate significantly during the crisis, with risk tolerance and risk perceptions being less volatile than return expectations. During the worst months of the crisis, investors’ return expectations and risk tolerance decrease, while their risk perceptions increase. Towards the end of the crisis, investor perceptions recover. We document substantial swings in trading and risk-taking behavior that are driven by changes in investor perceptions. Overall, individual investors continue to trade actively and do not de-risk their investment portfolios during the crisis.
