本文研究了激进卖空者在识别做空目标时是否表现出持续的横截面业绩差异,以及他们的业绩持续性是否随着从业时间的变化而变化。利用数据提供商跟踪的激进卖空者样本,本文发现,当使用目标公司股票收益率作为业绩衡量指标时,未能发现激进...本文研究了激进卖空者在识别做空目标时是否表现出持续的横截面业绩差异,以及他们的业绩持续性是否随着从业时间的变化而变化。利用数据提供商跟踪的激进卖空者样本,本文发现,当使用目标公司股票收益率作为业绩衡量指标时,未能发现激进卖空者业绩具有持续性的证据,但如果激进卖空者过往选择的做空目标中有较高比例的公司退市,则当前做空目标在未来经历退市的可能性更大。投资者意识到了这一业绩的持续性,并且对历史做空目标中有更多退市记录的激进卖空者发起的做空行动反应更为强烈。此外,本文发现,识别做空目标的业绩持续性在激进卖空者从业生涯早期更高,但随着他们发起的做空行动增多,这种业绩的持续性会下降。这些证据与激进卖空者在职业生涯初期面临更大的声誉激励一致,并支持了Benabou and Laroque(1992)的动态声誉模型。展开更多
