Abstract

On a 1990–2016 sample of 78,594 firm-year observations, we document strong evidence of lower stock crash risk for more prominent firms (those with greater market share). This evidence is consistent across various proxies for stock crash risk, raw versus instrumented market share, and ordinary least squares versus logistic regressions. We also find that the market share's suppressing effect on stock crash risk is weakened by the relative prevalence of long-term investors. This moderating effect of investor horizon suggests the quasi-monopolistic insulation from market pressures as the explanation for the reduction in stock crash risk among more dominant firms.

市场份额、投资者视野和股灾风险
在 1990-2016 年的 78,594 个公司年观测样本中,我们记录了强有力的证据,表明更知名的公司(市场份额更大的公司)股价暴跌风险更低。这一证据在股灾风险的各种代用指标、原始市场份额与工具市场份额、普通最小二乘法与逻辑回归中都是一致的。我们还发现,市场份额对股灾风险的抑制作用因长期投资者的相对普遍性而减弱。投资者期限的这种缓和效应表明,准垄断性的市场压力隔绝是更具支配地位的公司降低股灾风险的原因。
