报告主题:投资者关注度与并购早期公告 Investor Attention and Early Announcements in Mergers and Acquisitions

主讲人介绍:秦淮,伦敦大学玛丽皇后学院金融学博士。研究方向:公司金融、并购市场、金融市场、公司治理。

主办单位:北京师范大学湾区国际商学院

报告内容:本文以2005—2018年美国上市公司为研究样本,借助网络爬虫技术获取公司投资者关注度和并购早期公告相关数据,实证探究二者对上市公司股票价值影响。研究结果表面,上市公司的并购早期公告显著增加了投资者关注度。投资者关注度具有调节效应,能够提高并购早期公告事件对上市公司短期股价的影响。然而,这种关系在并购整合后被逆转,导致上市公司的长期价值降低。对于投资者关注度低的并购早期公告事件,短期股价提升效应和长期价值反转都不存在。本文的实证结果支持由投资者关注度带来的价格压力假说,对信息披露监管及投资者关注度等研究领域提供政策启示。

We focus on the market reaction to early announcements in mergers and acquisitions (M&A) and find that acquiring firms attract substantial investor attention with their early announcements. The positive relationship between early announcements and M&A short-term value effect is more pronounced for early-announced deals with greater investor attention toward deal announcements. However, this relation is reversed after merger integration, leading to a lower long-run firm value. For early-announced deals with low investor attention, neither the boosting effect of short-term value effect nor the price reversal in the long run exists. Our findings support the price pressure hypothesis for early announcements.
