摘要


Song and Walkling (2000)發現被併公司之對手公司普遍會有正向異常報酬,並提出併購機率假說作為解釋,本研究從被併公司與其對手公司角度來檢視併購謠言對股價的影響,以美國的上市公司為例,樣本期間為1985年至2010年1月底有併購謠言之美國被併公司及其對手公司,利用市場模式與三因子模式探討當有併購謠言時,被併公司是否具有異常報酬,且對手公司是呈現蔓延效果或是競爭效果,同時也探討澄清效果,當主併公司或被併公司針對謠言澄清時,對股價是否構成負向影響,並進一步分析影響累積異常報酬之相關因素。

並列摘要


Song and Walkling(2000)finds the rivals of acquired firms earn positive abnormal returns and develops “Acquisition Probability Hypothesis” as a explanation. This paper examines the effect of takeover rumors on the stock price of the target firms and rival firms, using market model and three-factor model to test if target firms will earn abnormal returns and the rivals of target firms will earn positive or negative returns when takeover rumors exist? Meanwhile, this paper also examines if clarification will have the negative effect on the stock price of acquiring firms and target firms, and furthermore tries to find what factor will affect the cumulative abnormal returns of target firms and rival firms.
