Abstract

This study centers on the short and long-term impacts of merger and acquisition announcements on acquirer firm shares. We employ event study and calendar-time portfolio approach for the short and the long-term analyses, respectively. Our findings reveal that, in the short-term, abnormal returns are possible particularly before and exactly at the announcement date, whereas only cumulative abnormal returns survive in following days. In the long-term, however, announcements do not possess a significant impact on firm value. Firm size matters for the short-term abnormal returns, but does not appear to be a significant factor in the long-term.

Özet

Bu çalışmada, birleşme ve devralma işlemlerine yönelik duyuruların alıcı firma hisseleri üzerindeki kısa ve uzun vadeli etkileri analiz edilmiş, kısa vadeli etki analizinde olay etüdü yaklaşımı; uzun vadeli etki analizinde ise, takvim zamanlı portföy yaklaşımı uygulanmıştır. Analiz sonuçları, kısa vadede, özellikle duyuru öncesinde ve duyuru gününde önemli oranda anormal getiri elde edilebildiğini; ancak daha sonraki günlerde sadece kümülatif etkinin söz konusu olduğunu; uzun vadede ise, birleşme ve devralma duyurularının hisse değerine etki etmediğini göstermektedir. Firma büyüklüğü kısa vadede anormal getiriler üzerinde belirleyici etkiye sahip iken, bu etki uzun vadeye sirayet etmemektedir.
