신제품 공개가 전략적 제휴를 맺은 기업의 주가에 미치는 영향

Abstract

This paper studies the stock prices of the suppliers concluded strategic alliances with Samsung which preannounced new product(Galaxy S) from 2010 to 2016 through an event study. To do it, we estimate abnormal returns regarding companies listed on capital market in order to examine different market reaction. The results are follows: Preannouncement of Galaxy S had positive effect on stock price of all suppliers one day before preannouncement. Divided total samples into 2 groups(one is existing partner and another is new partner), it also had positive effect on stock price of both partners. Just new partners have more significant than existing. This study is meaningful in presenting new points in terms of strategic alliances through empirical analysis concerning enterprise value of strategic alliances with Samsung according to the preannouncement.
