上市櫃公司減資宣告效果之研究-以BCG模型觀點

The Research of Capital Reduction-BCG Model Perspective

指導教授 : 王朝仕

摘要


一般而言,市場對公司採取減資方式彌補虧損會產生負面反應,致使股價下跌。為瞭解投資人對不同特徵的減資公司是否產生不同反應,乃嘗試以BCG觀點,區分公司為老狗事業、明星事業、問題事業及金牛事業等四類,再使用事件研究法檢測各個特徵公司在減資宣告後的異常報酬,期望實證結果可提供管理階層與投資人擬定決策的參考。研究對象選取2004年至2014年曾辦理減資的上市櫃公司。實證結果發現,市場對不同特徵的減資公司有不同反應;其中,老狗事業及明星事業會呈負向反應,金牛事業會呈正向反應,問題事業則呈先負後正之反應。

並列摘要


Companies adopting capital reduction to offset losses generally cause negative effects in the market, thereby leading stock price falls. To examine whether investors react differently to such companies exhibiting varying characteristics, this study adopted the BCG matrix by categorizing sample companies as “Dogs,” “Stars,” “Problem Marks,” and “Cash Cows,” employing an event study method to assess the abnormal returns of each sample company that announced capital reduction; this empirical study thereby serves as a reference to management and investors regarding policymaking. The samples were listed and over-the-counter companies that engaged in capital reduction in 2004–2014. The results of this empirical study indicated that the market had various reactions to the sample companies with differing characteristics. Among these samples, “Dogs “and “Stars” caused negative reactions,” Cash Cows” caused positive reactions, and” Problem Marks” caused shifts from negative to positive reactions.
