本文以事件研究法，針對台灣自1998年至2008年，曾經變更公司名稱之上市、櫃公司為樣本，探討經理人盈餘管理行為對更名公司股價之影響。實證結果顯示在公司更名前後，經理人有從事盈餘管理行為之現象，且從事積極型盈餘管理者，其股價長期累積超額報酬表現最差。此外，內部人對公司更名的看法可作為市場投資人的參考指標，惟分析師的看法卻係一反向指標。本文進一步發現經理人從事積極型盈餘管理行為時，分析師傾向看好更名公司之未來表現，表示分析師過於依賴財務報表資訊，而容易作出錯誤的投資決策；而內部人較能透析公司更名及經理人盈餘管理之行為，並利用經理人從事積極型盈餘管理行為時出脫更名公司持股，而避開了更名公司股價下跌的風險。 / In this paper, we use event-study method to examine the effect of earnings management on the stock performance of firms that changed their names. Our sample consists of firms listed on Taiwan Stock Exchange and Gretai Securities Markets from 1998 to 2008. The empirical results show managers tend to dress up financial statements before corporate name change events. Our results show that performance of firms in the most “aggressive” quartile of earnings management is the poorest. In addition, we find that trading activities of insiders provide more information than analyst recommendations to future stock performance of name change companies. We also find that analysts tend to increase EPS forecast for name change firms with aggressive earnings management. This implies that analysts rely more on financial statement information to provide their earnings forecasts. On the other hand, insiders have the ability to see through the cosmetic earnings management of name change firms. Furthermore, we find that insiders tend to sell stocks of firms engaged in aggressive earnings management to avoid the risk of declining stock prices of name change firms.
