    Abstract: 過去文獻顯示，市場上長期存在價值溢酬，而最近的文獻也發現，只有適當過度自信的經理人可以做出最適的投資決策，並且增加公司價值，因此，本文將公司用價值型、成長型及不同自信程度的經理人變數交叉做分組，以研究價值溢酬是否只會出現某些特定自信程度的經理人身上。本文使用ExecuComp資料庫內1997-2013年的美國公司資料去做研究，最後我們發現，在成長型公司內，只有被極度過度自信的經理人所管理的公司會產生比較差的績效；相反的，在價值型公司內，被缺乏自信的經理人所管理公司產生所有分組裡最佳的績效。另外，並非所有成長型公司績效都偏低，被適當自信程度的經理人所管理的成長型公司也可以產生好的績效，因此本篇文章認為，公司應該要依照公司特性去挑選不同的經理人以提升公司價值。
    Empirical literatures show that value stocks outperform growth stocks consistently. Recent researches also document that only the moderately overconfident CEOs make optimal investment decisions and increase the firm value. Thus, in this paper, we argue that value premium may not hold in some particular firm characteristic if value and growth firms are subdivided into firms managed with different CEO confidence level. Using a sample of U.S firms over 1997-2013 from ExecuComp, we find, in growth firms, only the firms managed by excessively overconfident CEOs results in poor performances. Besides, the value firms managed by excessively diffident CEOs earn the highest return; however, the growth firms earn a positive return when the CEOs are moderately overconfident. We show that firms should hire CEOs matched their specific characteristics to increase firm value.
