This article explores the announcement effect of foreign direct investment (FDI) on stockholders' wealth. Different from previous studies, our focus is on how growth opportunities and free cash flow make influence on FDI announcement effect. Our sample includes 236 event companies listed on Taiwan Stock Exchange during 1993-1998. Results show that: (1) announcement effect of investment in Mainland China is better than South-East Asia; (2) companies with lower growth opportunities have higher stockholders' wealth of announcement; (3) firms with more free cash flow are associated with better announcement effect; (4) companies with lower growth as well as higher free cash flow create the largest wealth effect on FDI announcement.
