This paper investigates the relation between CEO gender and corporate bond investments using the sample of Taiwan public companies from 2007 to 2011, excluding financial and securities industries. According to prior studies, the females are cautious, conservative and risk-avoiding on investment decisions. I examine whether female CEOs prefer bonds for their investment targets and whether female CEOs are more possibly to hold bonds to maturity and to earn fixed interest income. In other words, this paper investigates whether female CEOs are more likely to invest in long-term holding bonds. The empirical results show that female CEOs tend to invest in bonds and prefer long-term holding bonds. My findings suggest that female CEOs are more cautious, conservative, and risk-aversion on investment decisions.
