This paper studies the relationship between the attention of investors and investment decision-making by investigating the effects of media coverage on mutual funds. It is found that investors' attention will affect their decision-making; especially in purchase decisions. Various kinds of news have different effects on decision-making: Good news leads investors to raise their inclination to purchase and redeem funds, while bad news does the contrary, ceteris paribus. In addition, performance-related information and size of funds also increase investors' tendency to purchase and redeem funds. Finally, with-or without-news funds show no significant differences in their subsequent performances.
