Short Answer Questions

66. Discuss the differences between investors who are risk averse, risk neutral, and risk loving.

The investor who is risk averse will take additional risk only if that risk-taking is likely to be rewarded with a risk premium. This investor examines the potential risk-return trade-offs of investment alternatives. The investor who is risk neutral looks only at the expected returns of the investment alternative and does not consider risk; this investor will select the investment alternative with the highest expected rate of return. The risk lover will engage in fair games and gambles; this investor adjusts the expected return upward to take into account the \confronting risk.

Feedback: The purpose of this question is to ascertain that the student understands the different attitudes toward risk exhibited by different individuals.
