TVM and risk-return relationship are two fundamental principles of finance. Discuss briefly the possible implications of these two principles for your retirement planning. There are two basic types of retirement plans: DB versus DC. What are the main differences? If your employer sponsors a DC plan (e.g. 401(k)), what are the available investment options in terms of asset class? Describe the main characteristics of these investment options e.g. return-risk profiles and investment styles including passive vs. active management etc. (If youre not in a DC plan, answer this question based on a DC plan in general.)
