Final answer:
For a conservative investor like Gretchen Hoffman, who needs current income and is concerned about falling interest rates, indexed bonds such as Treasury Inflation-Protected Securities (TIPS) can be an appropriate investment choice.
Step-by-step explanation:
Gretchen Hoffman is a conservative investor looking for investment options that offer current income and growth of capital. Given that she anticipates a continued decrease in interest rates, bond investments, particularly those that are indexed to inflation, such as Treasury Inflation-Protected Securities (TIPS), could be most appropriate for her. TIPS offer the advantage of protecting against inflation, ensuring that the return exceeds inflation rates, providing stability and predictability for a retiree like Gretchen. On the other hand, the stock market is generally riskier and can fluctuate, which might not align with her conservative investment strategy. Therefore, a conservative investor looking for current income and who believes interest rates will continue to fall will find an investment like TIPS to be more suitable.
