What is a major characteristic of equity-indexed annuities?

A major characteristic of equity-indexed annuities is that they provide a guaranteed minimum return. This feature is designed to give investors a safety net; regardless of how the linked equity index performs, the annuity will offer a minimum return on the initial investment. This characteristic is appealing for individuals who want to participate in potential market gains while also protecting themselves against market downturns.

Equity-indexed annuities combine a fixed interest rate with the potential for additional returns based on a stock market index, but they distinctly include a guarantee that protects the investor's principal. This is a vital aspect for those who are risk-averse or looking for a more stable investment option in volatile markets.

The other options do not accurately reflect the nature of equity-indexed annuities. High fees can vary, but they aren't a defining characteristic. They are linked to stock performance but not solely based on it, as they also incorporate a minimum guaranteed return. Lastly, claiming that equity-indexed annuities always outperform mutual funds is misleading because performance varies widely due to numerous factors, such as market conditions and the specific terms of the annuity contract.
