Why They're a Good Idea

Annuities are a long-term investment. The idea is to receive payments over the course of many years. The economy will be growing in some of those years, but slumping in others. Those low times are a natural part of the economic cycle, but they can last for years.
Market-value-adjusted annuities help you by making your investment more diverse. At any given time, some parts of your annuity could be getting a higher interest rate than other parts. If you take your payment from the part earning less interest, that will leave your other money to keep growing at a faster rate.
Because each part has a separate “guarantee period,” you’re more protected from the market’s inevitable ups and downs.
