Big promises but skimpy returns plague equity-indexed annuities. By Kimberly Lankford, Contributing Editor September 1, 2010 The pitch is compelling: Participate in the stock market's upside and avoid the downside. That's how sales agents who collect lucrative commissions peddle equity-indexed annuities. Their targets are baby-boomers who are trying to rebuild their nest eggs and are now fearful of the stock market and frustrated with bonds' low interest rates.Most equity-indexed annuity contracts promise that you will never lose money, even if the market index declines. But these costly products give you only a portion of the market's gains, and their protection against loss is minimal. If you're looking for principal protection, consider buying a deferred variable annuity with guaranteed benefits (see Lock In Your Retirement Income). Sponsored Content Fuzzy math. Despite the title, equity-indexed annuities don't actually invest in the stock market. Your returns may be loosely based on a market index, but you get a lot less than investors in the actual index would receive because of caps on returns and other limitations. For example, if Standard & Poor's 500-stock index returns 26% this year, as it did in 2009, investors in some of the Phoenix Companies' equity-indexed annuities would receive just 6.5% or less -- fairly typical for these products. Some equity-indexed annuities offer higher caps but reduce your returns by other means, such as restricting your participation rate to 80% of an index's increase or subtracting a fixed percentage (a spread rate) from the index's return. Worst of all, these limitations can change even after you've purchased the annuity. Plus, you may be locked in to the investment for seven to ten years and pay a penalty if you cash out early. Advertisement Indexed annuities are regulated as insurance products, not securities, so they offer few of the usual required disclosures to help you decipher their fees, calculate performance or even figure out how the money is invested. And the new financial-reform bill would keep it that way; it bars the Securities and Exchange Commission from implementing a rule to oversee them.
