Planning for retirement income represents a sizeable portion of most advisors’ practices—but advisors differ on the best ways to produce that income. While mutual funds and ETFs enjoy near-universal approval as retirement planning products, there is much less agreement on annuities and life insurance products. RIAs in particular are much less likely to use guaranteed products than advisors in other channels. That’s the finding of a recent study by WealthManagement.com and FUSE Research Network, which surveyed more than 700 advisors on how they approach clients’ retirement income needs.
