My kids' 529s are in age-based funds with lots of bonds. Is that OK if rates rise? -- Chris Berk, Westerville, Ohio
Though prices on existing bonds fall when interest rates rise, you're unlikely to face losses similar to what a bad year in stocks could generate.
Plus, 529 plans' age-based funds -- invested more conservatively as kids approach college age -- tend to hold bonds with short or intermediate maturities (less than 10 years), dampening possible declines.
Still, says Christine Benz, director of personal finance at Morningstar, if you're nervous about rates and college bills are less than five years out, you could move some of your 529 to a money-market or short-term-bond fund (maturities under five years) in your plan.
Leave money slated for college's later years or grad school untouched. And remember that you can move a 529's existing investments typically only once a year.
