Dear Liz: If I plan to stay invested for more than 15 years and I can tolerate the ups and downs of the market, why would I want to put any of my 401(k) money into bonds instead of putting it all in various stock funds? The bond funds in my 401(k) have a five-year return of 5% to 6% whereas the other funds are 8% to 13%.
Answer: If you look at the more recent performance of those bond funds, you’ll notice that their returns are considerably worse. Many have been losing money lately as interest rates have risen. That poor performance may worsen if the economy improves and rates continue to rise.
But you need to consider more than recent performance when allocating your portfolio. Bonds and cash can cushion your account against big downturns in the stock market. That can help keep you from panicking and selling at a bottom.
If you’re as risk tolerant as you think and decades away from retirement, you might be able to put as little as 10% of your portfolio into bonds and cash. If you’re 15 to 20 years from retirement, a 20% bond allocation may be more prudent. A fee-only financial planner can help advise you about sensible asset allocations, or you can check out the stock and bond mixes of target date funds offered by leading mutual fund companies (such as the Vanguard Target Retirement 2030 Fund, if you’ll be retiring around 2030).
