Dear Liz: I sold my home two years ago and still have not done anything with my gain of $200,000. It’s in a one-year certificate of deposit so at least it’s earning something while I try to figure out what to do with it. I’m 66, retired and have an IRA of $500,000 that’s invested in the market. I get $1,450 from that plus a monthly Social Security check of $1,750.

I know that my hesitation has to do with the crash of 2008. I know that things have recovered nicely but I just don’t want to feel like I did then, watching my money disappear. I don’t know if I’m the only older person who has this fear of riding it out again.

Answer: Few who watched their portfolios plunge in 2008-09 look forward to experiencing that again. But risk is inextricably tied to reward. If you want the reward of inflation-beating returns that stocks offer, you must accept the risk that your portfolio can go down as well as up.

And you probably do want that reward for a big chunk of your investments. Retirees typically need about half of their portfolio in stocks to generate the kinds of returns that will preserve their buying power and help insulate them against running short of money.

That doesn’t mean all your money has to be at risk. You still need to have a good stash of savings sitting in safe, liquid accounts to help you ride out any market downturns or emergencies. Financial planners often recommend that their retired clients keep six months’ worth of expenses in an emergency fund, and some like to see 12 months’ worth. Beyond that, though, your money probably should be working for you, not simply dwindling away to taxes and inflation.

If you find yourself unable to move forward with a plan for this money, consider hiring a fee-only financial planner who can help you review your options.
