How to build your own target-date retirement fund

For years, I ran my own business, and right around this time of year, I would get whipped up trying to pick mutual funds for my Individual Retirement Account (IRA).

As the April 15 tax filing deadline drew near, my accountant would shoot me the maximum amount I could contribute to my IRA based on my earnings, and then it was up to me to pick a winner, or a handful of them, to stash these retirement dollars.

As I was sweating this out one day in March, a buddy who is a sharp wealth adviser suggested I invest the lot of it in a target-date retirement fund — or take a crack at putting my own target-date fund together.

I’m not someone you would call a do-it-yourselfer. I don’t repaint bedrooms or refurnish antique tables I find at a flea market. But when it comes to my investments, I like feeling in control. Not to say that I’m a voracious self-manager who relishes researching stocks and timing buys and sells. I invest, for the most part, in market-tracking index mutual funds balanced across stocks, such as the S&P 500 index, and fixed-income bond funds.

In other words, I’m a passive investor.

That has worked for me. Index funds routinely clobber funds actively managed by professional stock pickers. And it’s why I set up my own custom target-date fund.

You might want to give it a spin too. Here’s how.

First, a recap of target-date funds.

When 401(k) plan sponsors and state auto-IRA programs automatically enroll workers in a retirement plan, the majority use target-date funds. These funds are typically made up of a couple of index funds.

You select the year you’d like to retire and buy a mutual fund with that year in its name, like Target 2035. The fund manager then splits your investment between stocks and bonds, shifting to a more conservative mix as the target date nears.

It’s set-and-forget investing for what can stretch to decades and a boon for folks who want a hands-off approach.

And for anyone who wants to be slightly more hands-on, it’s replicable.

Step 1. Pick a date and research. I started by choosing my target date, in other words, the year I expected to retire. Then I researched target-date fund families to find a fund with the date I wanted.

Some of the biggest target-date fund families include Fidelity, T. Rowe Price, and Vanguard, though most financial institutions offer them.

Step 2. Check out the fund’s holdings. Find target-date funds from a few different firms that meet your year and see what percentage of the fund is in stocks, bonds, and cash, and which particular mutual funds the target-date fund invests in. These will be the guardrails for your selections.
