Target-Date Funds: The Good, the Boring, and the Quietly Brilliant
Why the most-mocked fund in your 401(k) is also, for most people, the right answer. And the situations where it genuinely is not.
Target-date funds pick a year roughly matching when you plan to retire, hold a diversified mix of stocks and bonds, and automatically shift toward bonds as the year approaches. The investing internet loves to mock them. For most people, they are the right answer.
What they get right
They are diversified by default. They rebalance automatically. They glide-path the risk down without requiring you to think about it once a year. For the median investor who will never read a prospectus, this combination beats almost any portfolio they would have assembled themselves.
What to watch
Expense ratios vary widely. A target-date fund inside a low-cost provider's lineup is often under 0.15%; the same year inside an expensive 401(k) plan can run 0.60% or more. The fee difference compounds dramatically over thirty years.
When to skip them
If you genuinely want a different stock/bond split than the glide path provides, or if your plan only offers high-fee target-date options while offering cheap index funds alongside, building your own three-fund portfolio is reasonable. For everyone else, picking the target-date fund and never thinking about it again is a perfectly defensible choice.
