Asset Allocation for Retirement, by the SEC and the Fed

Time horizon does most of the work

The SEC's Office of Investor Education has a sentence that probably ought to be tattooed on every 401(k) statement: "The asset allocation that works best for you at any given point in your life will depend largely on your time horizon and your ability to tolerate risk." That's the entire framework. No magic ratio, no favored fund family, no mention of your age in absolute years.

The reason this matters: a 32-year-old has roughly 35 years before they touch the money. A 62-year-old might start drawing on it next year. The same portfolio is reckless for one of them and ridiculous for the other. Time horizon isn't a tiebreaker between two close options. It's the input that decides almost everything else about asset allocation for retirement.

The glide path nobody invented

Read further into the same SEC investor primer and you'll find this line about how retirement investors typically behave: "most people investing for retirement hold less stock and more bonds and cash equivalents as they get closer to retirement age." That's the glide path in plain English. It isn't an industry construct. It's a description of what people actually do, because the math is brutal: a 30% stock drawdown in your 50s is a setback you can wait out, the same drawdown in your 67th year can mean cutting groceries.

Investors considering asset allocation for retirement often start with a coarse frame. When you have decades, lean toward stocks. When you have years, mix in more bonds. When you have months, hold cash for what you'll spend soon. The exact percentages matter less than the direction of travel, and the direction is one-way.

Target-date funds are the lazy person's glide path

The SEC defines a lifecycle (target-date) fund this way: "A lifecycle fund is a diversified mutual fund that automatically shifts towards a more conservative mix of investments as it approaches a particular year." That's the entire pitch. You pick a fund whose label year is roughly when you plan to retire, and the fund itself drifts from stocks toward bonds without you doing anything.

It isn't perfect. Two funds with the same retirement year can hold very different mixes, because each fund company picks its own glide path. But for someone who otherwise wouldn't rebalance once a decade, the lazy version of asset allocation for retirement usually beats the elegant version of nothing.

The 2024 readiness gap, in three numbers

The Fed's 2024 Economic Well-Being of U.S. Households report is one of the cleanest reads on where Americans actually stand on retirement. Three numbers from that survey:

The gap between "has any retirement money" and "feels on track" is huge. Part of it is that people simply haven't saved enough. But part of it is that an account holding the wrong allocation feels just as wobbly as an empty one, and from year to year it might be wobblier. A pile of cash earning nothing for a 35-year-old is technically a retirement plan and practically a missed decade. That's the everyday cost of skipping asset allocation for retirement.

A reasonable framework you can borrow

None of this is investment advice. It's the SEC's own framework, restated. Investors thinking about asset allocation for retirement often work through it in this order:

1. Pick a horizon. Years until you'll start drawing the money, not your age in absolute terms.
2. Be honest about risk tolerance. If you sold in March 2020 and didn't buy back in until 2022, your "tolerance" is whatever your behavior says it is, not whatever a questionnaire says.
3. Let stocks dominate when the horizon is long. Per the SEC, most retirement investors hold more stocks early and shift toward bonds and cash as the date approaches.
4. Pick the lazy version if you won't tend the garden. A target-date fund inside a 401(k) is the default for a reason.
5. Recheck once a year. Not once a quarter. Once a year. Pick a date, look, and put it down.

That's the entire rule book. Anyone selling you a more complicated framework is probably selling you the framework.

If you'd rather build the mix yourself instead of buying it off the shelf, a starting point is to think in two buckets: a broad equity basket (often a mix of US and international index ETFs) and a fixed-income basket (Treasuries, broad bond funds, or cash for what you'll spend soon).

Key takeaways

• The SEC says asset allocation for retirement depends on time horizon and risk tolerance, not a fixed age-based ratio.
• Most retirement investors shift from stocks toward bonds and cash as the target date approaches. That's the glide path.
• A target-date (lifecycle) fund is the auto-rebalanced version of that glide path.
• Per the Fed's 2024 survey, 67% of adults have retirement-designated assets, 61% hold a tax-preferred account, and 35% feel on track.
• Recheck your mix once a year. Not once a quarter.
