You chose an asset allocation — say 80% stocks, 20% bonds — because it matched the risk you could actually live with. Then the market moved. After a strong year, that portfolio quietly becomes 87/13; after a crash, 70/30. Rebalancing is the maintenance habit that steers it back to the mix you chose. It takes about ten minutes a year, and the hardest part isn't the math — it's that doing it correctly always feels wrong.
Rebalancing means selling a slice of whatever has grown past its target and buying whatever has fallen below it, restoring your chosen percentages. Its job is risk control, not return boosting. An 80/20 portfolio that drifts to 90/10 during a bull market is a riskier portfolio than the one you signed up for — and it reaches maximum risk precisely when the market is most expensive. Rebalancing keeps the risk dial where you deliberately set it.
Any extra return is a side effect, not the goal. Over most long periods, an ever-drifting stock-heavy portfolio actually ends higher — because stocks usually beat bonds — but it gets there with crashes deep enough to shake people out entirely. A nurse who rebalances holds a portfolio she can keep holding. The one who panic-sells a drifted 92/8 in a crash loses more than any rebalancing "cost."
| Method | How it works | Best for |
|---|---|---|
| Calendar | Once a year, on a date you'll remember (birthday, license-renewal month), check and reset to target | Almost everyone — simplest habit that works |
| 5% bands | Act only when an asset class drifts 5+ percentage points from target (80/20 becomes 85/15 or 75/25) | People who check quarterly anyway and want fewer, better-timed moves |
Both beat the real-world alternative, which is never rebalancing at all. Checking more often than quarterly adds nothing but anxiety; research on rebalancing frequency consistently shows the differences between reasonable schedules are tiny. Pick one trigger, write it down, and stop thinking about it in between.
Where you rebalance matters as much as when:
First, redirect new money. While you're contributing every paycheck, you can usually rebalance without selling anything — point your payroll contributions at the underweight asset until the mix corrects. Many 403(b) portals also let you change future-contribution percentages separately from your current balance.
Second, trade inside tax-advantaged accounts. Sales inside your 403(b), 457(b), Roth IRA, or HSA trigger no taxes. If you hold your bonds there — as good asset-location practice suggests — nearly all rebalancing can happen where the IRS can't see it.
Last, and rarely, touch the taxable account. In a taxable brokerage account, selling winners realizes capital gains. Prefer directing new deposits and dividends to the underweight fund; if you must sell, favor long-term lots — and a down market is the tax-free time to rebalance there, which pairs naturally with tax-loss harvesting.
If you'd rather never do this manually, two clean options exist. A target-date fund rebalances internally and adjusts its glide path as you age — one fund, zero maintenance. A balanced index fund (a fixed 60/40 or 80/20 inside one ticker) does the same without the drift over time. Both make the annual checkup optional. What doesn't work is owning a target-date fund plus five other funds — the automation only helps if the automated fund is the portfolio.
Once a year: (1) add up every account — 403(b), 457(b), Roth, HSA, taxable; (2) compute your actual stock/bond split; (3) if it's within a few points of target, close the laptop; (4) if not, redirect contributions and trade inside tax-advantaged accounts until it isn't; (5) note it in the same place you track your FIRE number. Done. This is also the natural moment to run a quick fee audit on whatever you own — same login, same spreadsheet, once a year.
