## Summary

The five-step plan to rebalance a 401(k) in 2026. Set your target allocation by age, log in to see current allocation, calculate the drift, sell high and buy low to return to target, then enable auto-rebalance every 6 to 12 months. From True North by Competitive Compass.

## The Five Steps

### Step 1: Set your target stock/bond allocation by age

The simplest rule: stock percentage = 110 minus your age, with the remainder in bonds. A 35-year-old targets roughly 75 percent stocks / 25 percent bonds. A 55-year-old targets 55 / 45. A target-date fund handles this automatically and updates the glide path each year. If your 401(k) offers a target-date fund matched to your retirement year, that is often the best one-fund solution.

### Step 2: Log in to your 401(k) provider to see current allocation

Log in to your 401(k) provider (Fidelity NetBenefits, Vanguard, Empower, Principal, Schwab Retirement Plan Services). Find the allocation pie chart. Note the current percentage in each asset class. Most providers also show the target you set when you enrolled, if you set one.

### Step 3: Calculate the drift

Subtract current from target for each asset class. A drift of more than 5 percentage points in any direction is usually the trigger to rebalance. After a strong stock market run, the equity share drifts higher than target; after a stock-market drop, equity drifts lower than target. The point of rebalancing is to systematically sell what is now overweight and buy what is now underweight.

### Step 4: Place trades to bring the portfolio back to target

In the provider's interface, find the "Change Investments" or "Rebalance" link. Two ways to rebalance: redirect new contributions only to the underweight asset until the percentages return to target (slow but no selling), or sell the overweight inside the 401(k) and buy the underweight (fast, no tax inside a 401(k), no trade cost). Most providers have a one-click "Rebalance to Target" button.

### Step 5: Enable auto-rebalance every 6 or 12 months

Every major 401(k) provider has an auto-rebalance setting that automatically runs the rebalance trades every 6 or 12 months. Turn it on. This converts rebalancing from an active task you must remember into a passive system. The 5 minutes once a year (or zero minutes with auto-rebalance) returns 0.3 to 0.6 percentage points of annual return over 30 years.

## Frequently Asked Questions

### What is rebalancing a 401(k)?

Rebalancing a 401(k) is the periodic act of restoring your account to a target stock/bond allocation. As markets move, the percentages drift. Rebalancing sells the overweight asset class and buys the underweight, returning the portfolio to its target risk level. Inside a 401(k), rebalancing is tax-free and usually trade-free.

### How often should I rebalance my 401(k)?

Once or twice a year is enough for most investors. The simplest schedule is to rebalance every January or every July. Rebalancing more often (monthly or quarterly) does not improve returns and adds complexity. A drift of more than 5 percentage points from target is the secondary trigger between scheduled rebalances.

### What is the right stock/bond allocation for my age?

A common rule is to hold a percentage of stocks equal to 110 minus your age, with the remainder in bonds. A 30-year-old targets roughly 80 percent stocks / 20 percent bonds. A 60-year-old targets 50 / 50. A target-date fund matched to your retirement year does this automatically and updates the glide path each year.

### Does rebalancing a 401(k) trigger taxes?

No. Trades inside a 401(k), a Roth 401(k), an IRA, or a Roth IRA do not trigger taxes. Tax applies only when you withdraw money. This means rebalancing is essentially free inside a retirement account. The same trades in a taxable brokerage account would generate capital gains tax.

### Should I rebalance my 401(k) during a market crash?

Yes, rebalancing during a crash is exactly when the discipline pays off most. A crash makes your bond percentage drift higher than target; rebalancing forces you to sell some bonds and buy stocks at lower prices. This is mechanically buying low. Most investors who panic during a crash do the opposite (sell stocks) and lock in the loss.
