ETF portfolio rebalancing is one of the most overlooked drivers of long-term investing success. It’s not just about “setting and forgetting”—markets move, and so do your portfolio’s risk and return. In this deep-dive, we’ll walk through hands-on, step-by-step ETF portfolio rebalancing examples Europe—using real ETF tickers, euro amounts, and screenshots from top platforms like Trade Republic and DEGIRO.
If you want the full context on why and when to rebalance, check out our complete guide to mastering European ETF portfolio rebalancing. Here, we’ll focus on practical “how-to” with three real-world walkthroughs:
- Equity-heavy portfolio rebalancing (growth-focused)
- Bond-heavy portfolio rebalancing (defensive/retirement)
- Multi-asset balanced portfolio rebalancing (classic 60/40)
We’ll use specific, euro-based numbers and actionable steps on Trade Republic and DEGIRO. You’ll see how to calculate, execute, and check your rebalancing—plus common mistakes to avoid.
Step 1: Review Your Current ETF Portfolio
What to do: Log in to your broker (e.g., Trade Republic or DEGIRO) and export or note your current ETF holdings and their values in EUR.
- Trade Republic: Tap Portfolio in the app. For each ETF, note the name, ticker (e.g., VWCE, EUNA), and current value in €.
- DEGIRO: Go to Portfolio → Overview on the web dashboard. Export or copy your ETF list and their market values.
Why this matters: You can only rebalance if you know your current allocation. Recent market moves may have shifted your weights away from your targets.
What can go wrong: Forgetting to update for recent dividends, missing small positions, or not using up-to-date prices can skew your calculations.
Pro Tip
Use a simple spreadsheet (Excel, Google Sheets) to list each ETF, its current value, and the % of your total portfolio. This makes the next steps much easier and reduces mistakes.
Step 2: Set (or Confirm) Your Target Allocation
What to do: Decide your desired allocation for each asset class and ETF. For example:
- Equity-heavy: 90% global stocks, 10% eurozone government bonds
- Bond-heavy: 30% global stocks, 70% eurozone bonds
- Multi-asset: 60% global stocks, 30% eurozone bonds, 10% gold
If you’re unsure, see our ETF construction deep dive for Europeans or defensive ETF portfolio guide.
Why this matters: Your target allocation reflects your risk tolerance, goals, and time horizon. The whole point of rebalancing is to keep your investments aligned with these targets.
What can go wrong: Picking arbitrary or inconsistent targets, or changing your plan impulsively based on recent performance.
Pro Tip
Write down your target allocation and stick to it. Revisit only if your life situation or goals change—not just because of market swings.
Step 3: Calculate the Differences (“Drift”)
What to do: For each ETF, subtract the target % from the current %. Multiply this by your total portfolio value to find how much you need to buy or sell (in €) to rebalance.
Example (Equity-heavy, €10,000 portfolio):
- Target: 90% iShares Core MSCI World UCITS ETF (EUNL/ISIN: IE00B4L5Y983), 10% Xtrackers II Eurozone Government Bond UCITS ETF (DBXZ/ISIN: LU0290355717)
- Current: 87% EUNL (€8,700), 13% DBXZ (€1,300)
Calculation:
EUNL: 87% - 90% = -3% → need to buy €300 more
DBXZ: 13% - 10% = +3% → need to sell €300
Why this matters: This step quantifies exactly what you need to do—no guesswork. It ensures you’re not “eyeballing” your allocations and drifting off course.
What can go wrong: Math errors, ignoring cash or uninvested dividends, or forgetting fees that may affect the final allocation.
Pro Tip
Some platforms and third-party tools automate this math. See our guide to the best ETF rebalancing tools and apps for 2026.
Step 4: Decide on Buy, Sell, or New Contributions
What to do: Choose how to rebalance:
- With new money: Add new funds to the underweight ETF(s) only
- By selling: Sell overweight ETF(s) and buy underweight ETF(s)
- Hybrid: Combine both, if you have some new cash but not enough
Example (Bond-heavy, €20,000 portfolio):
Target: 30% stocks (Vanguard FTSE All-World UCITS ETF, VWCE), 70% bonds (iShares Core € Govt Bond UCITS ETF, EUNA)
Current: 33% stocks (€6,600), 67% bonds (€13,400)
- VWCE: 33% - 30% = +3% → sell €600
- EUNA: 67% - 70% = -3% → buy €600
Why this matters: Selling triggers potential taxes (see our ETF rebalancing tax traps guide). Using new contributions avoids this, but may be slower.
What can go wrong: Accidentally selling too much, incurring unnecessary taxes, or not factoring in trading fees.
Pro Tip
Whenever possible, use new contributions to rebalance. This avoids triggering capital gains tax and keeps your money fully invested.
Step 5: Execute the Trades on Your Platform
What to do: Place the necessary buy/sell orders in your brokerage account. Here’s how:
-
Trade Republic:
- Tap Portfolio → select the ETF → tap Buy or Sell
- Enter the euro amount calculated above (e.g., €300), review order, and confirm
- Repeat for each ETF as required. For recurring rebalancing, adjust your Savings Plan amounts
-
DEGIRO:
- Go to Portfolio → select the ETF → click Buy or Sell
- Enter the number of units or the euro amount (as close as possible—DEGIRO trades by units)
- Review, then confirm your order. Repeat as needed
Expected outcome: You should now see your new ETF positions updated. The portfolio percentages should be much closer to your target allocation. It’s normal for allocations to be off by a small margin due to rounding or price movement during trading.
Why this matters: Actually executing the trades is what brings your portfolio back in line. Skipping this step means your plan stays theoretical.
What can go wrong: Mistyping amounts, selecting the wrong ETF, or placing market orders during illiquid trading hours—leading to poor prices.
Pro Tip
For large trades, consider using limit orders to control your purchase/sale price. This is especially important for less liquid ETFs.
Step 6: Confirm and Document Your New Allocation
What to do: After trades settle (usually same-day or next business day), check your portfolio breakdown again:
- Trade Republic: Tap Portfolio to view updated values and percentages
- DEGIRO: Go to Portfolio → Overview
Update your spreadsheet or notes with the new ETF values and percentages.
Expected outcome: Your allocation should now match your targets within a margin of error (usually <1%).
Why this matters: This step confirms your rebalancing was successful and provides a record for future rebalancing sessions.
What can go wrong: Forgetting to check, missing a trade confirmation, or not updating your records—making your next rebalance less accurate.
Pro Tip
Set a calendar reminder for your next review—quarterly or annually is common. See evidence-based strategies for rebalancing frequency.
Real-Life Example: Multi-Asset Portfolio Rebalancing
Scenario: You have a €15,000 portfolio split between:
- 60% stocks (iShares MSCI ACWI UCITS ETF, SSAC/ISIN: IE00B6R52259)
- 30% eurozone bonds (iShares Core Euro Govt Bond UCITS ETF, EUNA/ISIN: IE00B4WXJJ64)
- 10% gold (WisdomTree Physical Gold, PHAU/ISIN: JE00B1VS3770)
Current values: €8,400 stocks (56%), €5,100 bonds (34%), €1,500 gold (10%)
Drift:
- Stocks: 56% - 60% = -4% → buy €600
- Bonds: 34% - 30% = +4% → sell €600
- Gold: on target
Execution (on DEGIRO):
- Sell enough EUNA units to free up approx. €600
- Buy €600 of SSAC (as close as possible in whole units)
- Check your new allocation after trades settle
Result: Your stocks and bonds are now much closer to target, gold remains unchanged.
Pro Tip
If you can't trade exact euro amounts (DEGIRO), get as close as possible with units. Small leftover “drift” is normal.
Common Mistakes
- Ignoring taxes when selling ETFs. Always check your local rules—see our tax traps guide.
- Rebalancing too often (or not often enough). Overtrading increases costs; undertrading increases risk. See how often to rebalance.
- Forgetting to update for dividends or new contributions. Always work with up-to-date numbers.
- Using market orders during volatile periods. This can lead to poor trade execution—use limit orders for large trades.
- Not checking platform fees or minimums. These can eat into returns, especially for small portfolios.
Next Steps
- Review your portfolio at a set interval (e.g., every 6 or 12 months)
- Consider automating parts of the process—see our automation guide
