How to Rebalance Your ETF Portfolio in Europe: Step-by-Step (With Trade Republic & DEGIRO Screenshots)

Rebalancing your ETF portfolio is essential for keeping your investment risk in check and sticking to your long-term strategy. In Europe, the process is straightforward but requires attention to platform specifics, tax rules, and timing. This tutorial walks you through every step, with real examples and instructions for Trade Republic and DEGIRO users in 2026.

For a broader overview of ETF strategy, see our Essential 2026 Guide to European ETF Portfolio Strategies.

Step 1: Review Your Current Portfolio and Target Allocation

What to do: Start by listing all your ETF holdings, their current values, and your target allocation percentages. For example:

• iShares Core MSCI World UCITS ETF (IE00B4L5Y983): €7,000 (current), Target: 70%
• Xtrackers MSCI Emerging Markets UCITS ETF (IE00BTJRMP35): €3,000 (current), Target: 30%

Total portfolio value: €10,000

Why it matters: Rebalancing only makes sense if you have a clear benchmark for your allocations. This forms the basis for all calculations and ensures your risk profile is maintained.

What can go wrong: Guessing your targets can lead to overexposure to certain regions or sectors, increasing your risk.

Step 2: Calculate the Difference Between Actual and Target Allocations

What to do: For each ETF, calculate:

• Target value = Total portfolio value × Target %
• Difference = Target value − Current value

Example:

• MSCI World: Target = €10,000 × 70% = €7,000; Difference = €7,000 − €7,000 = €0
• MSCI EM: Target = €10,000 × 30% = €3,000; Difference = €3,000 − €3,000 = €0

If, however, the World ETF grew to €7,700 and EM dropped to €2,300, your differences would be:

• MSCI World: €7,000 − €7,700 = −€700 (need to sell €700)
• MSCI EM: €3,000 − €2,300 = +€700 (need to buy €700)

Why it matters: This step tells you exactly how much to buy or sell. Without it, you risk making unnecessary or incorrect trades.

What can go wrong: Forgetting to update your portfolio value or using outdated prices can throw off your calculations.

Step 3: Decide on Rebalancing Method (Sell-Buy or Buy-Only)

What to do: Choose whether to sell overweight ETFs and buy underweight ones, or just use new cash to top up underweight positions.

• Sell-Buy: Sell part of the ETF that's above target and use proceeds to buy the underweight ETF.
• Buy-Only: Inject fresh cash and buy only the underweight ETF(s).

Why it matters: Selling triggers capital gains tax in many European countries, while buying with new cash is usually tax-neutral.

What can go wrong: Failing to account for tax on gains or transaction fees can reduce your returns. If you must sell, check your broker’s tax reporting tools.

Step 4: Place Rebalancing Orders on Trade Republic

What to do:

1. Open the Trade Republic app or website and log in.
2. Tap Portfolio to view all your holdings.
3. To sell part of an ETF: Select the ETF (e.g., MSCI World), tap Sell, enter the € amount (e.g., €700), and confirm.
4. To buy an ETF: Select the underweight ETF (e.g., MSCI EM), tap Buy, enter the amount (e.g., €700), choose market or limit order, and confirm.
5. Review the confirmation screen for fees and order details.

Expected outcome: You should now see pending orders in the “Orders” tab. Once executed, your portfolio values should be closer to your targets.

Why it matters: Trade Republic offers commission-free ETF orders but check for potential spread costs, especially outside regular market hours.

What can go wrong: Placing large market orders during volatile periods can result in poor execution prices. Always double-check the order summary before confirming.

Step 5: Place Rebalancing Orders on DEGIRO

What to do:

1. Log in to your DEGIRO account via web or app.
2. Go to Portfolio to see your current ETF positions.
3. To sell: Click the ETF (e.g., MSCI World), select Sell, enter the number of shares (calculate based on the € difference and current price), and confirm.
4. To buy: Click your underweight ETF (e.g., MSCI EM), select Buy, enter the number of shares to match your target, choose order type, and confirm.
5. Review all order details, including expected transaction fees and FX costs if applicable.

Expected outcome: After execution, your ETF weights should reflect your intended allocation. DEGIRO shows updated portfolio values in real-time.

Why it matters: DEGIRO charges low fees but be aware of their “Free ETF List” which can help you avoid commissions if you pick from it.

What can go wrong: Rounding issues may prevent you from reaching your exact target, especially if ETF prices are high. Always check the minimum tradeable unit (usually 1 share).

See DEGIRO’s official help center for platform-specific guidance.

Step 6: Confirm Execution and Update Your Records

What to do:

• After your orders are filled, check your portfolio screen for updated ETF values and allocations.
• Update your spreadsheet or tracking tool with the new values and percentages.
• Save or screenshot the order confirmations for your records and tax reporting.

Expected outcome: Your ETF portfolio should now reflect your target allocation as closely as possible, minus rounding differences.

Why it matters: Documenting rebalancing actions is vital for annual tax filing and performance review.

What can go wrong: Forgetting to record your trades may complicate future tax reporting or portfolio reviews.

Step 7: Consider Tax Implications and Timing

What to do:

• Check if any ETF sales resulted in capital gains. In most European countries, sales outside tax-advantaged accounts (like a German Freistellungsauftrag or French PEA) may be taxable.
• Record the acquisition and sale dates, prices, and gains/losses for each trade.
• Prefer rebalancing at year-end or after major market moves, rather than too frequently.

Why it matters: Taxes can eat into your returns. Infrequent, strategic rebalancing may reduce your tax burden and transaction costs.

What can go wrong: Ignoring taxes can lead to unexpected bills. Always check your national rules and consult a tax advisor if unsure.

Common Mistakes When Rebalancing ETF Portfolios in Europe

• Rebalancing too often: Leads to high fees and unnecessary taxable events. Once or twice a year is enough for most investors.
• Ignoring minimum trade sizes: Especially on DEGIRO, where some ETFs have high share prices. You may need to round to the nearest share.
• Not accounting for FX costs: If your ETF trades in USD or GBP, currency conversion fees may apply.
• Missing tax consequences: Selling ETFs can generate capital gains taxes — plan ahead.
• Forgetting to update your allocation targets: Your goals or risk tolerance may change over time. Review your targets annually.

Next Steps

• Set a calendar reminder to review your portfolio and rebalance every 6 or 12 months.
• Consider automating contributions to underweight ETFs, which can reduce the need for selling. See our guide: How to Automate Your ETF Investing in Europe.
• Explore defensive or thematic ETFs if your allocation needs to evolve. For long-term strategy, refer to our Pillar Guide.
