What you'll need: Internet connection, computer or smartphone, access to your European brokerage account
European small-cap ETFs offer investors a practical way to tap into the growth potential of Europe’s smaller companies, while spreading risk across hundreds of firms. In this step-by-step guide, you’ll learn exactly how to select, buy, and integrate European small-cap ETFs into your portfolio, with actionable instructions for popular brokers, real ETF examples, and EUR-based performance data.
As we covered in our complete European ETF investing playbook, building a diversified portfolio often means going beyond large caps. Small-cap ETFs can be a powerful tool—if you understand the unique risks and rewards.
Step 1: Understand What Makes Small-Cap ETFs Unique
What to do: Learn the definition of small-cap, how small-cap ETFs are constructed, and why they behave differently from large-cap funds.
Why it matters: Small-cap stocks (typically companies with a market capitalization between €300 million and €2 billion) are less researched, more volatile, and can offer higher growth—but also higher risk—than their large-cap peers. ETFs tracking these stocks let you invest broadly, reducing the risk of betting on a single company.
- Small-cap ETFs invest in hundreds of smaller European companies, providing instant diversification.
- UCITS-compliant ETFs are designed for European investors, offering strong investor protections and tax advantages.
What can go wrong? Small-cap indexes can be more volatile, and ETFs tracking them may have higher bid-ask spreads (trading costs), especially in turbulent markets.
Pro Tip
Check whether your ETF is UCITS-compliant. This is crucial for European investors for regulatory protection and tax reasons. For more, see our in-depth UCITS ETF guide.
Step 2: Weigh the Benefits and Risks of European Small-Cap ETFs
What to do: Assess whether small-cap exposure fits your financial goals and risk tolerance.
Why it matters: Small-cap stocks often outperform large-caps over the long term, especially during economic recoveries. However, they can underperform in downturns, and their prices can be more volatile.
- Benefits:
- Growth potential: Small-caps can grow faster than mature large-caps.
- Diversification: Their returns often differ from large-caps, smoothing portfolio performance.
- Access: ETFs let you invest in hundreds of companies at once, with a single trade.
- Risks:
- Liquidity risk: Small-cap shares can be harder for the ETF to buy/sell quickly, leading to wider spreads.
- Volatility: Price swings can be significant—expect double-digit drawdowns in bad years.
- Higher costs: Small-cap ETFs usually have higher expense ratios than large-cap funds.
What can go wrong? Overweighting small-caps can increase your portfolio's risk beyond your comfort level. Make sure your overall asset allocation remains balanced.
Pro Tip
Use small-cap ETFs as a “satellite” holding, not the core of your portfolio. For a simple core-satellite approach, see our 3-ETF portfolio guide.
Step 3: Compare the Top European Small-Cap UCITS ETFs
What to do: Choose from the leading small-cap ETFs available in Europe, comparing costs, index coverage, and performance—all in EUR.
Why it matters: Not all ETFs are created equal. Some track different indexes, have higher costs, or are less liquid. The right ETF should be UCITS-compliant, EUR-denominated or hedged, and available on your chosen platform.
| ETF Name (Ticker) | Index Tracked | TER (%) | Fund Size (€m) | 1Y Perf. (EUR, %)* | Dividend Policy |
|---|---|---|---|---|---|
| iShares MSCI Europe Small Cap UCITS ETF (IE00B3VWMM18 / IEUS) | MSCI Europe Small Cap | 0.58 | 1,200 | 15.2 | Accumulating |
| SPDR MSCI Europe Small Cap Value Weighted UCITS ETF (IE00BSPLC298 / ZPRX) | MSCI Europe Small Cap Value Weighted | 0.30 | 195 | 13.8 | Distributing |
| Xtrackers MSCI Europe Small Cap UCITS ETF (IE00BGHQ0G80 / XESC) | MSCI Europe Small Cap | 0.30 | 95 | 14.9 | Accumulating |

What can go wrong? Choosing an ETF with low assets under management (AUM) or low trading volume can mean higher spreads and risk of fund closure. Always check AUM (ideally €100m+), daily trading volume, and whether the fund is accumulating or distributing dividends (to match your tax strategy).
Pro Tip
Compare total cost of ownership, not just the TER. See how to avoid hidden ETF costs for a full breakdown of spreads, swaps, and taxes.
Step 4: Buy Your Chosen ETF on a European Platform
What to do: Open or log in to a European brokerage, search for your chosen ETF by ISIN or ticker, and place a buy order.
Why it matters: Not all brokers offer all ETFs. Using a platform designed for Europeans ensures access to UCITS funds, EUR trading, and local tax documentation.
- DEGIRO: Search by ISIN (e.g., IE00B3VWMM18 for IEUS), click “Buy”, enter the amount in EUR, review order type (market or limit), and confirm. You should see your ETF appear in your portfolio within minutes (or after market close).
- Trade Republic: Tap Search → enter ETF name or ISIN → select ETF → tap Buy → enter EUR amount → confirm. For savings plans: Tap Portfolio → Savings Plan → Select ETF → set monthly amount (min. €1).
- Scalable Capital: Click Invest → ETFs → search by name/ISIN → Buy → enter amount → confirm. Optionally, set up an ETF savings plan (“Sparplan”).
- Interactive Brokers EU: Use the web platform, search for the ISIN, select the European listing, choose quantity (or EUR amount), and submit your order.
Expected outcome: After placing your order, you should see the ETF in your portfolio, with the invested EUR value and number of shares displayed. For savings plans, your next monthly purchase will be scheduled automatically.
What can go wrong? Placing market orders during low-liquidity hours may result in higher spreads. Always check the bid-ask spread before confirming, and consider using limit orders for large amounts (€5,000+).
Pro Tip
Many brokers offer free ETF savings plans for selected funds. This lets you automate monthly investing—even with small amounts like €25 or €50. For more, see our DCA guide.
Step 5: Integrate Small-Cap ETFs into Your Portfolio
What to do: Decide what percentage of your portfolio to allocate to European small-cap ETFs, and adjust your holdings accordingly.
Why it matters: Small-caps should typically be a minority “satellite” position—often 5–20% of your equity allocation—rather than your entire stock exposure. This balances growth potential with risk management.
- Example: If you have a €20,000 portfolio with 70% in global equities, you might allocate 10% of equities to European small-caps:
€20,000 × 70% = €14,000 equities
€14,000 × 10% = €1,400 in small-cap ETF - Rebalance annually to maintain your target allocation, selling or buying as needed.
What can go wrong? Letting your allocation drift too high after a strong run can increase risk. Conversely, selling after a downturn can lock in losses. Stick to your plan and rebalance on a set schedule.
Pro Tip
Consider your total global small-cap exposure. Many broad all-world ETFs (like VWCE or IWDA) already include a small percentage of small-caps. Avoid accidental overlap—see our overlap guide for details.
Common Mistakes
- Overconcentration: Putting too much into small-caps increases risk and volatility.
- Ignoring costs: Focusing only on TER and missing hidden costs (spreads, taxes, FX fees).
- Neglecting liquidity: Buying ETFs with low volume/AUM can make selling difficult.
- Chasing past performance: Basing choices solely on last year’s returns can backfire.
- Forgetting to rebalance: Letting allocations drift can alter your risk profile.
Next Steps
- Review your current portfolio and decide how much small-cap exposure fits your goals.
- Compare small-cap ETF options on your broker—check ISIN, AUM, and costs.
- Set up a test purchase or a small savings plan (€25–€50/month) to get started.
- Track performance and rebalance annually.
