The best stock screener for European small caps and microcaps in 2026 is ScreenerHero. It covers Euronext Growth Paris, Nasdaq First North (Stockholm, Copenhagen, Helsinki), EGM Milan, and GPW NewConnect — the alternative markets where most European microcaps trade — with reliable P/E, ROE, EV/EBITDA, and margin data for names down to €10M market cap. No other screener at this price point covers European alternative markets with working fundamental filters.

Why European small cap screening is uniquely difficult
European small caps and microcaps are one of the most undercovered segments in global finance — and that undercoverage is precisely why they generate consistent alpha opportunities for systematic investors. But screening them requires infrastructure that most tools haven't built.
There are five structural reasons why most screeners fail for European small caps:
1. Fragmented exchange structure. European small caps don't trade on a single market. They trade across 12+ exchanges, each with different data formats, reporting timelines, and listing standards. A company on Nasdaq First North Helsinki, an Italian EGM issuer, and a French Euronext Growth company are legally, linguistically, and technically completely different — yet need to appear in the same screening universe. Most US-centric tools connect to one or two European data sources and call it "global coverage."
2. Alternative market exclusion. The European equivalents of the US OTC market — Euronext Growth Paris, Nasdaq First North (Stockholm, Copenhagen, Helsinki, Tallinn), EGM Milan, and GPW NewConnect (Warsaw) — list hundreds of legitimate operating businesses ranging from €10M to €500M in market cap. Most screeners either omit these markets entirely or list the tickers without usable data.
3. IFRS vs. local GAAP inconsistency. Smaller European companies often report under local GAAP rather than IFRS, particularly in earlier reporting periods. This creates inconsistencies in how P/E, EV/EBITDA, and other ratios are calculated across companies — a screener needs to normalise for this, not just display raw numbers.
4. Low analyst coverage = no consensus data. European microcaps typically have zero to two analyst reports. Tools that rely on analyst estimates (TIKR, Bloomberg) are structurally handicapped for screening names without coverage. Fundamental screening from reported financials — not estimates — is the only viable approach.
5. Thin float and low liquidity. Many European microcaps have significant insider or family ownership and limited public float. A screener that doesn't flag this creates screens where the "results" include names with €200k daily turnover — technically meeting the filters but untradeable in size.
European small cap and microcap markets explained
Before comparing screeners, it's worth clarifying which markets constitute the European small cap and microcap universe:
| Market | Country | Typical Cap Range | Companies |
|---|---|---|---|
| Euronext Growth Paris | France | €5M–€500M | ~220 companies |
| Nasdaq First North Stockholm | Sweden | €10M–€1B | ~350 companies |
| Nasdaq First North Copenhagen | Denmark | €10M–€500M | ~100 companies |
| Nasdaq First North Helsinki | Finland | €10M–€500M | ~80 companies |
| EGM Milan (Euronext Growth Milan) | Italy | €5M–€500M | ~230 companies |
| GPW NewConnect | Poland | €1M–€200M | ~380 companies |
| AIM London | UK | £1M–£500M | ~850 companies |
| BME Growth (BME) | Spain | €5M–€300M | ~110 companies |
These markets collectively list over 2,300 companies that rarely appear in US-focused screening tools. Many are profitable, cash-generative, family-run businesses that trade at deep discounts to their main-market equivalents purely because of limited coverage.
Best screeners for European small caps compared
1. ScreenerHero — Best overall for European small cap and microcap screening
Coverage of alternative markets: Full. Euronext Growth Paris, Nasdaq First North (Stockholm, Copenhagen, Helsinki), EGM Milan, GPW NewConnect, AIM London, BME Growth. These markets are included in the screening universe with working fundamental filters — not just listed as tickers without data.
Filter quality for small caps: P/E, P/B, ROE, EV/EBITDA, net margin, operating margin, revenue growth, dividend yield, debt/equity, market cap — all work reliably for European names down to microcap. Data quality flags indicate where fundamental data is incomplete for a specific company.
Market cap floor: No mandatory minimum. You can screen down to sub-€50M names. A market cap filter is optional, not forced.
Data source: End-of-day (EOD) pricing with fundamentals from regulatory filings. Not analyst estimates — actual reported figures.
Free tier: Full screener including alternative market names, no account required.
Paid plan: €29/month Pro. Unlimited results, saved screens, alerts.
Best for: Any investor systematically screening European small caps — value investors looking for overlooked quality businesses, growth investors covering Nordic tech, income investors in European microcap dividend payers.
Limitations: No real-time data (EOD only). No earnings transcripts. No analyst consensus estimates. Basic charting — not a charting platform.
2. TradingView — Good for main market small caps, poor for alternative markets
Coverage of alternative markets: Partial. TradingView has price data for many alternative market names but fundamental data (P/E, EV/EBITDA, ROE) is missing or stale for the majority of Euronext Growth, First North, and EGM companies.
Filter quality for small caps: Inconsistent. Large and mid-cap European names work well. Below €200M market cap — especially on alternative markets — fundamental filters frequently return empty or incorrect values.
Free tier: Account required even for free access. Some filter combinations restricted.
Paid plan: $15–60/month.
Best for: Technical and chart-driven investors whose primary workflow is price analysis. European large-cap coverage is good.
Not ideal for: Systematic fundamental screening of European microcaps. The alternative market data gaps make it unreliable for this use case.
3. Stockopedia — Best composite scoring for UK small caps
Coverage of alternative markets: Moderate for UK (AIM London coverage is good). Continental European alternative markets — Euronext Growth, First North, EGM — have significant gaps, particularly outside the UK.
Filter quality for small caps: Good within Stockopedia's coverage universe. The StockRanks composite scoring system (Quality + Value + Momentum) works well for UK AIM companies and larger continental European names.
Free tier: None. Trial available.
Paid plan: €60/month (Europe) · €80/month (Europe + US).
Best for: UK-based small cap investors who want composite quality/value/momentum scores. AIM coverage is strong.
Not ideal for: French, Italian, Nordic, or Polish microcap screening. Geographic bias toward UK — continental European alternative markets are underrepresented.
4. TIKR — Deep historical data, limited European microcap coverage
Coverage of alternative markets: Listed but sparse. TIKR claims 100,000+ stocks across 92 countries, but for European alternative market names, fundamental data is often missing or limited to a few metrics.
Filter quality for small caps: Better for companies with analyst coverage. European microcaps with zero sell-side coverage have limited data on TIKR because the platform aggregates analyst estimates alongside reported financials.
Free tier: Freemium with friction. Account required.
Paid plan: $40–55/month Pro.
Best for: Deep-dive research on individual companies with strong analyst coverage. Not for systematic screening of European microcap universes.
5. Finviz — US-only, irrelevant for European small caps
Coverage of alternative markets: Zero. Finviz covers US exchanges (NYSE, NASDAQ, OTC). European exchange-listed companies are not in the screening universe.
Best for: US small cap screening — it is the best US-focused screener available. For European small caps, it is not applicable.

How to build a European small cap screen
A systematic starting point for European small cap fundamental screening:
Step 1 — Define the exchange universe. Select the alternative markets relevant to your strategy. For a broad European microcap screen: Euronext Growth Paris + First North Stockholm + First North Copenhagen + EGM Milan + GPW NewConnect.
Step 2 — Set a market cap range. €10M–€500M captures the genuine small cap and microcap universe. Below €10M, liquidity becomes a concern for most investors; above €500M, most names have moved to main markets and get adequate coverage from other tools.
Step 3 — Filter for operating profitability. Operating margin > 0% removes pre-revenue and loss-making names. This alone reduces a 500-name universe to 150–250 names with genuine business operations.
Step 4 — Add a valuation filter. EV/EBITDA below 10 and P/E below 18 are reasonable starting points. European microcaps trading below these levels are either genuinely cheap or have specific problems — the job is to distinguish which.
Step 5 — Filter for financial health. Debt/Equity below 1.0 removes the over-leveraged names. For microcaps, balance sheet risk is particularly important — these companies have limited access to refinancing if things go wrong.
Step 6 — Sort and prioritise. Sort by EV/EBITDA ascending. Review the top 30–50 results. Expect 20–30% to have data quality issues (stale reporting, unusual corporate structures, subsidiaries distorting consolidated numbers). These require manual verification.
A full pan-European microcap screen on these criteria typically surfaces 40–80 companies — a workable research list for a month of deep-dive work.
The liquidity problem: a caveat for microcap investors
Screening European microcaps surfaces investment opportunities that institutional money cannot access due to size constraints. This is both the opportunity and the risk.
A company with €30M market cap and €5M daily turnover is screenable and investable for an individual investor. For a fund managing €100M, it cannot be a meaningful position without moving the price. This creates a genuine information advantage for individuals — but it also means:
- Exit risk is real. If thesis breaks, getting out quickly at a fair price is difficult for any position above €50k.
- News impact is amplified. A profit warning on a €30M cap can take it down 30% in a session with minimal volume.
- Financial reporting quality varies. Smaller companies have fewer reporting controls. Accounting anomalies are more common and harder to detect without full document review.
Systematic screening of European microcaps should always be followed by qualitative due diligence — the screen surfaces candidates, not conclusions.

What market cap qualifies as a microcap in Europe?
There is no official definition, but most European market conventions use: microcap = below €150M, small cap = €150M–€1B, mid cap = €1B–€5B, large cap = above €5B. Some sources set the microcap threshold at €300M. For practical screening purposes, filtering below €200M captures the names that institutional money typically cannot hold in meaningful size.
