Dutch Stocks to Watch: A Guide for DEGIRO Investors

The Dutch stocks worth watching fall into four groups, and each one needs a different check before you buy. There are global giants that happen to list in Amsterdam, a cluster of chip-equipment makers led by ASML, a block of banks, insurers and consumer names, and a long tail of mid and small caps. A DEGIRO investor can buy almost all of them on Euronext Amsterdam in euros, with no currency conversion. The work is in knowing what you are actually buying.

This guide sorts the main names by type and gives you the questions that matter for each group. The companies are examples of each type, not buy recommendations, and index membership changes every quarter, so check the current lists and filings yourself.

What counts as a Dutch stock?

Here, a Dutch stock means a company whose shares trade on Euronext Amsterdam. That is a wider group than "companies from the Netherlands", and the gap matters more than most investors expect.

Euronext runs three main Amsterdam indices: the AEX for the 30 largest companies, the AMX for the next 25, and the AMS Next 20 for smaller ones (it was called the AScX until September 2025). On 30 June 2026, Euronext's AEX composition put ASML at 15.63% of the index, Shell at 14.60% and Unilever at 12.24%. Those three made up about 42% of the AEX on their own. Shell plc and Unilever PLC are British companies that earn most of their revenue far from the Netherlands.

Owning the AEX is not a bet on the Dutch economy. It is mostly a bet on chip equipment, oil and gas, and consumer staples sold worldwide. Keep that in mind before you put an AEX tracker on top of a world ETF.

The Large Caps: Global Companies With an Amsterdam Ticker

Most of the AEX's weight sits in companies whose home market is the whole world. Shell and Unilever are incorporated and tax resident in the UK. RELX sells information-based analytics and decision tools to professional and business customers. Universal Music Group owns recorded music and music publishing businesses. Prosus is a technology investor whose biggest asset is a minority stake in Tencent, so a Prosus share is partly a Tencent position with a Dutch listing.

For these names, the useful questions are about currency and tax, not about the Dutch economy.

• Which currency does the revenue come in? A company that reports in euros but earns a large part of its sales in dollars carries a EUR/USD effect, hidden inside the share price.
• Where is the company tax resident? That decides which dividend withholding tax you pay, and it is not always the country of the listing. Shell's dividends stopped carrying Dutch dividend tax after it moved its tax residence to the UK at the end of 2021. Unilever dropped it in 2020, when the group unified under the UK PLC.

Semiconductors: The Dutch Chip-Equipment Cluster

This is the group most people mean when they say Dutch tech. Three AEX companies sell the machines that chipmakers use, and on 30 June 2026 they made up about 23% of the index between them.

• ASML builds lithography systems and is the only maker of extreme ultraviolet (EUV) machines, which print the smallest features on advanced chips.
• ASM International makes deposition equipment and is the leading supplier of atomic layer deposition tools, which build up films one atomic layer at a time.
• Besi (BE Semiconductor Industries) makes chip assembly and packaging equipment, including hybrid bonders, a stacking technique that chipmakers are adopting for AI processors and high-bandwidth memory.

These are capital-goods businesses, and they move with the chip cycle. Revenue follows how much chipmakers decide to spend on new fabs, so orders and backlog tell you more than last quarter's profit. Customer lists are short, which concentrates the risk. Export controls are a standing issue as well: ASML has not shipped an EUV machine to China since 2019, when the Dutch government stopped issuing export licences under US pressure, and the restrictions have widened since.

The bigger trap is concentration in your own portfolio. Hold all three, a world ETF and a semiconductor fund, and one industry cycle can drive a large share of your returns. Our look at European AI infrastructure stocks covers how these names have traded on AI demand.

Banks, Insurers and Consumer Names

ING, ABN AMRO, NN Group and ASR Nederland sit in the AEX next to Heineken, Ahold Delhaize and KPN. Dutch investors often hold this group for income. For the banks and insurers, the dividend is only part of what comes back to shareholders, because share buybacks can be as large. Read the capital return policy in the annual report instead of judging the dividend alone.

Adyen is the odd one out: a payments platform that investors hold for growth, not income.

Mid and Small Caps: Where Research Pays Off

Below the AEX, the AMX and the AMS Next 20 hold companies that rarely make international headlines. A few examples from the June 2026 lists:

• Signify (formerly Philips Lighting) makes lamps, light fixtures and lighting control systems.
• Basic-Fit runs one of Europe's largest chains of low-cost gyms.
• Fugro collects and analyses geo-data, including seabed surveys for offshore wind farms.
• Pharming sells rare-disease medicines: Ruconest for hereditary angioedema and Joenja for APDS, a rare immune disorder.
• TomTom sells maps and location technology to carmakers and businesses.
• Alfen makes EV chargers, energy storage systems and grid equipment.

The first four were in the AMX and the last two in the AMS Next 20. These names need different checks from the large caps.

• Liquidity. Fewer shares change hands, so the gap between the bid and ask price can be wide. Use limit orders on DEGIRO, not market orders.
• Product concentration. A company with one or two main products, like Pharming, rises or falls on those products.
• Balance sheet. Smaller companies have less room to absorb a bad year. Compare net debt with earnings before you look at the growth story.
• Index moves. A name can move between indices at a quarterly review. That changes which index funds must hold it, but it says nothing about the business.

How to Check a Dutch Stock Before You Buy It on DEGIRO

Run these five checks on any company before it goes on the watchlist:

1. Read what it sells and where. The revenue split by region in the annual report tells you whether you are buying the Netherlands, Europe or the world.
2. Check the tax residence. A company that is tax resident in the Netherlands withholds 15% Dutch dividend tax. If you live in the Netherlands, it counts as a prepayment against your income tax. If you live elsewhere, how much you can reclaim depends on the tax treaty with your country. Our guide to dividend withholding tax in Europe walks through the reclaim.
3. Check the trading line. Amsterdam shares trade in euros, so a euro DEGIRO account pays no conversion. A Dutch company listed only abroad is different: DEGIRO's 0.25% currency conversion fee applies on the way in and again on the way out. The DEGIRO fees breakdown has the rest of the schedule.
4. Look at liquidity for anything outside the AEX. Check average daily volume and the spread before you place the order.
5. Check what you already own. A world ETF already holds ASML, Shell and Unilever. Add individual Dutch names on top, and your real exposure may be larger than it looks.

Dutch residents have one more layer to think about. Box 3 taxes your investments as wealth rather than taxing each sale, and the system is in the middle of a reform. The Box 3 explainer tracks where that stands.

Turn the Watchlist Into a Portfolio You Can See

A watchlist is easy to keep. Knowing how much of your money has ended up in chip equipment, or in companies that earn in dollars, gets harder once a few years of buys pile up. Import your DEGIRO transactions into a tracker and look at allocation by sector and country, not at the list of tickers.

Zune.Money's DEGIRO portfolio tracker builds that view from the DEGIRO CSV export. It shows quickly whether your Dutch picks spread your risk or double down on what your ETF already holds.
