An ETF is the simplest way to start investing. One purchase gives you a piece of hundreds or thousands of companies at once. Here's everything you need to know.
An ETF (Exchange-Traded Fund) is a basket of investments bundled into a single product that trades on the stock exchange like a regular stock. Instead of buying shares of one company, you buy a share of the basket, which can contain hundreds or thousands of stocks, bonds, or other assets.
Think of it like a pre-made smoothie. Instead of buying each fruit separately (Apple stock, Microsoft stock, Nestle stock...), you buy one bottle that already contains a mix of everything. One purchase, instant diversification.
Most ETFs are "index funds," meaning they automatically track a predefined list of stocks (an index) rather than having a human manager pick stocks. This makes them cheap, transparent, and consistently effective.
An index is a list of stocks with specific rules. The S&P 500 index tracks the 500 largest US companies. The MSCI World tracks ~1,500 companies from 23 developed countries. The index decides what's in the basket and how much of each.
Companies like Vanguard, iShares (BlackRock), or Amundi create ETFs that replicate the index. They buy all the stocks in the correct proportions and package them into a fund. You buy shares of that fund.
ETFs trade on stock exchanges just like individual stocks. You buy them through a broker (Interactive Brokers, Degiro, Swissquote, etc.) during market hours. You can buy and sell anytime the market is open.
When the index changes (a company is added or removed, weights shift), the ETF adjusts automatically. You don't need to do anything. The fund always mirrors the index, keeping your portfolio up to date without any effort.
If one company in your ETF goes bankrupt, it barely affects your portfolio because it's one of hundreds or thousands. With individual stocks, one bad pick can wipe out a significant chunk of your money. Diversification is the only "free lunch" in investing.
Index ETFs have expense ratios of 0.03% to 0.50% per year. Actively managed funds charge 1-2%. Over 30 years, this difference can cost you tens of thousands of euros. A 1% fee difference on a €500/month investment over 30 years costs you roughly €100,000 in lost growth.
Over a 15-year period, roughly 90% of actively managed funds underperform their benchmark index. Professional stock pickers with teams of analysts, expensive data, and decades of experience still can't consistently beat a simple index fund. Why try to do what the pros can't?
No research, no earnings calls, no worry about individual company news. Buy a world ETF every month via DCA and let compound interest do the work. This is why it's called "boring" investing. And boring investing works.
You always know exactly what's inside an ETF (the full holdings list is public). And because ETFs trade on exchanges, you can sell anytime during market hours. Your money isn't locked up.
Not all ETFs are the same. Here are the main types you'll encounter:
Tracks developed markets worldwide (~1,500 companies from 23 countries). Some include emerging markets too (~4,000 companies from 47 countries). One ETF, maximum diversification. Popular examples: MSCI World, FTSE All-World.
Tracks US companies only. The S&P 500 covers the 500 largest US companies (Apple, Microsoft, Amazon, etc.). Historically strong performance but concentrated in one country.
Focused on specific regions or countries. Useful for tilting your portfolio toward a particular area, but less diversified than a world ETF.
Dividends are automatically reinvested into the fund. Your shares grow in value instead of paying you cash. Maximizes compound growth and is simpler (nothing to reinvest manually).
Dividends are paid out to your brokerage account as cash. Useful if you want regular income (retirement, passive income). You'll need to reinvest manually if you want compound growth.
With thousands of ETFs available, choosing can feel overwhelming. Here are the five things that matter:
This is the most important decision. A world index (MSCI World or FTSE All-World) is the safest starting point. It gives you broad exposure to the global economy. You can add specific region or sector ETFs later if you want to tilt your portfolio.
The expense ratio (Total Expense Ratio / TER) is the annual fee. For a world ETF, anything below 0.25% is good. Below 0.10% is excellent. Don't pay 0.50% for an ETF that tracks the same index as one costing 0.07%.
If you're investing for wealth building (not income), pick an accumulating ETF. Dividends are reinvested automatically, keeping compound interest working without any action from you. Look for "Acc" in the ETF name.
Larger funds (€1 billion+ in assets) are cheaper to trade and less likely to close. Older funds (5+ years) have a track record you can evaluate. Avoid tiny or brand-new ETFs unless you have a specific reason.
Most European investors prefer Ireland-domiciled ETFs (ISIN starting with IE) because of favorable tax treaties with the US. This reduces the withholding tax on dividends from US companies, which are a large part of any world index.
~4,000 stocks from 47 countries (developed + emerging). Accumulating. The "one ETF to rule them all" for many European investors.
~1,500 stocks from 23 developed countries. Accumulating. Excludes emerging markets, slightly cheaper.
500 largest US companies. Very low fees. US-concentrated but historically strong performance.
~9,800 stocks from 47 countries. Extremely low fees. Similar coverage to VWCE but much cheaper.
US-listed ETF. Not available to most EU residents due to PRIIP regulations. Accessible to Swiss residents and non-EU investors.
This is not investment advice. Research any ETF thoroughly before investing. Past performance does not guarantee future results.
Buying ETFs is the easy part. Keeping track of your portfolio, contributions, and performance over time is where Boring Money comes in:
Track your ETF portfolio alongside your expenses, savings rate, and net worth.
Start tracking your investmentsA stock is a share of one single company. An ETF holds many stocks at once. Buying one share of a world ETF gives you exposure to thousands of companies across dozens of countries. An ETF provides instant diversification, while a single stock concentrates all your risk in one company.
Yes. ETFs go up and down with the market. In a crash, a world ETF can drop 30-40%. But historically, markets have always recovered and reached new highs. The key is time: if you invest for 10+ years and don't panic-sell during downturns, the odds of positive returns are very high. The S&P 500 has never had a negative 20-year period.
The price of one share, which ranges from ~€5 to ~€500 depending on the ETF. Many brokers now offer fractional shares, so you can invest any amount. There's no minimum portfolio size. Starting with €50 or €100 per month is perfectly fine. What matters is starting, not the amount.
Statistically, lump sum investing beats DCA about two-thirds of the time because markets tend to go up. But DCA (investing a fixed amount monthly) is psychologically easier and removes the stress of timing. Most people don't have a lump sum anyway, so investing from each paycheck via DCA is the practical choice.
One world ETF (like VWCE or IWDA) is genuinely enough for most people. It gives you broad diversification across thousands of companies. Adding more ETFs adds complexity without necessarily improving returns. Start simple. You can always add specific sector or bond ETFs later as your portfolio grows and your knowledge deepens.
