The Short Answer

Buy an all-world index ETF through a low-cost broker. Set up automatic monthly investments. Done.

That's it. That's the strategy that beats 90% of professional fund managers over the long term. Not because it's clever, but because it's simple, cheap, and removes the human tendency to make emotional mistakes.

If you want to understand why this works, keep reading. If you just want to start, jump to our step-by-step guide.

Why All-World Index Funds

An all-world index fund owns a small piece of every major publicly traded company on Earth. We're talking 3,000+ companies across every sector: technology, healthcare, energy, finance, consumer goods, everything. Every country: US, Europe, Japan, emerging markets, all of it.

Why does this matter?

Diversification without effort. When one sector crashes, others often hold steady or rise. When one country's economy struggles, others compensate. You don't need to guess which industry or region will outperform. You own them all.

Historical returns. The global stock market has returned roughly 7-10% annually over the long term, after inflation. Not every year (some years you lose 30%, others you gain 25%), but averaged over decades, that's the track record. No savings account, no bonds, no real estate comes close to this long-term average.

Why not pick individual stocks? Because you're not smarter than the market. That sounds harsh, but here's the data: over 15-year periods, roughly 90% of professional fund managers (people who do this full-time with teams of analysts) fail to beat a simple index fund. If the professionals can't do it, why would you?

The stock pickers who beat the market are mostly lucky, not skilled. And you can't tell the difference until it's too late.

Index funds don't try to beat the market. They are the market. And that's exactly why they win.

Here are specific funds to look at. These are examples as of 2026. Verify current options and expense ratios before investing.

For US Investors

VT (Vanguard Total World Stock ETF)

Alternative: VXUS + VTI (international + US separately) gives the same exposure with slightly more control over allocation.

For EU Investors

VWCE (Vanguard FTSE All-World UCITS ETF)

Alternative: IWDA + EMIM (iShares developed + emerging markets) is another solid combination.

Accumulating vs. Distributing

EU investors have a choice: accumulating funds automatically reinvest dividends, while distributing funds pay dividends to your account as cash.

For building wealth toward FIRE, accumulating is usually better. You avoid the hassle of reinvesting dividends manually, and in many EU countries, it's more tax-efficient until you start withdrawing.

Note: Tax laws vary by country. If you're dealing with large amounts, consult a tax professional in your jurisdiction, or a fee-only advisor who works with early retirees.

Trusted Brokerages

A good broker should be: cheap (low or zero trading fees), reputable (won't disappear with your money), and convenient (automatic investing, fractional shares).

What to Look For

The Power of Consistency

Here's the uncomfortable truth: when you invest matters far less than whether you invest consistently.

People obsess over timing. "Should I wait for a dip?" "Is the market overvalued?" "What about the recession everyone's predicting?"

Stop. You can't time the market. Nobody can, not consistently. Studies show that even professional traders fail at this. The market has predicted nine of the last five recessions.

Dollar-cost averaging is the antidote to timing anxiety. You invest the same amount every month regardless of what the market is doing. When prices are high, you buy fewer shares. When prices are low, you buy more shares. Over time, this averages out to a reasonable price. More importantly, it removes emotion from the equation.

Example: You invest €200 every month for 20 years at 7% average annual return.

Compound growth is not exciting in year one. Or year five. But somewhere around year ten, the curve starts bending upward in a way that feels almost unfair. That's the magic, as long as you stay consistent long enough to see it.
