A simple global ETF portfolio

A simple portfolio is not a beginner portfolio you are meant to outgrow. For a lot of people it is the finished object: one broad fund, a cash buffer outside it, and a monthly amount. Complexity can come later if your life gets a shape that needs it. It should not come first.

What “global” should mean

A fund that tracks a global stock index owns companies across developed markets and, in many indexes, emerging markets, weighted by size. Larger companies count for more. You are not making a forecast about which country will win the decade. You are owning the listed businesses the index includes, in the proportions the index already uses.

Names you will see on European factsheets include FTSE All-World and MSCI ACWI. They are not identical. One may hold more smaller companies, or treat a country differently. For a long-term core holding, the overlap is large. Pick one you understand, with a low ongoing charge, and resist owning three versions of it. Overlap is not diversification.

What is an ETF explains the wrapper. Expense ratios explained is how to keep the holding cheap enough that simplicity is not wasted.

The one-fund version

Buy a single accumulating or distributing global equity ETF, depending on whether you want income paid out. Keep adding to it. That is the portfolio.

This version is right when your horizon is long and you can tolerate a large fall without selling. It is wrong when part of the money has a date attached. Do not hide a house deposit inside a global equity fund because the fund is “responsible.” Risk and time horizon is the filter.

The two-fund version

Add a high-quality bond fund, or simply hold more cash, for the slice you want to wobble less. The stock fund remains the growth engine. The calm slice is there so a bad equity year does not dictate your life.

There is no correct percentage. A common textbook split is something like 60 percent shares and 40 percent bonds, and it is common because it is teachable, not because it was calculated for you. Write your own split on a piece of paper. Rebalance once a year so the split does not drift into “whatever went up.”

If bonds confuse you, a larger cash holding outside the broker is an honest substitute while you learn. Cash is a poor long-term engine — see why cash loses ground to inflation — and a fine shock absorber.

What you can ignore

You can ignore sector bets, a separate technology fund that the global fund already holds in size, a second broker “for diversification,” and the urge to hedge every currency. You can ignore daily rebalancing. You can ignore anyone who calls this portfolio naive without saying which risk they are adding and why you are paid to take it.

You cannot ignore the tax wrapper available in your country, the currency conversion fee, or the difference between an Invest account and a CFD account.

Buying it in small pieces

A global ETF can have a unit price that is awkward next to a monthly transfer. Fractional shares solve that. So does a pie that contains one fund and receives the whole contribution. Both are ordinary features rather than advanced ones.

Trading 212 supports fractional Invest orders and Pies. The walkthrough of Pies is what Trading 212 Pies are useful for, and the account invite we link to is this Trading 212 referral (referral link, opens in a new tab). Open it only after you have named the fund and the monthly amount. The catalogue is not the portfolio.

A simple global ETF portfolio is finished when you can describe it to a tired friend in two sentences and you no longer feel the need to apologise for it.
