How to Build Your First Simple Portfolio from 2 ETFs

5 min readCompound

Key takeaways

Two ETFs in a portfolio are enough to cover the entire world of equities and bonds and sleep soundly at night.

Why two ETFs and not one

One global equity ETF is a great start. But equities can fall 30–50 % in the short term. Someone who also holds bonds in their portfolio sees a smaller loss during a crash — because bonds behave differently from equities. That way they don't panic and don't make a mistake. Building a first portfolio is explored in more detail in how to build your first portfolio.

Which two ETFs to choose

Tip: A simple formula for the equity-bond ratio: subtract your age from 110. The result is the approximate equity share as a percentage. Are you 30? 80 % equities, 20 % bonds. Are you 50? 60/40. It's not a science, but a good starting point.

How to maintain the portfolio

Once a year, check whether equities have grown so much that their share has exceeded your target. If so, buy more bonds in the coming months — or sell part of the equities. This process is called rebalancing. Once a year is sufficient for beginners.

When to move to a more complex portfolio

The answer is: you never have to. Thousands of successful investors hold only two or three ETFs for their whole life. Complexity is not an advantage. Simplicity that you stick to beats a complex strategy that you abandon.

FAQ

Do I have to have bonds in my portfolio, or is one equity ETF enough?

It depends on your investment horizon and psychological resilience. If you're investing for 20+ years and can endure a 40 % drop without selling, one equity ETF is sufficient and simpler. Add bonds if fluctuations stress you out or you have a shorter horizon.

How do I know if I have the right equity-bond ratio?

The right ratio is the one at which, in the worst crisis, you won't panic and sell. If you're not sure, start more conservatively (e.g. 60/40) and increase the equity share as your experience grows.

What is rebalancing and do I have to do it?

Rebalancing is restoring the fund ratio to the original target. If equities have grown and now make up 75 % instead of the planned 60 %, you buy more bonds or sell part of the equities. Once a year is enough and it takes ten minutes.
