How would a core-satellite portfolio have suited you?

What this is about

On eToro you can copy another investor's portfolio. You choose an amount, and eToro repeats their buys and sells in your own account, in proportion. You can also do this with several portfolios at once.

This page is built the same way, only looking back. In the middle is a core, the portfolio of Ludwig Marx. Around it are satellites: other portfolios that round out the mix. How big the core is depends on you. The more risk you are fine with, the smaller it gets.

Core by profile: Safety first 60%, Cautious 50%, Balanced 40%, Growth 30%, Aggressive 20%.

Here is how it works:

1. You answer six questions about how you handle risk. That sets your profile and the size of the core.
2. We look through 11 other portfolios for the satellites that would have fit best from January 2021 to October 2026. Then we show what your money would have turned into.
3. Then the honest part: what would you have picked back then, without knowing what came next? And how would that have gone?

Good to know:

• The numbers for Ludwig Marx are a backtest of the strategy up to May 2025. From June 2025 on, they come from the real eToro portfolio. All other portfolios are real portfolios from the start.
• The calculation resets the shares to where they started every twelve months. On eToro this does not happen by itself. You would have to do it by hand once a year.
• Costs and taxes are not included. A copy on eToro usually starts at 200 USD (as of 04.11.2026).
• This page only looks back. It does not know what will suit you in the future.
