How to Build Your First Portfolio: Core and Satellites

6 min readCompound

Key takeaways

Beginners often think that investing means picking individual stocks. The reality is more boring — and more effective: a handful of well-chosen ETFs and a clear structure is all you need. The most widely used approach is "core and satellite".

Core (60–80% of the portfolio)

A broad, low-cost and globally diversified foundation that makes up most of the portfolio and requires no attention. Typically an S&P 500 (CSPX) or a global index. It is diversified, cheap and has historically grown reliably. You are not looking for excitement here — you are looking for peace of mind and compound growth.

Satellites (20–40%)

Smaller positions that "spice up" the portfolio according to what you believe in. From the ETF overview, for example:

Golden rule: the higher the expected return, the higher the risk and volatility. Satellites have the potential to boost returns, but they fall deeper in a crisis. That is why they make up only a smaller portion — the core keeps the ship stable.

Do not forget rebalancing

Once a year, check whether satellites have grown too large (after a good year they can easily expand from 10% to 18%), and bring the weights back. You are thereby selling high and buying low — automatically and without emotion.

Specific model portfolios (from "Maximum Growth" to "Dividend Income") and their projections can be found in the growth calculator.

FAQ

How many ETFs do I need?

Anywhere from 1 to 4 is fine. More funds do not automatically mean better diversification — one broad index already covers hundreds to thousands of companies.

What is rebalancing?

Returning to target weights: selling part of an oversized position and buying more of the lagging one. It keeps portfolio risk under control.

Do I have to pick individual stocks?

No. Index ETFs hold an entire basket of companies at once, so there is no need to bet on individual names.
