Core-Satellite Investing: How It Works, Rules & Example
Core-satellite investing keeps most of your money in a steady, diversified core while a smaller slice goes into satellite ideas you are excited about. It blends the reliability of index investing with room for personal conviction.
How it works
- Build a core of 70% to 90% in broad, low-cost index funds.
- Set aside 10% to 30% for satellites such as sector funds, individual stocks or themes.
- Set clear limits on how big any single satellite can become.
- Review satellites periodically and trim or replace ideas that no longer fit.
- Rebalance so the core stays the dominant part of the portfolio.
The rules
π Pros
- Keeps a solid diversified base while allowing some active ideas.

- Flexible enough to adapt as you learn.
π Cons
