The Core-Satellite Approach
A stable index core plus a few high-conviction bets — structure with room to play.
Core-satellite is a simple structure that resolves a common dilemma: should I just buy index fundsA fund that simply tracks a market index at very low cost. (safe but “boring”), or pick my own stocks (exciting but risky)? The answer is — do both, deliberately, in the right proportions.
- The Core (typically 70–90%) — broad, low-cost index fundsA fund that simply tracks a market index at very low cost.. This is your reliable engine: diversified, cheap, hard to break. It guarantees you roughly capture the market return.
- The Satellites (the remaining 10–30%) — a few high-conviction individual stocks, themes or active bets where you’re trying to add extra return.
This structure lets you scratch the stock-picking itch *without betting your futureA binding agreement to buy or sell at a set price on a future date. on it*. Even if every satellite bet fails, the big, boring core keeps your plan intact; and if a satellite wins, it meaningfully boosts returns. You get the discipline of indexing and the upside of conviction — with the downside firmly capped. The boring part is what makes the exciting part safe.

FAQs
What split should core vs satellite be?
Depends on your skill, time and risk appetite — but a common, sane starting point is 80% core / 20% satellites. The more uncertain you are about your stock-picking edge, the bigger the core should be. Never let satellites grow so large that their failure derails your goals.
