How Many Holdings You Need
There is no single correct number of holdings, but there are clear ranges that are too few and too many for a beginner running their own research.
Why this matters for beginners
Too few holdings means one mistake dominates your result. Too many means you cannot follow any of them well enough to make decisions.
Main explanation
Most of the benefit of diversification arrives within the first fifteen to twenty holdings, provided those holdings are genuinely different from one another.
The practical limit is attention. Each holding needs periodic review of results and thesis, and that time is finite.
A common structure combines a broad index fund as the base with a small number of individual companies you research properly.
Position count matters less than overlap. Twenty holdings in one industry is closer to one bet than to twenty.
Example using a real company
A portfolio of one index fund plus six researched companies is usually more manageable than thirty individual holdings reviewed rarely.
- →Two holdings: one disappointment can remove a third of your capital.
- →Forty holdings: most receive no meaningful review at all.
Common beginner mistakes
- ✕Counting holdings without checking overlap.
- ✕Adding positions faster than you can research them.
- ✕Assuming more holdings always means less risk.
