What asset allocation is
Asset allocation is how you divide capital among different asset classes, such as stocks, bonds, cash, and commodities. It's the highest-level decision in portfolio management, and much research shows it strongly influences long-term results, often more than picking individual assets.
Why it matters
Asset allocation determines the overall risk level you accept. A portfolio piled into one asset class carries very different risk than one balanced across several. This is where you shape the risk-and-expected-return picture of all your capital, before getting into individual trades.
How to apply it
Set the weighting among asset classes to fit your goals, time horizon, and risk tolerance. Someone accepting high risk with a long horizon usually allocates more to volatile assets; someone needing safety with a short horizon does the opposite. The key is choosing an allocation deliberately, rather than letting the portfolio form randomly from each buy and sell.
Common mistakes
- Having no deliberate allocation, letting the portfolio form randomly.
- Piling too much into one asset class because it's rising well.
- Not considering time horizon and risk tolerance when allocating.
- Forgetting allocation must be maintained over time, not chosen once and abandoned.
FAQ
- Is allocation more important than stock-picking? Much research shows allocation strongly influences long-term results, often more than picking individual assets; but both have a role.
- Is there a standard allocation formula? There's no formula right for everyone; it depends on each person's goals, horizon, and risk tolerance.
- How often should I review allocation? Review periodically and when circumstances change, rather than letting it drift with the market.
