In one line: Asset allocation is how you split money across the broad classes — and it shapes a portfolio's behaviour more than almost anything else.
Once you know the asset classes, the next question is how much of each. That split is called asset allocation, and it is the quiet decision doing most of the work behind any portfolio.
What does asset allocation mean?
Allocation is simply the proportion of each class you hold — how much in global equities, how much in bonds, how much in cash, and so on. Written out, it is a list of slices that add up to the whole.
Why does asset allocation matter so much?
How you divide between growth and steadier classes tends to shape your experience — both the long-term growth potential and the size of the swings — more than the finer details within any single class. Get the broad mix right for your situation, and the rest matters less than people expect.
What sets the right mix?
Two things lead: your time horizon and your comfort with ups and downs. A longer horizon can usually carry more of the growth-focused classes; a shorter one or a lower tolerance leans steadier. There is no single "correct" allocation — only one that fits a situation.
Why is allocation always shown by class, within ranges?
A useful allocation is described by asset class, never by specific products, and a curated profile keeps each slice inside a sensible range. The point is a balanced whole that suits you, not chasing any single number.
Key takeaways
- Allocation is the proportion of each asset class you hold.
- It shapes growth potential and swings more than picking within a class.
- Time horizon and comfort with risk set the right mix.
- It is shown by class, within curated ranges — never specific products.
