Asset allocation is how you divide your portfolio between the main types of investment: stocks, bonds and cash. It’s one of the biggest decisions you’ll make as an investor, because it largely sets how much your portfolio is likely to grow and how much it will swing along the way.
Why the mix matters
Different assets behave differently. Stocks offer higher long-term growth potential but can fall sharply, sometimes by a third or more in a bad year. Bonds tend to move less and often hold up better when stocks drop. Cash barely moves but grows slowly. Combining them lets you choose a level of risk you’re comfortable with.
Common example mixes
| Mix (stocks / bonds) | Typical character |
|---|---|
| 90 / 10 | Growth-focused, with large swings. Suits long time horizons. |
| 60 / 40 | Balanced. A classic middle-of-the-road mix. |
| 30 / 70 | Conservative and steadier, with lower expected growth. |
These are illustrations, not recommendations. The right mix depends on your goals, time horizon and comfort with risk.
How to think about your own mix
- Time horizon: the longer until you need the money, the more time you have to recover from downturns. That’s why long-term investors often hold more stocks.
- Risk tolerance: picture your portfolio falling 30%. Would you hold on, or sell? Choose a mix you won’t abandon in a downturn.
- Goals: different goals can have different mixes. Retirement savings and an emergency fund shouldn’t look the same.
Some investors use target-date funds, which hold a ready-made mix that gradually becomes more conservative as a chosen year approaches. They’re a simple, hands-off way to handle allocation.
Key takeaway
Decide on your mix first, then choose investments to fill it. Once you have a target, rebalancing keeps you on track.
