Asset allocation is how you split your money across asset classes — groups of investments that behave in broadly similar ways, such as shares, bonds and cash — so that each part of your portfolio (the full collection of your investments) does a different job: long-term growth, steadier income, or ready stability. It matters to beginner investors and long-term savers because the mix determines how their money is spread across asset classes.
Decide the mix before the products
An asset class groups investments with broadly similar characteristics; individual holdings can still behave differently. Allocation is the top decision — what share of your money each class holds — and specific products come second. Hong Kong's Investor and Financial Education Council (IFEC) describes the aim as a resilient portfolio: exposure spread across asset classes and reviewed regularly against your goals and your risk capacity, meaning how much loss you can afford to take without abandoning your plan.
What each class is for
- Shares (equities): for long-term growth. Prices swing widely, so they suit money you will not need for years.
- Bonds (fixed income): for steadier, income-like returns. They usually move less sharply than shares but can still lose value.
- Cash and readily accessible savings: for planned near-term payments. Check each account’s access terms before treating the money as immediately available.
Diversification — spreading exposure across different assets — can reduce concentration and volatility (how sharply prices swing), but it cannot guarantee gains or eliminate every loss.
A worked example — all figures are illustrative
Assumptions (hypothetical round numbers, not any real product's returns):
Assume no contributions or withdrawals. The returns are total returns with distributions reinvested. Ignore fees and taxes; rebalance at the stated year-end values and assume the required amounts can be traded. Actual costs would change the result.
- You invest HK$100,000.
- You choose 60% shares, 30% bonds, 10% cash — an example mix, not advice. IFEC notes that no single allocation suits everyone.
- Over one hypothetical year, shares rise 20%, bonds return 2%, and cash returns 1%.
Step 1 — year-end values:
| Class | Start | Return | End |
|---|---|---|---|
| Shares | HK$60,000 | +20% | HK$72,000 |
| Bonds | HK$30,000 | +2% | HK$30,600 |
| Cash | HK$10,000 | +1% | HK$10,100 |
| Total | HK$100,000 | HK$112,700 |
Step 2 — the mix has drifted. Shares are now 72,000 ÷ 112,700 ≈ 63.9%, bonds ≈ 27.2%, cash ≈ 9.0%. After a good year, you are carrying more risk than you chose.
Step 3 — rebalance. Rebalancing means buying and selling to restore your chosen allocation. Targets: 60% of 112,700 = HK$67,620 in shares; 30% = HK$33,810 in bonds; 10% = HK$11,270 in cash. So you sell HK$4,380 of shares and move HK$3,210 into bonds and HK$1,170 into cash (3,210 + 1,170 = 4,380). Rebalancing can incur trading costs, and there is no universally suitable interval — some investors rebalance yearly, others whenever a class drifts past a set limit.
Three common mistakes
"Diversified means I cannot lose." Correct reading: diversification can reduce concentration and volatility, but no mix can guarantee gains or remove every loss. Plan for down years.
"Start by picking the winning fund." Correct reading: allocation comes first. Decide each class's job — growth, income or stability — then select products to fill those roles.
"Set the mix once and forget it." Correct reading: markets move and the mix drifts, as Step 2 shows. Review against your goals and risk capacity, and rebalance by rule rather than by mood.
Checklist before you act
- Write down your goal and when you will need the money.
- Give each asset class one job: growth, income or stability.
- Choose a mix you could still hold after a bad year.
- Set a review date and a rebalancing rule; note the costs of each change.
- When you are ready to choose specific funds or accounts, browse Jolvex’s product lists, then check each provider’s official terms.
