Asset allocation — the percentage of your portfolio split between stocks, bonds, and other asset classes — is the single most important investment decision you'll make. Research consistently shows that asset allocation explains more than 90% of long-term portfolio performance variation. Getting this right matters far more than which specific stocks or ETFs you choose.
Why Asset Allocation Matters
Stocks (equities) offer higher long-term returns but with significant short-term volatility. Bonds offer lower returns but stability and protection during equity market declines. Your allocation determines how much your portfolio will drop during a bear market — and whether you'll be able to stay invested without panic-selling.
The "right" allocation isn't about maximizing returns — it's about maximizing the returns you'll actually receive after staying invested through bad markets. A 100% equity portfolio that falls 40% and causes you to sell is worse than a 70/30 portfolio that falls 25% and you hold through.
Age-Based Allocation Rules of Thumb
Several popular guidelines help set starting points for asset allocation:
| Rule | Formula | Example (Age 35) |
|---|---|---|
| Classic rule | 100 minus age = % stocks | 65% stocks, 35% bonds |
| Modern rule | 110 minus age = % stocks | 75% stocks, 25% bonds |
| Aggressive rule | 120 minus age = % stocks | 85% stocks, 15% bonds |
These are starting points only. Your specific situation — income stability, risk tolerance, time horizon, other assets — should shape your final decision.
Sample Canadian Portfolios by Stage of Life
Young Investor (25–35): Aggressive Growth
Or simply: 100% XEQT (which is itself a globally diversified equity portfolio). Time horizon of 30+ years means short-term volatility is irrelevant. Maximize growth.
Mid-Career (40–55): Balanced Growth
Equivalent to holding XGRO. Still heavily equity-weighted with enough bonds to reduce drawdowns during market crises.
Pre-Retirement (60–65): Conservative Growth
Moving toward preservation. XBAL (60/40 ETF) is a suitable single-fund option. Higher bond allocation reduces sequence-of-returns risk.
Retirement (65+): Income-Focused
Protecting capital while still maintaining growth to combat inflation over a 20–30 year retirement.
Geographic Allocation: How Much Canada?
Many Canadian investors over-weight Canada due to familiarity. Canada represents only about 3% of global market capitalization, yet many portfolios hold 30–50% Canadian equities. While some home bias is reasonable (no currency risk, dividend tax credit), over-concentration in Canada exposes you to sector risk (financials/energy/materials dominate the TSX).
A reasonable geographic allocation for a Canadian: 20–30% Canada, 40–50% US, 20–30% international developed markets, 5–10% emerging markets. All-in-one ETFs like XGRO and VGRO already reflect these reasonable weights.
Bonds in a Rising Rate Environment
Bond prices fall when interest rates rise (and vice versa). After the rate hikes of 2022–2023, bonds are now offering better yields than they have in 15 years. A short-duration bond ETF (like VSB or PSB) has lower interest rate sensitivity than a broad bond ETF and may be appropriate for conservative investors in uncertain rate environments.
Rebalancing Your Allocation
Over time, strong equity returns will shift your allocation — a 70/30 portfolio might drift to 80/20 after a bull market. Annual rebalancing keeps you at your target allocation. Learn how to rebalance efficiently.
Your Emergency Fund Is Part of Your Asset Allocation
