Investment Diversification: What It Is and How to Do It

Diversification means spreading your money across different investments so that a bad outcome in any single one doesn't wreck your entire portfolio — it's one of the few genuinely free ways to reduce investment risk.

Diversifying Within Canadian Equities

The TSX (see the stock market data on this site) is dominated by a few sectors — financials, energy, and materials make up a large share of the index — so owning a handful of Canadian stocks can leave you more concentrated in those sectors than you might realize. Spreading holdings across sectors, or using a broad-based Canadian equity ETF, addresses this more directly than picking a few individual names.

Diversifying Beyond Canada

The Canadian stock market represents a small fraction of the global economy, so many Canadian investors intentionally hold US and international equity exposure alongside domestic holdings — commonly through low-cost ETFs — to avoid being fully dependent on the performance of a relatively small, sector-concentrated market.

Diversifying by Asset Class

Beyond stocks, diversification also means mixing asset classes with different risk profiles — equities, fixed income (bonds or GICs), and cash — based on your time horizon and risk tolerance. A portfolio 100% in equities behaves very differently in a downturn than one balanced across asset classes.

Frequently Asked Questions

Is owning several TSX stocks enough diversification?
Not necessarily — the TSX is concentrated in financials, energy, and materials, so a handful of Canadian stocks can leave you more exposed to those sectors than you'd expect. A broad-based ETF spreads that risk more directly.
Why do Canadian investors often hold US or international stocks too?
Because the Canadian market is a small share of the global economy and concentrated in a few sectors — adding international exposure reduces dependence on any single country's or sector's performance.
What is diversification by asset class?
Mixing investment types with different risk profiles — equities, fixed income like bonds or GICs, and cash — rather than holding only one type, so your portfolio doesn't move in lockstep with any single market.
Does diversification guarantee I won't lose money?
No. It reduces the risk of a single investment sinking your entire portfolio, but diversified portfolios can still lose value, especially in broad market downturns.
