The S&P/TSX Composite Index Explained
The S&P/TSX Composite Index (often called the TSX Composite or simply the TSX) is Canada’s benchmark equity index. It measures the performance of approximately 220–250 of the largest, most liquid companies listed on the TSX.
The index is maintained by S&P Dow Jones Indices in partnership with TMX Group and is reviewed quarterly for constituent changes. A company must meet minimum size and liquidity requirements to be included.
What the index tracks
- Number of constituents: ~220–250 companies (varies with quarterly reviews)
- Coverage: Approximately 70% of total TSX market capitalization
- Weighting method: Market-cap weighted (larger companies have more influence)
- Largest cap in the index: Typically Royal Bank of Canada or Shopify
- Rebalancing: Quarterly (March, June, September, December)
The TSX Composite is a float-adjusted, market-cap-weighted index — meaning the weighting of each stock reflects how much of it is actually available for public trading (excluding closely held shares).
TSX Sector Breakdown
The TSX Composite is structurally very different from the S&P 500. Canada’s resource wealth means the index is heavily concentrated in three sectors:
| Sector | Approximate Weight |
|---|---|
| Financials | ~32–35% |
| Energy | ~15–18% |
| Materials (mining, gold) | ~12–15% |
| Industrials | ~9–11% |
| Information Technology | ~8–10% |
| Consumer Discretionary | ~4–5% |
| Communication Services | ~4–5% |
| Utilities | ~3–4% |
| Consumer Staples | ~2–3% |
| Health Care | ~1–2% |
| Real Estate | ~2–3% |
Financials, Energy, and Materials together represent approximately 60–65% of the entire index. This concentration means the TSX is heavily influenced by commodity prices (oil, gold, copper) and Canadian bank earnings.
TSX vs S&P 500: Key Differences
| Feature | TSX Composite | S&P 500 |
|---|---|---|
| Country | Canada | United States |

| Currency | CAD | USD |
| Largest sector | Financials (~33%) | Technology (~30%) |
| Technology weighting | ~9% | ~30% |
| Energy weighting | ~17% | ~4% |
| Materials weighting | ~13% | ~2.5% |
| Total market cap | ~$3.5T CAD | ~$45T USD |
| Major companies | RBC, TD, Shopify, Enbridge, CNR | Apple, Microsoft, Nvidia, Amazon |
| Dividend yield | ~2.5–3.0% | ~1.3–1.5% |
Performance comparison: TSX vs S&P 500
The two indexes tend to move in different cycles:
| Period | TSX Return (CAD) | S&P 500 Return (CAD) | Winner |
|---|---|---|---|
| 2000–2009 (“lost decade”) | +55% cumulative | −9% cumulative | TSX |
| 2010–2019 | +75% cumulative | +275% cumulative | S&P 500 |
| 2020 (COVID crash/recovery) | −6% (full year) | +16% | S&P 500 |
| 2021 | +22% | +28% (CAD) | S&P 500 |
| 2022 | −6% | −13% (CAD) | TSX |
| 2023 | +12% | +24% (CAD) | S&P 500 |
| 2024 | +18% | +28% (CAD) | S&P 500 |
The TSX tends to outperform during commodity bull markets (2000s, 2021–2022); the S&P 500 tends to outperform during technology bull markets (2010s, 2023–2024). Over the very long run, the S&P 500 has outperformed the TSX, largely due to higher technology and innovation exposure.

TSX Sub-Indexes
The TSX family includes several sub-indexes:
| Index | What It Tracks |
|---|---|
| S&P/TSX Composite | ~230 largest TSX companies |
| S&P/TSX 60 | 60 largest (blue-chip) TSX companies |
| S&P/TSX SmallCap | Smaller TSX-listed companies |
| S&P/TSX Venture Composite | TSX Venture Exchange (junior/small companies) |
| S&P/TSX Dividend Aristocrats | Companies with rising dividends for 5+ years |
| S&P/TSX Capped REIT | Real estate investment trusts |
| S&P/TSX Global Gold | Gold mining companies globally |
The S&P/TSX 60 is the most commonly traded sub-index. ETFs tracking it (like iShares XIU) are among the highest-volume traded securities in Canada.
How to Invest in the TSX Index
The simplest and lowest-cost way to gain exposure to the TSX Composite is through a Canadian equity ETF:
| ETF | Index Tracked | MER | Notes |
|---|---|---|---|
| XIC (iShares Core S&P/TSX Capped Composite) | S&P/TSX Capped Composite | 0.06% | Most popular Canada index ETF |
| VCN (Vanguard FTSE Canada All Cap) | FTSE Canada All Cap | 0.05% | Broader than XIC, includes smaller caps |
| XIU (iShares S&P/TSX 60) | S&P/TSX 60 | 0.18% | Oldest and most liquid Canadian ETF |
| ZCN (BMO S&P/TSX Capped Composite) | S&P/TSX Capped Composite | 0.06% | Similar to XIC |
| TTP (TD S&P/TSX Composite) | S&P/TSX Composite | 0.04% | Very low MER |
Buying TSX index ETFs
- Any Canadian online brokerage (Questrade, Wealthsimple Trade, TD Direct Investing, RBC Direct Investing, CIBC Investor’s Edge) allows you to buy these ETFs
- All can be held in a TFSA, RRSP, FHSA, or RESP
- No foreign withholding tax issues (unlike holding US ETFs)
- Dividends from Canadian equity ETFs receive the dividend tax credit in a non-registered account
The TSX and Commodities
The TSX’s heavy weighting toward energy and materials means its performance is closely linked to global commodity prices:
- Rising oil prices → Energy sector companies (Enbridge, TC Energy, CNQ, Suncor) gain → TSX rises
- Rising gold prices → Gold miners (Barrick, Agnico Eagle, Wheaton Precious Metals) gain → TSX rises
- US tariffs on Canadian goods → Resource sector earnings affected → TSX faces pressure
- Falling USD vs. CAD → Canadian commodity revenues reported in USD feel pressure in CAD terms
This commodity sensitivity is why the TSX has historically had different performance cycles than the US market — and why Canadian investors are often advised to hold both Canadian and global equity exposure.
Is the TSX a Good Investment?
For Canadian investors, holding TSX exposure provides:
✅ Currency match — No FX conversion costs; dividends and returns in CAD
✅ Dividend tax credit — Eligible dividends from Canadian corporations receive preferential tax treatment in non-registered accounts
✅ Home bias advantages — Familiar companies, regulatory environment you understand
✅ Higher dividend yield — TSX yields 2.5–3% vs. S&P 500 at ~1.5%
⚠️ Concentration risk — 65% in three sectors (financials, energy, materials) limits diversification
⚠️ Smaller tech weighting — Misses out on the global technology growth that has driven S&P 500 returns
⚠️ Smaller market — Fewer investment options compared to the US market
Most Canadian financial planners recommend a portfolio with exposure to both Canadian equities (TSX) and global/US equities (S&P 500), rather than a Canada-only approach.
