S&P Dow Jones Indices on Friday evening announced the results of its quarterly review for the S&P/TSX Composite Index, revealing a definitive trend toward the resource sector. Effective prior to the opening of trading on March 23, 2026, all five companies being added to Canada’s benchmark index are focused on the precious metals and mining industries.
The upcoming rebalancing highlights a significant rotation toward gold and silver producers. The new additions to the index include:
- AbraSilver Resource Corp. (TSX: ABRA)
- Avino Silver & Gold Mines Ltd. (TSX: ASM)
- i-80 Gold Corp. (TSX: IAU)
- Montage Gold Corp. (TSX: MAU)
- Americas Gold and Silver Corporation (TSX: USA)
Classified under the Materials sector, these companies represent a mix of gold-focused explorers and diversified precious metals producers. The additions reflect the growing market capitalization and liquidity within the Canadian mining space, particularly as investors continue to look toward hard assets amid global economic shifts.
For institutional investors and exchange-traded funds that track the S&P/TSX Composite, these changes will necessitate a portfolio realignment to accommodate the increased weighting of the materials sector.
The S&P/TSX Composite Index remains the primary gauge for the Canadian equity market, covering approximately 70% of the market capitalization for companies listed on the Toronto Stock Exchange.
