- Alcoa surged 2.08% to $38.70 USD (~$54.31 CAD) on October 27, 2026, as LME aluminum inventories dropped to multi-month lows below 450,000 tonnes.
- China’s October Manufacturing PMI beat at 50.6 — its third consecutive month of expansion — provided a strong demand-side catalyst for the broader base metals complex.
- Teck Resources (TSX: TECK.B) closed at $84.45, up 2.14%, lifted by zinc and copper exposure through its Trail Operations smelter and copper portfolio.
- Nickel bucked the rally, with Vale falling 3.23% to $12.00 USD amid persistent Indonesian oversupply, pressuring Canadian producer Sherritt International’s margins.
Aluminum led the base metals complex higher on October 27, 2026, with Alcoa Corp. — the most widely followed North American aluminum proxy — climbing 2.08% to $38.70 (USD) as London Metal Exchange inventory data pointed to tightening physical supply. For Canadian investors, that translates to roughly $54.31 CAD per share at the prevailing USD/CAD rate of 1.4028. The move dragged the broader base metals complex upward, with copper adding 1.49% to $6.6050/lb and Teck Resources (TSX: TECK.B) closing at $84.45, up 2.14% on the session.
LME Aluminum Inventories Flash a Warning Sign
Aluminum stocks registered on the London Metal Exchange have declined sharply over the past six weeks, dropping to multi-month lows below 450,000 tonnes — a level that historically signals near-term physical tightness. Cancelled warrants, which indicate metal earmarked for delivery and removal from LME warehouses, spiked to roughly 28% of total on-warrant stock. Traders interpreted the drawdown as evidence that downstream consumers — particularly automotive and packaging buyers — are pulling more spot metal than expected heading into the Northern Hemisphere winter season.
China PMI Provides the Macro Catalyst
The demand-side catalyst came from Beijing. China’s official National Bureau of Statistics Manufacturing PMI printed at 50.6 for October, beating consensus estimates of 50.1 and marking a third consecutive month of expansion. Because China accounts for approximately 57% of global aluminum consumption, any uptick in factory activity has an outsized effect on price discovery. Analysts at BMO Capital Markets flagged the PMI beat as “meaningfully constructive” for the base metals outlook in Q4 2026, noting that China’s grid infrastructure buildout — which is aluminum-intensive — remains well ahead of annual targets.
Teck Resources: A Canadian Bellwether Catches a Bid
Vancouver-headquartered Teck Resources was among the biggest beneficiaries on the TSX on Tuesday. While Teck’s primary near-term revenue driver is steelmaking coal and copper following its 2024 portfolio restructuring, the company retains meaningful exposure to zinc and other base metals through its Trail Operations smelting complex in British Columbia — one of the largest fully integrated zinc and lead smelting facilities in the world. Trail processes roughly 300,000 tonnes of refined zinc annually, making Teck a direct play on any broad base metals rally. At $84.45 CAD, TECK.B is up approximately 18% year-to-date.
Nickel Remains the Outlier
Not every metal joined the party. Nickel — proxied by Vale S.A. shares — fell 3.23% to $12.00 USD, weighed down by persistent oversupply from Indonesian laterite operations. Indonesia now accounts for over 55% of global mined nickel supply, and its government has shown little appetite to curtail Class 1 nickel production quotas despite industry lobbying. Sherritt International, the Toronto-based nickel producer with operations in Cuba and a refinery in Fort Saskatchewan, Alberta, continues to face margin pressure as benchmark nickel prices on the LME hover near three-year lows. The nickel divergence is a reminder that “base metals” is not a monolithic trade: aluminum and copper are tightening while nickel remains structurally oversupplied.
| Asset | Price (USD) | Price (CAD est.) | Change |
|---|---|---|---|
| Alcoa (Aluminum proxy) | $38.70/share | ~$54.31/share | +2.08% |
| Copper | $6.6050/lb | ~$9.27/lb | +1.49% |
| Vale S.A. (Nickel proxy) | $12.00/share | ~$16.83/share | -3.23% |
| Teck Resources (TECK.B) | — | $84.45/share (TSX) | +2.14% |
With the China PMI tailwind in place and LME aluminum inventories continuing to drain, the near-term bias for aluminum and copper remains constructive. Canadian producers with diversified base metals exposure — Teck foremost among them — are well-positioned to capture the upside. The wild card remains trade policy: any re-escalation of U.S. tariffs on Canadian aluminum, a friction point that flared in 2020 and again in 2024, could quickly offset the demand-side gains now materializing from China’s factory recovery.
