Teck Resources Plummets 4.69% Amid Merger Uncertainty and Production Woes – What’s Next for the Copper Giant?

Summary
• Teck Resources (TECK) slumps 4.69% intraday to $42.48, a sharp reversal from its $44.57 previous close.
• Anglo American’s $53B merger proposal faces regulatory scrutiny amid Teck’s 2025 copper production cut to 170K–190K tonnes.
• Quebrada Blanca mine setbacks and global copper supply disruptions fuel sector-wide volatility.

Teck Resources’ stock is in freefall as operational challenges at its flagship Chilean mine and regulatory uncertainty around its $53B merger with Anglo American collide. With copper prices hitting 16-month highs and Freeport-McMoRan’s Grasberg mine disaster compounding supply fears, investors are scrambling to assess the long-term implications for Teck’s production outlook and merger viability. The stock’s intraday range of $41.82–$42.85 underscores the market’s anxiety over execution risks and sector-wide supply constraints.

Quebrada Blanca Operational Setbacks and Merger Volatility Drive Sharp Decline
Teck’s 4.69% drop is a direct consequence of two interlinked factors: persistent operational delays at its Quebrada Blanca (QB) mine in Chile and regulatory uncertainty surrounding its merger with Anglo American. The company slashed 2025 copper production guidance by 19% to 170K–190K tonnes due to tailings storage issues, equipment failures, and pit instability at QB. Simultaneously, the $53B merger faces Canadian regulatory hurdles under the Investment Canada Act, with Anglo American’s 62.4% ownership stake in the combined entity raising concerns about national interest alignment. These dual pressures have triggered profit-taking and speculative shorting, exacerbated by broader copper market volatility from Freeport-McMoRan’s Grasberg mine disaster and Chinese smelter activity moderation.

Copper Sector Volatility Intensifies as Freeport-McMoRan Leads Downward Slide
The copper sector is in turmoil, with Freeport-McMoRan (FCX) down 3.93% on the same day as Teck’s selloff. FCX’s Grasberg mine, the world’s second-largest copper operation, remains offline after a deadly mudslide, removing 591K tonnes of annual production. This aligns with Teck’s production cut, creating a perfect storm of supply disruptions. While Teck’s 4.69% drop is merger-specific, the sector-wide selloff reflects broader fears of a 2026 supply deficit. BHP’s $840M Olympic Dam expansion and Cyprium’s WA copper restart are positive counterpoints, but they lack the scale to offset current outages.

Backtest Teck Resources Stock Performance
Key findings 1. Since January-2022 there were 33 sessions in which TECK fell 5 % (or more) from the open to the intraday low. 2. A 30-day event study shows that, on average, TECK recovers modestly after such plunges: cumulative excess return ≈ +6 % by trading-day 30, but the pattern is not statistically significant at conventional levels. 3. Win-rate turns positive quickly (≈ 70 % by day 2) and remains near 60-70 % through day 30, indicating a mild positive drift rather than a sharp v-shaped rebound. 4. No meaningful edge is observed in the first 1-3 days; the incremental advantage appears only after the first week.

Urgent Action Required: TECK’s Merger and Production Risks Demand Tactical Precision
Teck’s 4.69% drop is a warning shot for investors navigating the volatile copper sector. The merger’s regulatory hurdles and QB mine delays are immediate catalysts, but the broader supply deficit and Chinese smelter moderation could prolong the selloff. Watch the 41.74 support level and the 38.67 long-term support for directional clues. Freeport-McMoRan’s -3.93% decline underscores sector-wide fragility. For now, short-term traders should prioritize options like TECK20251017C42.5 for bearish exposure, while long-term investors must monitor the Investment Canada Act review and Anglo American’s $4.5B special dividend. Action: If 41.74 breaks, consider TECK20251024C40 for a 40.00 pivot.
