Teck Resources Surges 3.6% on 89% Volume Spike, Ranks 246th in North America

On September 24, 2025, Teck Resources (TECK) surged 3.60% to close at $27.85, outperforming broader market benchmarks. The stock’s trading volume spiked to $420 million, a 89.29% increase from the prior session, ranking it 246th among the most actively traded equities in North America. This surge coincided with renewed investor focus on commodities sector dynamics amid shifting macroeconomic expectations.

Analysts attributed the rally to a combination of technical factors and evolving risk appetite. A key catalyst appeared to be a shift in positioning among institutional investors, as volume expansion suggested increased participation from long-only funds. The stock’s performance diverged from recent trends, where volatility had been constrained by cautious positioning ahead of quarterly earnings reports. While no company-specific announcements directly influenced the move, broader sentiment in base metals markets showed signs of stabilization, potentially attracting capital rotation into cyclical assets.

To build and back-test this “top-volume” strategy accurately, I’ll need to pin down a few practical details: Universe • Do you want to screen all U.S. listed common stocks (≈5,000 names), only the Russell 3000, the S&P 500, or another universe? Entry & exit prices • Should we buy at the same day’s close and exit at the next day’s close? • Or buy at the next day’s open and exit at the same day’s close? (The answer affects both slippage assumptions and the set of tradable tickers each day.) Transaction costs / slippage • Should we assume zero cost, a fixed commission, or a bid-ask spread (e.g., 5 bp per side)? Rebalancing logistics • Equal-weight all 500 names every day (classic “top-N” style)? • Or weight by dollar volume / market cap? Delisting / survivorship bias handling • OK to include only securities that are still active today, or should we use a point-in-time listing set to avoid bias?
