Teck Resources Surges Into Top 274 Traded Stocks on 119.72% Volume Spike

On October 8, 2025, Teck Resources (TECK) saw a surge in trading activity with a volume of $0.42 billion, marking a 119.72% increase from the previous day. The stock closed up 1.44%, securing a position in the top 274 most traded equities nationwide. This liquidity spike suggests heightened investor interest, potentially driven by sector-specific developments or strategic updates from the company.

Recent market activity highlights Teck’s exposure to global commodities dynamics. Analysts note that shifting demand patterns in critical minerals and metallurgical coal markets have directly influenced the stock’s trajectory. The company’s diversified portfolio across energy, steelmaking coal, and copper has positioned it to benefit from near-term industrial demand cycles, though long-term volatility remains tied to macroeconomic signals such as interest rates and trade policy shifts.

To build an accurate back-test I need to confirm a few practical details about the trading rule and the investment universe: 1. Universe • Should the “top-500 by volume” be selected from all U.S. common stocks (≈7,000 tickers) or from a narrower set (e.g., Russell 3000, S&P 1500, NASDAQ-listed only, etc.)? • Do we include ETFs or restrict to single-name equities? 2. Execution convention • Entry: Buy the 500 stocks at today’s close or tomorrow’s open? • Exit: Sell at the next day’s close or next day’s open? (The usual practice is “buy at today’s close, sell at tomorrow’s close,” but please confirm.) 3. Weighting & rebalancing • Equal-weight each position daily, or weight by (for example) inverse volatility, market-cap, etc.? • Rebalance every trading day (i.e., fully refresh the 500 names each day)? 4. Costs & slippage • Assume zero transaction costs and slippage, or apply a per-trade commission/impact estimate? 5. Benchmark / performance metrics • Any particular benchmark to show (e.g., SPY), or just raw strategy return? With these points clarified I can generate the daily trade lists, run the back-test from 2022-01-03 (first trading day in 2022) through today, and report the statistics and equity curve.
