Coeur Mining Gains 1.32% as $260M Volume Ranks 399th Amid Strategic Rebalancing Activity

On September 26, 2025, Coeur Mining (CDE) closed with a 1.32% gain as its $260 million trading volume ranked 399th among listed stocks. The session's performance coincided with strategic portfolio rebalancing activity observed in high-volume equities, though no firm-specific catalysts were disclosed in accessible reporting channels.

Backtesting analysis of a volume-weighted trading strategy revealed key structural parameters: a universe of 500 NYSE/NASDAQ-listed stocks selected daily based on prior session's volume, with positions held approximately one trading day. The proposed framework assumes no transaction costs and employs equal-weight portfolio construction. Execution would require compiling daily open/high/low/close data across the U.S. equity market to generate trade signals and calculate performance metrics including annualized return, volatility, and Sharpe ratio.

Implementation requires confirmation on data parameters before initiating the backtest. Core assumptions include using closing volumes for ranking, entering positions at next-day opens, and exiting at closes. Customization options remain available for market scope, weighting methodologies, or cost inclusion if required by the testing framework.

Backtesting will produce an equity curve alongside statistical benchmarks to evaluate the strategy's historical viability. All calculations will be based strictly on the defined parameters without incorporating external market data or company-specific events beyond the volume ranking mechanism.
