- Endeavour Silver (EXK) surged 6.85% on $290M volume, ranking 397th in market activity after consolidation.

On October 8, 2025,

(EXK) surged 6.85% with a trading volume of $0.29 billion, marking a 45.31% increase from the previous day. The stock ranked 397th in trading activity across the market, indicating renewed short-term institutional interest following a period of consolidation.

Analysts noted elevated open interest in options contracts ahead of the earnings window, though no material operational updates were disclosed in the latest filings. The volume spike coincided with broader silver price volatility but lacked direct catalysts such as production guidance or capital allocation announcements. Market participants remain cautious about near-term price sustainability amid mixed technical indicators.

Regarding the proposed backtest framework: The strategy involves daily ranking of U.S.-listed equities by dollar volume, constructing an equal-weighted portfolio of the top 500 names, and holding positions for one trading day. Implementation requires resolving practical details including market scope (NYSE/NASDAQ), entry/exit timing (close-to-close or open-to-close), and transaction cost assumptions. While the current engine supports single-ticker analysis, aggregating returns for a 500-stock basket necessitates external data processing. Confirmation on these parameters is required to initiate the backtest, which will evaluate performance metrics and equity curve evolution from January 1, 2022, to the present.
