Iamgold Surges 1.03% on $300M Volume Spurt Ranks 372nd in Market Activity

Iamgold (IAG) surged 1.03% on Sept. 25, with a trading volume of $0.30 billion—up 111.28% from the previous day—ranking 372nd in market activity. The move followed renewed focus on the gold sector amid shifting macroeconomic signals and operational updates from the miner.

Analysts highlighted mixed catalysts influencing the stock. A recent production update noted stable output from its Canadian and Brazilian operations, while ongoing exploration efforts in Colombia added speculative traction. However, the firm reiterated its cautious stance on near-term capital expenditures, aligning with industry trends of cost discipline amid volatile commodity prices. These factors contributed to a balanced investor response, with technical indicators showing short-term momentum amid broader market uncertainty.

To execute this back-test accurately we need to pin down a few practical details: 1. Market universe • Do you want all U.S.-listed common stocks (≈ 4 000 names) ranked each day by dollar trading volume? • Or a specific universe (e.g., only S&P 500 constituents, only Nasdaq, only NYSE, etc.)? 2. Portfolio construction and execution • Weighting: equal-weight across the 500 names each day? (Typical for this type of “top-N” volume strategy.) • Entry/exit prices: buy at the close of day t (after volume data are known) and sell at the next day’s close (holding period = 1 trading day)? • Transaction costs/slippage to include? (If you have no preference I can apply a standard 0.10% round-trip cost.) 3. Data availability / tool support Our automated back-test engine can process one ticker (or index) at a time, so to implement a true 500-stock daily-rebalanced portfolio we’ll create an equal-weighted composite “virtual ticker” built from the underlying constituents. That requires the clarifications above.
