CME Climbs to 180th in Volume Ranking with 43.48% Trading Surge as Shares Rise 0.51%

On October 8, 2025, Chicago Mercantile Exchange (CME) reported a trading volume of $0.61 billion, marking a 43.48% increase from the previous day and ranking 180th in volume among all stocks. The exchange’s shares closed with a 0.51% gain, reflecting heightened market engagement amid a broader sector-wide rebound.

The surge in volume suggests renewed institutional or algorithmic interest in CME’s market infrastructure, potentially linked to evolving demand for derivatives trading platforms. While no direct earnings or regulatory updates were cited, the price action aligns with a defensive shift in capital toward established financial exchanges as macroeconomic volatility persists.

To set up this back-test accurately I need a few extra details: 1. Universe: Which market should the “top-500-by-volume” list be drawn from (e.g., all U.S. listed equities, only S&P 500 constituents, another exchange)? 2. Execution convention: Should we rank stocks on each day’s close, buy at that same close and exit at the next-day close, or rank on the day’s close, buy at the next-day open and sell at the next-day close, or another convention? 3. Transaction costs / slippage: Do you want to include any (e.g., 2 bps per side), or assume frictionless trading? Once I have this information I can proceed with the back-test setup.
