Mastercard Slides 0.20% as $1.63B Volume Crumbles to 49th in U.S. Rankings

On Sept. 24, 2025, Mastercard (MA) closed down 0.20% with a trading volume of $1.63 billion, ranking 49th in dollar volume among U.S.-listed stocks. The decline came amid mixed signals from regulatory developments and broader market volatility.

Recent regulatory scrutiny over payment network fees intensified as lawmakers in key markets proposed revised interchange rate frameworks. While Mastercard has historically benefited from higher transaction costs, potential reforms could pressure long-term margins. Meanwhile, the company's Q3 earnings guidance remained in line with expectations, with no material revisions to its digital commerce growth projections.

Market participants also noted reduced short-term liquidity in the sector following the expiration of several derivative contracts tied to payment processors. Analysts observed that the stock's intraday performance correlated closely with broader financial indices, suggesting macroeconomic factors played a more significant role than company-specific news on Wednesday.

To run this study rigorously I need to know a few practical details up-front and make sure the requested test is feasible with our current tooling: 1. Market universe • Should we limit ourselves to US-listed common stocks (NYSE + Nasdaq), or do you want a different universe? • Any filters on ADRs, ETFs, penny stocks, etc.? 2. Exact trading rule • Daily ranking is based on the previous day’s dollar volume or share volume? • Entry price: open of the next session, or close of the ranking day? • Exit price: close of the same day you enter (i.e., 1-day hold), or the next day’s open? 3. Weighting scheme • Equal-weight across the 500 names, or volume-weighted / dollar-weighted? 4. Practical consideration • Our built-in back-test engine is designed for one security at a time. For a cross-sectional strategy like this, we can still implement it, but we need to batch-process thousands of tickers and aggregate the results. That is computationally heavier and may require trimming the period or universe (e.g., S&P 1500, Russell 3000, etc.) to stay within resource limits. Once we settle those details I’ll translate the strategy into the required signals, pull the necessary data, and run the portfolio-level back-test for 2022-01-01 through today. Let me know your preferences on the above so we can proceed.
