Mastercards Price Surges 0.62% as Trading Volume Slumps to 1.43 Billion Ranking 64th in Liquidity

On October 2, 2025, Mastercard (MA) closed with a 0.62% gain, while its trading volume fell to $1.43 billion, marking a 32.16% decline from the previous day and ranking 64th among stocks in terms of liquidity. The mixed performance reflects shifting investor sentiment amid evolving market conditions.

The subdued volume suggests reduced short-term speculative activity, potentially linked to broader market volatility or sector-specific adjustments. However, the modest price increase indicates underlying confidence in the payment giant’s long-term positioning, particularly as transaction volumes stabilize in key markets. Analysts note that macroeconomic signals and regulatory developments remain critical variables for near-term momentum.

To perform this back-test accurately I need to clarify a couple of points: 1. Market universe • Are we ranking only U.S.-listed equities (e.g., all common stocks on NYSE + NASDAQ), or another market? • If it’s a specific index universe (e.g., S&P 500 constituents) please confirm. 2. Portfolio implementation • The back-testing engine can track one ticker at a time. For a multi-stock strategy we usually simulate the daily portfolio return by creating an index/ETF proxy or by computing the aggregated daily P&L externally and then feeding that series into the engine. • Would you like to approximate the “top-500-by-volume” basket with a readily tradable ETF (e.g., SPY) or would you prefer us to build an equal-weighted synthetic portfolio? Let me know your preference and I’ll proceed with the appropriate data pull and back-test setup.
