Comerica's 13.68% Surge Driven by 1,854.6% Volume Spike Ranks 46th in Dollar Volume Among U.S. Stocks

Comerica Inc. (CMC) surged 13.68% on October 6, 2025, with a trading volume of $1.88 billion—a 1,854.6% increase from the prior day—ranking it 46th in dollar volume among U.S. equities. The spike followed renewed investor focus on regional banking stocks amid shifting macroeconomic signals and sector-specific catalysts.

Analysts noted that Comerica’s performance aligned with broader trends in financial services, driven by expectations of tighter credit conditions and potential regulatory tailwinds. The stock’s elevated volume suggested short-term speculative activity, though fundamentals remain tied to regional economic health and loan portfolio dynamics. No direct earnings or earnings guidance updates were cited in the period’s coverage.

To construct an accurate back-test, the following parameters require clarification: (1) the universe of stocks (e.g., all U.S. listed equities or S&P 1500 constituents); (2) trade execution timing (e.g., closing vs. opening prices); (3) weighting methodology (equal weight vs. dollar-volume or market-cap weighted); and (4) cost inclusion (transaction fees, bid-ask spreads). These variables will determine the robustness of the 2022–present performance analysis. Once finalized, the data can be processed to evaluate the strategy’s historical viability.
