C Stock’s $0.23B Volume Secures 459th Intraday Ranking

On September 26, 2025, C posted a trading volume of $0.23 billion, securing the 459th position in intraday trading activity. The stock’s liquidity profile remains constrained compared to broader market benchmarks, reflecting limited institutional participation and retail investor engagement.

Designing a back-test for a “Top-500-by-volume” rotation strategy requires clarification on several parameters. The market universe must specify whether U.S.-listed stocks (NYSE/NASDAQ) are targeted, or if over-the-counter (OTC) and American Depositary Receipts (ADRs) are included. Practical implementation demands a predefined list of tickers, as dynamic daily screening exceeds platform capabilities. Two common approaches include restricting the universe to S&P 500 constituents or using an ETF proxy for high-liquidity exposure. Trade mechanics, such as entry/exit timing (e.g., close-to-close) and equal-weighting assumptions, also require confirmation. Transaction cost assumptions—whether zero or estimated—must align with the test’s feasibility.
