Exelon Shares Climb 0.82% Amid 58% Volume Plunge to 498th Rank as Merger Whispers Keep Stock in Speculative Spotlight

Exelon Corp. (EXC) closed higher by 0.82% on Oct. 3, 2025, with a trading volume of $220 million, marking a 58.06% decline from the previous day’s volume. The stock ranked 498th in terms of trading activity across the U.S. equity market, reflecting mixed institutional interest amid sector-specific dynamics.

Recent developments suggest shifting investor sentiment toward utility stocks, with Exelon’s performance influenced by broader market rotations into energy infrastructure plays. Analysts noted that regulatory clarity on emissions standards and grid modernization funding could drive renewed demand for utility equities, though near-term volatility remains tied to macroeconomic signals.

A pending merger evaluation involving Exelon and a regional energy provider has drawn limited public commentary, with no material updates disclosed in recent filings. However, whispers of strategic asset reallocation within the sector have kept the stock in speculative focus, despite subdued volume levels.

To run this back-test accurately we’d need daily market-wide data so we can (1) rank every listed stock by that day’s share-trading volume, (2) assemble an equal-weighted basket of the top 500 names, and (3) roll the basket forward one day. Our current tool-set supports single-ticker signals and event studies, but it does not (yet) provide a direct “market-wide ranking” function. We have two practical ways to proceed: 1. Static proxy list • Create a fixed list of 500 stocks that consistently trade at the highest volumes (e.g., based on 2024-25 averages), and back-test the one-day hold strategy on that static universe. • This is simpler to implement but only approximates the rolling “top-volume” idea. 2. Custom dataset (requires upload) • If you can provide, or are willing to let me fetch, a daily file that already contains the top-500-by-volume symbols for each date (or the full daily volumes for all stocks), I can import that list and run the exact one-day basket back-test.
