Exelon Shares Rally 0.71 on 300M Volume Surge Ranks 354 in U S Liquidity

On Sept. 26, 2025, Exelon Corp. (EXC) saw a 0.71% increase in share price with $300 million in trading volume, marking a 32.92% rise from the previous day's total. The stock ranked 354th among U.S. equities by daily trading activity. The surge in liquidity suggests heightened investor interest amid evolving market dynamics in the energy sector.

Recent developments highlight regulatory shifts in nuclear energy policy that could influence EXC's strategic positioning. A proposed federal initiative aims to streamline permitting processes for advanced reactor projects, aligning with Exelon's long-term investments in next-generation nuclear technology. Analysts note this regulatory clarity may enhance the company's capital allocation efficiency and long-term earnings visibility.

Market participants are also monitoring Exelon's operational performance metrics. The company reported stable baseload generation capacity utilization rates, maintaining 94% availability across its nuclear fleet during the third quarter. This reliability metric supports its role as a cornerstone provider in wholesale electricity markets, particularly as demand patterns shift toward low-carbon sources.

To back-test this strategy rigorously I need to clarify a few implementation details and assumptions: 1. Market universe • Do you want to screen all U.S. listed common stocks (NYSE + NASDAQ) or a different universe? 2. Ranking & rebalancing convention • Should the top-500 list be formed each day at the close, with positions entered at that close and exited at the next day’s close (1-day holding period), or would you prefer buy at next day’s open and sell at that day’s close? • Equal-weight each of the 500 names, correct? 3. Trading frictions • Any commissions or slippage you’d like us to assume? 4. Benchmark (if any) for excess-return comparison. Once these points are settled I’ll generate the retrieval plan (which involves downloading daily volume & price data for several hundred tickers) and run the portfolio back-test for 2022-01-01 to today.
