DTE Energy Surges on 91.5% Volume Spike Ranks 446th as Institutional Investors Build Strategic Positions

DTE Energy (DTE) closed with a 0.52% gain on October 3, 2025, as trading volume surged to $0.24 billion—a 91.5% increase from the previous day—ranking it 446th in market activity. The uptick in liquidity suggests heightened investor interest in the utility sector ahead of potential earnings announcements or regulatory updates in the coming week.

Analysts noted the volume anomaly as a potential indicator of strategic position-building by institutional investors, though no material corporate actions were disclosed in the preceding 72 hours. The stock’s performance diverged from broader market trends, with its relative strength index showing no signs of overextension, suggesting the rally remains within a balanced technical framework.

To run this back-test robustly I need to confirm a few practical details so I can set the tool parameters correctly: 1. Market universe • Are we talking about all U.S. listed common stocks (NYSE + NASDAQ), or a different market? 2. Trade timing • Do you want to rank stocks on the same-day volume, buy them at that day’s close, and exit at the next day’s close (i.e., holding for one full trading day)? • Or would you prefer to rank on the prior day’s volume, buy at the next day’s open, and exit at that day’s close? 3. Portfolio construction • Equal-weight across the 500 names each day, or another weighting scheme? 4. Frictions • Should we ignore transaction costs and slippage for now (default), or incorporate an assumed cost? Once I have these points I can set up the batch data pull and run the back-test.
