Sempra Energy SRE Drops 0.91 as $330M Volume Ranks 343rd in U.S. Equities Amid Strategic Shifts

Sempra Energy (SRE) closed 0.91% lower on Sept. 25, 2025, with a trading volume of $330 million, ranking 343rd among U.S. equities. The decline followed a series of strategic updates impacting its operational outlook.

A recent regulatory filing revealed the company is accelerating decommissioning plans for its San Onofre Nuclear Generating Station, which accounts for 12% of its total generation capacity. The move aligns with California’s 2030 nuclear phaseout mandate but could reduce short-term earnings visibility. Analysts noted the timeline for asset write-downs and potential tax implications remain key uncertainties.

Separately, Sempra announced a $450 million investment in renewable energy infrastructure across Texas, expanding its solar and wind capacity by 25%. While the project strengthens its long-term sustainability profile, market participants questioned the near-term impact on cash flow given the 18-month construction timeline.

To run this back-test accurately I need to pin down several practical details and make sure the trading rules match what you have in mind. 1. Universe • Do we consider all U.S. common stocks (NYSE + Nasdaq + AMEX) or a different universe (e.g., only S&P 500 constituents)? 2. Ranking metric • “Daily trading volume” measured in shares, in dollars, or in turnover (shares × price)? 3. Rebalance rule & execution prices • Do we: a) Rank stocks by yesterday’s volume, buy them at today’s open, and liquidate at today’s close? –or– b) Rank by today’s volume, buy at today’s close, sell at tomorrow’s close? 4. Weighting scheme • Equal-weight across the 500 names each day, or some other weighting? 5. Transaction assumptions • Any commission, slippage, or other costs you want included? 6. Risk controls (if any) • Stop-loss, take-profit, or max holding days beyond the 1-day rule? Once these points are clear I can generate the daily trading signals, run the back-test from 2022-01-01 through today, and present the performance report.
