Sempra Energy Shares Rally on Regulatory Shifts as $440M Volume Ranks 259th in U.S.

On October 7, 2025, Sempra Energy (SRE) saw a 1.68% rise in share price, with trading volume surging to $440 million—a 68.09% increase from the previous day—ranking it 259th among U.S. stocks by volume. The move followed mixed regulatory developments in its core infrastructure markets.

Recent news highlighted evolving dynamics in California’s energy policy framework. A state senate committee advanced legislation to accelerate decarbonization timelines for gas utilities, which could impact Sempra’s regulated gas distribution operations. Separately, a federal appeals court upheld a key permitting decision for the company’s liquefied natural gas export terminal project in Louisiana, removing a potential near-term headwind for capital deployment in high-margin infrastructure assets.

Analysts noted the stock’s performance reflected investor parsing of regulatory risks versus long-term growth catalysts. While decarbonization policies may pressure short-term earnings from gas operations, the court ruling on the Louisiana terminal reinforced confidence in Sempra’s ability to execute large-scale energy transition projects. The company’s dual business model—combining regulated utilities with growth-oriented infrastructure—remains central to its valuation narrative.

To run this back-test rigorously I need to pin down a few practical details: 1. Market universe • Do you want to screen all listed U.S. stocks (NYSE + NASDAQ + AMEX), or a different universe? 2. Rebalancing mechanics • Each day we form an equally-weighted basket of the 500 highest-volume names at that day’s close, then hold for exactly one trading day (sell at next-day close). • Is equal weight acceptable, or would you prefer volume-weighted or another scheme? 3. Trading-cost assumptions • Should we include transaction costs or slippage? If so, at what rate (e.g. 10 bps round-trip)? 4. Benchmark (optional) • Would you like the results compared with a benchmark such as the S&P 500? Once I have these four items confirmed I can generate the signals and run the back-test from 2022-01-03 through today.
