PCG's 48% Volume Surge Drives 303rd Rank Amid Market Volatility

On September 26, 2025, Pacific Gas & Electric (PCG) traded at a volume of $350 million, representing a 48.41% surge from the previous day’s activity. This ranked the stock 303rd among all traded securities in terms of daily volume, marking a notable increase in market engagement for the utility sector player. The stock closed with a 3.67% gain, driven by heightened trading interest amid broader market volatility.

Recent developments suggest renewed institutional focus on PCG, with analysts noting elevated order flow consistent with large-cap value rotation patterns. While no material earnings or regulatory updates were disclosed, the volume spike aligns with historical tendencies where utility stocks attract capital during macroeconomic uncertainty. Short-term technical indicators show the stock testing key resistance levels, though sustained momentum remains contingent on follow-through buying.

To run this back-test robustly I need to nail down a couple of practical details: 1. Universe definition • Do you want to consider all primary-listed U.S. common stocks (NYSE + NASDAQ) each day, or a specific universe (e.g., the Russell 3000, S&P 500 constituents, etc.)? • Is ADR / ETF / preferred-share volume to be excluded? 2. Volume ranking metric • Shares-traded volume (default) or dollar volume? 3. Trade timing • Buy at today’s close and sell at tomorrow’s close (T+1)? • Or buy at tomorrow’s open and sell at tomorrow’s close? 4. Portfolio construction • Equal-weight the 500 names each day (standard approach) or weight by volume / market-cap / something else? 5. Slippage & transaction costs • Apply zero costs (default) or add an explicit per-trade cost? Once I have these points I can generate the daily trading signals, run the one-day-holding-period back-test from 2022-01-03 (first trading day of 2022) through the present, and deliver performance statistics and an interactive visualization. Let me know your preferences and I’ll proceed.
