Phillips 66 Stock Slides 1.43% Amid Maintenance-Driven Capacity Adjustments and Biofuel Expansion Ranked 408th in Daily Trading Volume

On October 3, 2025, Phillips 66 (PSX) closed with a 1.43% decline, trading with a daily volume of $270 million, ranking 408th in market activity. The stock’s performance reflects mixed signals from operational updates and broader market dynamics.

Recent reports highlighted adjustments in the company’s refining capacity utilization, with Q3 maintenance schedules temporarily reducing throughput at key U.S. Gulf Coast facilities. Analysts noted this could delay near-term earnings visibility but emphasized long-term resilience in its downstream energy infrastructure. No major regulatory or partnership developments were disclosed during the period.

Strategic shifts in the company’s renewable fuels division also drew attention, as it announced a phased expansion of biofuel blending capabilities. While the move aligns with decarbonization trends, execution risks remain tied to feedstock availability and federal policy uncertainties. Market participants remain cautious ahead of the fourth-quarter earnings release.

To run this back-test accurately I need a bit more detail about the investment universe and a few practical assumptions: 1. Universe • Should I consider every U.S.‐listed common stock (NYSE + NASDAQ + AMEX), or a narrower set such as the current S&P 1500 / Russell 3000 constituents? 2. Weighting method • Equal-weight each of the 500 names, or weight them by dollar volume / market-cap, etc.? 3. Transaction costs & slippage • Assume zero costs, or include an estimate (e.g., 5 bp each side)? 4. Data frequency • Use official daily close volume and next-day open/close prices for entry/exit? 5. Rebalancing mechanics • Open at today’s close and liquidate at tomorrow’s close (1 trading-day hold), or open at next-day open and liquidate at next-day close? Once I have these details I can pull the necessary data, construct the daily top-500 basket, and run the strategy back-test from 2022-01-03 to the present.
