Phillips 66 (PSX) closed at $269.74 on October 6, 2026, marking a 1.93% gain for the session. The move added to an already notable stretch of performance for the Houston-based energy company.
Over the past seven days, PSX has advanced 6.37%, while the trailing 30-day period shows a gain of 5.74%. The consistency of gains across all three timeframes points to sustained buying interest in the stock.
Phillips 66 carries a market capitalization of $105.57 billion, reflecting its standing as one of the larger publicly traded refining and midstream energy companies. The stock's price action over the past month suggests continued investor attention to the name.
With the 30-day and 7-day gains both in positive territory and the single-session move reinforcing that trend, PSX has demonstrated notable momentum heading into the remainder of the trading week.
