What is PSX stock seasonality?
Stock seasonality is the tendency of a stock to perform in a similar way during the same period each year. By analysing Phillips 66's price history across many years, SeasonalityX identifies recurring calendar windows — exact start and end dates — where PSX has repeatedly risen (bullish) or fallen (bearish). Each pattern is scored by its win rate and average return so you can judge how reliable and how strong it has been.
