What is FDS stock seasonality?
Stock seasonality is the tendency of a stock to perform in a similar way during the same period each year. By analysing FactSet's price history across many years, SeasonalityX identifies recurring calendar windows — exact start and end dates — where FDS 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.
Seasonality is one input among many — it works best alongside your own research and risk management. Learn more in our guide to seasonal analysis and the tutorials.
