Does the time of year matter?

Seasonality shows how a market has usually behaved in each part of the calendar, and how often that held. Here is one frozen example: the S&P 500 ETF (SPY), month by month, over 15 years. Tap a month.

Frozen example: SPY, 2011 to 2025, as of October 29, 2026

An average can hide a lot. A month can average a gain because of one big year, so the tool always shows how many years were up and grades how sure the pattern is. "Inconclusive" is the most common grade, and it is the honest one.

Members can look up a wide range of stocks, ETFs, futures and currencies, see the day-by-day curve with this year drawn on top, and check whether a pattern held up in years it was not built on.
