Which Months Are Best (and Worst) for the Stocks You Trade?
The Seasonality tool displays historical monthly return patterns for any stock or ETF, including both the median and average performance for each calendar month over multiple years.
Many traders observe that certain months or periods tend to be stronger or weaker than others for specific securities. While anecdotal observations such as weak September performance or strength in November are common, these patterns are often discussed without being systematically measured against the actual historical data for the instruments being traded.
This tool provides a structured view of seasonal tendencies by quantifying average and median returns by month, helping traders evaluate whether observed patterns hold up when examined across a stock or ETF's full history.
Displays a bar chart of average or median returns for each calendar month, with positive months shown in green and negative months in red for quick visual interpretation.
Provides a detailed heatmap where each row represents a year and each column represents a month. The color scale (green to red) shows performance, along with yearly totals to help assess consistency over time.
Allows you to switch between median and average returns in both the bar chart and heatmap views. This helps distinguish between typical performance and results that may be skewed by outliers.
Offers a broad view that displays seasonality across an entire watchlist. This makes it easy to compare seasonal profiles across multiple names at once.
Select a ticker to see which months have historically delivered stronger or weaker average and median returns. This provides a high-level view of potential seasonal biases.
Use the year-by-month heatmap to evaluate whether a month's historical edge has been consistent over time or driven primarily by one or two outlier years.
When planning a monthly holding period, check whether the relevant months have historically been favorable or unfavorable for the stock. This helps set more realistic expectations for the trade.
Review seasonal profiles across a watchlist or group of tickers to identify which securities have the most favorable historical patterns for the current season.
