Seasonality Charts

Seasonality Charts

Our Interactive Seasonality Chart lets you interactively determine how frequently a stock rises during each month of the year.

The idea is that certain stocks perform better during particular months of the year. This tool will allow you to confirm whether or not those kind of “seasonal” effects happen for any ticker symbol in our database.

In the example above, each histogram bar represents a different month of the year. The height of each bar is determined by the percentage of years that the stock ($SPX in this case) has risen during that month. The number at the bottom of each column is the average gain/loss for that month. The slider at the bottom of the chart lets you change the chart's timeframe. In addition to “Histogram” mode, there are two other modes for viewing the underlying data - “Separate Scales” and “Same Scale.” Here's what they look like:

Separate Scales:

Same Scale:

Working With Interactive Seasonality Charts

Changing the Chart's Time Period

You can use the slider at the bottom of the chart (#3 in the image above) to change the chart's starting and/or ending years.

You can use your mouse to adjust the slider in the following ways:

  • You can click on the middle of the slider's thumb and drag it left or right to change both the starting year and ending year. This allows you to “slide” your chart forward and backwards through time.
  • You can click on the left edge of the slider's thumb and drag it left or right to change the chart's starting year.
  • You can click on the right edge of the slider's thumb and drag it left or right to change the chart's ending year.

There are several keyboard equivalents that you can also use to adjust the chart's start and end dates:

  • You can use the left and right arrow keys to move the entire slider's thumb left and/or right.
  • You can hold down the Shift key and then use the left and right arrow keys to change the chart's starting year.
  • You can hold down the Control key (Cmd on a Mac) and then use the left and right arrow keys to change the chart's ending year.

Note: You may need to click once on the Seasonality Chart before the keyboard controls will work.

Turning Years On and Off

Click any of the year buttons above the chart (#2 in the image above) to hide that year's line and remove that year's data from the calculations. Click on the button again to return it to the chart.

Creating a "Comparison" Seasonality Chart

Enter a ticker symbol into the optional “Compare” box and press “Go” to show how frequently the chart's main symbol outperforms the Comparison symbol.

Separate Mode vs. Same Scale Mode vs. Histogram Mode

Three buttons in the lower left corner of the chart (#4 in the image above) allow you to switch between “Separate Mode,” “Same Scale Mode” and “Histogram Mode” (the default).

Resizing the Chart

You can click and drag the lower right corner of the chart to resize the chart inside your browser window.
