Relative Rotation Graph (RRG) Charts

Relative Rotation Graph (RRG) Charts

Relative Rotation Graphs (“RRG charts”) show you a security's relative strength and momentum relative to a collection of other securities. RRG charts were developed by Julius de Kempenaer and have been available on Bloomberg terminals since 2011.

Note: Both “Relative Rotation Graph™” and “RRG™” are registered trademarks of RRG Research.

RRG charts differ from most other financial charts in that the horizontal axis does not represent time. An RRG chart is a scatter plot with Julius' Relative Strength Ratio indicator as the horizontal axis and his Relative Strength Momentum indicator as the vertical axis.

Here's an example of an RRG chart:

Note that each symbol on an RRG chart is plotted as a dot with a “tail” extending backwards. The tail shows you the history of the symbol's position in the past. You can use a slider to control the length of the tail.

Each dot on each symbol's tail represents one period - either one week or one day depending on the “Period” setting. The large dot at the end of the tail represents the current RRG values for that ticker symbol. Those values are updated continually throughout the current trading week; however, new dots are only added at the start of a new week.

Also note that there are four quadrants on the chart:

  • Leading (Green) - strong relative strength and strong momentum
  • Weakening (Yellow) - strong relative strength but weakening momentum
  • Lagging (Red) - weak relative strength and weak momentum
  • Improving (Blue) - weak relative strength but improving momentum

As you can see in the example above, stocks typically progress through the quadrants in a clockwise manner.

The color of each line is determined by the color of the quadrant where the line ends. The width of each line is determined by the ending dot's distance from the center of the plot.

For more on interpreting RRG charts, please see our ChartSchool article on the topic. You can also read more about RRG charts in Julius de Kempenaer's blog.

Free RRG Features vs Member-only RRG Features

Free users are only able to see a single, fixed RRG chart that consists of the major North American market averages with 3 years of data. Free users can change the chart's ending date, trail length, and scaling, but they are not able to add/remove ticker symbols, view longer range data, or resize the chart.

Members can also create RRG charts from their ChartLists. These RRG charts are limited, however, to the first 50 ticker symbols on the ChartList.

Creating RRG Charts

There are several ways to create an RRG chart, including:

  • Click on the “Free Charts” tab at the top of any page, then click on the “Launch RRG Chart” link in the Relative Rotation Graphs section.
  • Click on the “RRG Charts” link on the right side of the home page in the “Charting Tools” area.

Members can use the text box at the top of the RRG tool to change the list of symbols used in the chart. Or they can select from one of several predefined symbol groups using the “Groups” dropdown. Up to 50 different ticker symbols can be charted on an RRG chart.

Members can also change the RRG chart's “Benchmark” symbol - the symbol (typically an index like $SPX) that is used in the relative performance calculations. A line chart of the benchmark symbol is always displayed to the right of the RRG chart.

Elements of the RRG Chart Tool

The RRG Chart Tool has several different elements:

  1. The RRG Plot
  2. The “Benchmark” Chart (typically the S&P 500)
  3. The “Tail Length” Slider
  4. The Scaling Control Buttons
  5. The Symbols Table
  6. The Symbols Box (members-only)
  7. The Benchmark Box (members-only)
  8. The Groups Dropdown (members-only)
  9. The Years Dropdown (members-only)
  10. The Update Button (members-only)
  11. The Maximize icon (members-only)
  12. The Resize icon (members-only)
  13. The “Linkable Version” link (members-only)

Modifying an RRG Chart

Changing the Chart's Ending Date

Next to the RRG chart is a smaller chart of the benchmark symbol (typically $SPX, the S&P 500 Large Cap index). You can click anywhere on that graph to change the ending date for the RRG plot. The benchmark chart is meant to give you a sense of what the market as a whole was doing at the time of the RRG plot. In addition to clicking on the benchmark chart, you can also click and drag to manually animate things.

In addition, you can use the left and right arrow keys on your keyboard to change the ending date.

You can also press the “animate” button below the benchmark chart to automatically move the RRG plot through all the available data.

Changing the Tail Length

You can use the “Tail Length” slider below the benchmark chart to adjust the length of the tails on the RRG plot. The zone highlighted in blue on the benchmark chart shows the period of time covered by the tails.

Highlighting Individual RRG Lines

You can click on any of the lines in the Symbol Table below the RRG Plot to turn on highlighting for that symbol. Click on the line again to turn off highlighting. Only one line at a time can be highlighted.

Changing the Graph's Scaling

You can use the buttons below the benchmark chart to adjust the RRG plot's scaling.

  • + and Allow you to manually zoom the RRG plot in and out
  • fit - Automatically adjusts the vertical scales so that all RRG lines are always visible
  • ctr - Enables a mode that ensures that all RRG lines are always visible. It also centers the origin of the chart. Very useful with the animate option.
  • max - Expands the vertical scales to the maximum size needed to see every RRG line at any point in time.

In addition to those buttons, you can also click on the RRG plot itself and drag to change the position of the chart's origin.

Creating a Long-Term RRG Chart

Members can use the “Years” dropdown to create longer-term RRG charts. The choices available are 1, 3, 5 and 10-years. Longer duration charts take longer to load.

Note: A ticker symbol must have at least one year's worth of data in order to appear on an RRG chart.

Changing the Chart's Period

By default, RRG charts use weekly data in their calculations. Members can change the chart so that it uses daily data using the “Periods” dropdown located next to the “Update” button. For more details on comparing and interpreting weekly vs. daily RRG charts, see our ChartSchool article on RRG Charts.

Resizing an RRG Chart

Members can click and drag the resize icon in the lower right corner of the RRG chart to change the size of the chart. In addition, you can click the “Maximize” icon in the upper right corner of the chart to expand it to occupy the entire browser window.

Saving an RRG Chart

Members can click the “Permalink” link located below the symbol table to get a link to their chart that can be bookmarked and/or used in web links.
