Relative Rotation Graph (RRG)
A plot of relative strength and the momentum of that relative strength, used to see rotation between groups.
Formula
JdK RS-Ratio measures an instrument's trend of relative strength against a benchmark. JdK RS-Momentum measures the rate of change of that relative trend. Both are normalised so that 100 is the benchmark. The graph plots momentum on the vertical axis and the ratio on the horizontal. Quadrants, clockwise in the usual story: improving (momentum above 100, ratio below 100), leading (both above), weakening (momentum below, ratio above), and lagging (both below). Julius de Kempenaer developed the tool.
Definition
A relative rotation graph takes the relative-strength idea and adds the momentum of the ratio, then plots a universe of sectors or stocks as points that move through four quadrants. The visual is the point. You can see a group rotating from improving into leading, or rolling from leading into weakening, instead of reading twenty ratio lines. The usual motion is clockwise, and it is a tendency produced by the way the two measures are built, not a physical law. Points can jump, stall, or travel counterclockwise. The chart is a ranking and rotation display. It is not a price target and not a timing trigger by itself.
How it works
Read the quadrant and the direction of travel. A group in leading that is heading toward weakening is still strong and is losing momentum. That is a reason to be careful with new longs, not a short by itself. A group in improving that is heading toward leading is gaining relative momentum from a weak base. The long, if you take one, still needs a price setup in the actual instrument. Set the benchmark and the universe on purpose. An RRG of sectors against the broad index answers a sector question. An RRG of your watchlist against a sector answers a stock-selection question. Mixing universes makes the picture look precise and answers nothing.
How traders use it
Use RRG to narrow a list. Focus longs on groups in leading or entering leading, and demand a stronger price setup before you buy a group in lagging, unless your strategy is explicitly to catch reversals. Review it on a schedule, weekly if you swing trade, not every hour. The measures are smoothed, and refreshing them all day is how a slow tool gets misused as a fast one. When you take a trade from an RRG idea, the stop lives on the price chart of the instrument. There is no stop on a scatter plot.
Common mistakes
Treating the clockwise arrow as guaranteed. Also shorting a leading group only because it entered weakening. Weakening relative momentum can coexist with rising absolute prices for a long time. And comparing RRGs with different benchmarks or lengths as if the quadrants meant the same thing. The 100 line is relative to the settings. Change the settings and the points move.
Limitations
RRG inherits the limits of relative strength and adds smoothing lag. Turns in the plot happen after the ratio has already turned. The tool does not know absolute trend, so a leading group in a bear market is the thing falling least, which may still be a loss if you buy it. Crowded visualisations also create false confidence. A point near the centre is close to the benchmark and can change quadrant without a meaningful move. Do not trade the cross of 100 as an event. Trade the price, and let the graph be the map that told you where to look.
