A Visual Guide to Sector Rotation and Market Leadership

Understanding the Relative Rotation Graph (RRG)

The Relative Rotation Graph (RRG) is an advanced charting technique that plots sectors on a coordinate system showing both their relative strength (RS-Ratio) and momentum (RS-Momentum) versus the S&P 500 benchmark. The unique tail-like visualization shows the historical path each sector has traveled, making it easy to identify rotation patterns and predict future movements.

Key Metrics Explained

RS-Ratio (X-Axis)
Measures relative performance vs. benchmark. Above 100 = outperforming, below 100 = underperforming.
RS-Momentum (Y-Axis)
Shows the rate of change in relative strength. Above 100 = strengthening, below 100 = weakening.

The Four Quadrants: Your Roadmap to Sector Rotation

Sectors typically rotate clockwise through these quadrants over market cycles

Top-Left Quadrant

Improving

Currently underperforming (RS-Ratio below 100) but showing signs of life with improving momentum (RS-Momentum above 100). These sectors are bottoming and may be preparing to rotate into leading. Early entry opportunities.

Action: Begin accumulation, watch for breakout

Top-Right Quadrant

Leading

These sectors are the market leaders with strong relative strength (RS-Ratio above 100) and positive momentum (RS-Momentum above 100). They're outperforming the benchmark and accelerating higher. This is typically where you want to be invested.

Action: Maintain positions, add on pullbacks

Bottom-Left Quadrant

Lagging

The weakest sectors with both underperformance (RS-Ratio below 100) and negative momentum (RS-Momentum below 100). These sectors are falling behind the market and losing ground. Typically best avoided or used for tactical shorts.

Action: Avoid or reduce to minimum allocation

Bottom-Right Quadrant

Weakening

Still outperforming the market (RS-Ratio above 100), but momentum is slowing (RS-Momentum below 100). These sectors may be topping out and preparing to rotate into lagging. Watch for breakdown signals.

Action: Take profits, reduce exposure

Reading the Tails. The colored lines show each sector's recent path. Longer tails indicate faster movement. Watch for sectors making sharp turns at quadrant boundaries - these often signal major trend changes.

Why Professional Investors Use RRG

  1. Anticipate Market Leadership Changes

    See which sectors are rotating in and out of favor before major moves occur

  2. Improve Entry & Exit Timing

    Time your sector allocation based on position and trajectory, not just price action

  3. Enhance Portfolio Diversification

    Maintain exposure to different rotation stages for balanced risk/reward

  4. Identify Early Opportunities

    Spot sectors transitioning from improving to leading before the crowd notices

Pro Tip

Watch for sectors with short tails near quadrant boundaries. These are coiling up for potential explosive moves. The longer a sector stays in improving, the stronger the eventual breakout to leading tends to be.
