US relative rotation graph (RRG)
Every US sector plotted against the S&P 500: how strong it is (RS-Ratio) and whether that strength is building or fading (RS-Momentum). Drop into a sector to see which industries inside it are actually carrying the move.
Not enough aligned history to draw the graph yet (276 sessions available). It needs roughly three months of sector and benchmark data. Check back after the next few end-of-day runs.
How to read this
The horizontal axis is relative strength against the S&P 500 — right of center means the group is beating the index. The vertical axis is the momentum of that strength — above center means the lead is still building. Both are measured against the group's own recent range rather than a fixed scale, so a position just past center is a real move, not a rounding error.
Read the quadrant and the direction of travel, not the absolute distance. Groups normally rotate clockwise (Improving, Leading, Weakening, Lagging), and a tail curling back toward the center is the earliest sign a run is ending. The most useful reading is a disagreement: something sitting in Leading with a tail already bending down is late, whatever the headline says.
Then check the breadth. The graph measures price against the S&P 500; breadth counts how many of the group's own stocks are in a Stage 2 uptrend. When the two point the same way the move is broad. A group whose momentum is rising while fewer of its stocks hold Stage 2 is marked price ahead: a handful of names is carrying it. One where more stocks are entering Stage 2 while momentum still falls is marked breadth ahead, and that is often how a turn starts.
