Sector Rotation: Dispersion Slips Into Transitional-Low

Energy XLE drove the week's sharpest advance deeper into the Leading quadrant.

Compressed gaps across the eleven S&P 500 sector ETFs leave a muted stock- and sector-selection market in a transitional-low regime as of September 4. The dispersion z-score against its GARCH-normalised mean is -1.10, and the spread narrowed modestly over the past five sessions. The low reading is fresh and mean-reversion-prone, so the weekly signal sits in relative rotation at the margin.

 

Energy XLE drove the week's sharpest advance deeper into Leading. It ranks first at +0.32, and its positive 20-day and mildly positive 13-week lines leave the leadership emerging. Utilities XLU posted a near-matching upswing and jumped six places to second; its Lagging base and negative readings on both horizons mark the move as a rebound. Technology XLK rose to third after a two-place climb in rank, even as its five-session motion faded on both horizons from the Improving quadrant. Health Care XLV holds fourth after a nearly flat week, and Financial XLF strengthened into fifth from an already positive base. The upside mix pairs two confirmed leaders with two recoveries and one emerging leader, so rank reshuffling dominates a stable intermediate core.

 

Materials XLB led the downside rotation and slipped two places to ninth, with deterioration on both horizons from a lagging base. Consumer Discretionary XLY followed to the bottom at -0.33, and Industrial XLI filled out the deteriorating cluster at eighth after another downside turn. Communication Services XLC rolled lower to sixth from an improving state, while Consumer Staples XLP and Real Estate XLRE edged higher over the week but held seventh and tenth because both bases are negative. Five of the eleven sectors hold positive current-week readings. The breadth split sits in the state profile: the positive half draws on confirmed leadership or tactical recovery, and the fading half is concentrated in lagging bases with thin 13-week backing.

How to read this table
13W Z: 13-week risk-adjusted relative strength versus the equal-weighted sector basket (Z-score). Structural baseline — table is sorted by this, strongest at top.
20D Z: 20-day risk-adjusted relative strength. The tactical trend.
5D Z: 5-session average relative strength. Current-week standing.
Velocity: 5-session change in 20-day relative strength (positive = building, negative = fading). The direction of the chart tail.
Quadrant: Leading = 13W ≥ 0 & 20D ≥ 0; Improving = 13W < 0 & 20D ≥ 0; Weakening = 13W ≥ 0 & 20D < 0; Lagging = both negative.
State: Leadership archetype derived from all three horizons and velocity signals.
