Sector Relative Strength.
Rotational rankings of the eleven SPDR sector ETFs against the S&P 500 (SPY). Each sector gets four readings: an RS-ratio (sector / benchmark, normalised to 100 a year ago), 21-day · 63-day · 252-day outperformance in percentage points vs SPY, and a Z-score of the current RS-ratio against its trailing 63-day mean — a mean-reversion signal. Sectors are sorted by 63-day outperformance descending and assigned a JdK-style RRG quadrant.
Sector charts
Compare any of the 12 SPDR ETFs + SPY side-by-side. Per-cell ticker, range, and oscillator toggles. Reuses the same indicator set as the Rubin charts terminal — including Directional Flow (DF) and DF % (the 0-100 tanh-normalised view).
The rule
For each sector ETF: compute the relative-strength ratio against SPY, normalise it to 100 at the start of a 252-day window, and track its level and trajectory. Sectors above 100 with positive short-term outperformance are leading; sectors below 100 with negative outperformance are lagging. The remaining two quadrants — weakening and improving — are the rotation candidates.
The Z-score against the trailing 63-day mean is the mean-reversion overlay: a sector with Z > +2 is statistically stretched relative to its own recent history; a sector with Z < −2 is unusually compressed. Both edges are candidates for reversal, regardless of which quadrant they currently occupy.

Rankings · three timeframes, separately sorted
Same eleven sectors, three independent sort lenses. A name that leads on 21d but lags on 252d is a fresh rotation candidate; one that leads on 252d but lags on 21d is a tired leader. The full picture only emerges when all three horizons are read together.

By quadrant
JdK-style RRG mapping. RS-ratio on the vertical axis (above / below 100), 21-day outperformance on the horizontal axis (positive / negative). The four quadrants encode where each sector sits in its rotational cycle.
RS > 100 and 21d outperformance positive — strongest cohort
- XLE Energy +15.6%
- XLV Health Care +9.3%
- XLK Technology -1.8%
RS < 100 but 21d outperformance positive — momentum rebuilding
- XLC Communication Services -0.0%
RS > 100 but 21d outperformance turning negative — rotation candidate
- — none
RS < 100 and 21d outperformance negative — broadly out of favor
- XLF Financials +0.6%
- XLP Consumer Staples -2.7%
- XLRE Real Estate -4.7%
- XLB Materials -5.3%
- XLY Consumer Discretionary -6.5%
- XLU Utilities -8.8%
- XLI Industrials -8.9%
Sector RS is a structural overlay. It says where dispersion sits across the SPDR cohort and which sectors are entering or leaving the leading-quadrant cluster. It does not say what to do about it; that's a function of the user's framework (regime, time horizon, mean-reversion vs. momentum bias).

Quick answers
Which SPDR sector is leading on relative strength right now?
As of 2026-09-17, XLE (Energy) ranks #1 of 11 SPDR sectors by 63-day outperformance vs SPY, at +15.6%.
Which SPDR sector is lagging the most?
As of 2026-09-17, XLI (Industrials) ranks last (#11 of 11) by 63-day outperformance vs SPY, at -8.9%.
How many sectors are in the Leading quadrant?
As of 2026-09-17, 3 of 11 SPDR sectors sit in the Leading quadrant (RS-ratio above 100 with positive 21-day outperformance vs SPY); 7 sit in Lagging.
What does the Z-score column mean?
It is the current RS-ratio expressed as standard deviations from its own trailing 63-day mean — a mean-reversion overlay independent of the quadrant. A reading beyond +/-2 marks the sector as statistically stretched or compressed relative to its recent history.
