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.

Leading 1

RS > 100 and 21d outperformance positive — strongest cohort

  • XLE Energy -2.5%
Improving 2

RS < 100 but 21d outperformance positive — momentum rebuilding

  • XLF Financials +6.2%
  • XLB Materials -2.7%
Weakening 3

RS > 100 but 21d outperformance turning negative — rotation candidate

  • XLV Health Care +9.0%
  • XLK Technology +4.9%
  • XLI Industrials +0.7%
Lagging 5

RS < 100 and 21d outperformance negative — broadly out of favor

  • XLRE Real Estate -3.8%
  • XLP Consumer Staples -3.9%
  • XLY Consumer Discretionary -5.8%
  • XLU Utilities -8.7%
  • XLC Communication Services -10.9%

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 2026-08-07, XLV (Health Care) ranks #1 of 11 SPDR sectors by 63-day outperformance vs SPY, at +9.0%.

Which SPDR sector is lagging the most?

As of 2026-08-07, XLC (Communication Services) ranks last (#11 of 11) by 63-day outperformance vs SPY, at -10.9%.

How many sectors are in the Leading quadrant?

As of 2026-08-07, 1 of 11 SPDR sectors sit in the Leading quadrant (RS-ratio above 100 with positive 21-day outperformance vs SPY); 5 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.
