Energy breadth (XLE)

What it is

Energy breadth (XLE) — registry key sector_breadth_xle.

Per-sector breadth substrate — Energy sector % above 50d SMA. Promoted from the sector_breadth JSON blob to a dedicated REAL column so rotation history accumulates. Not scored/aligned; raw substrate for sector-rotation analysis.

Data-pyramid tier

T0 — Raw input. This metric sits at the raw input layer of the platform’s six-tier data pyramid (T0 raw inputs → T5 actionable read). The tier reflects how far the value is from a raw measurement — not how strongly it is validated. Abstraction and validation are separate axes: a higher tier is not a claim of stronger evidence.

Horizon & validation

No validated skill horizon is on file for this metric — read it as context / a data carrier, not a validated edge. Stamps are added only when a gated research verdict lands.

Source

Source module: breadth
Data source: back_fillable

Fetched directly from app/sources/breadth.py; see source code for the upstream API call and any provider-specific handling.

How it’s computed

Percent of S&P 500 Energy-sector constituents (from app/data/sp500_sectors.json) whose latest close is above their 50-day SMA. Same value as sector_breadth['Energy']['pct_above_50d'] in the JSON blob. See app/sources/breadth.py:_calculate_breadth.

Where it surfaces

Health-score / alignment role

Data carrier — no implication, no health-score contribution.

Persisted for downstream consumers (sparklines, base-rate matcher, calibration substrate) but does not classify into BULLISH / NEUTRAL / BEARISH and does not contribute to the 0-100 health score.
