% from 52-week low

What it is

% from 52-week low — registry key screener_dist_52w_low.

Per-ticker percentage distance of close from its 52-week low: (close - low_252d) / low_252d. Typically zero or positive. Stored in screener_features_daily.

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: screener
Data source: computed

Derived metric — produced inside the platform (app/sources/screener.py or equivalent) rather than fetched as a raw upstream value. See the How it's computed section below for the formula.

How it’s computed

(close - min(close, trailing 252 days)) / min(close, trailing 252 days). NULL when fewer than 252 rows.

Where it surfaces

• API field: screener.features.dist_52w_low on GET /api/v1/signals/latest

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.
