What NPX-100 measures

Calibrated assessment of the 100 firms most likely to redefine fiduciary stewardship in the next decade.

i.

Methodology-hash stable

The SHA-256 of the methodology has been unchanged since v1.0.0 ratification. The v2.1 release was an operational amendment (governance, publication cadence, band tightening) — not a methodology change. The hash is published with every quarterly cycle.

ii.

7-axis composite

Each constituent scored across seven calibrated axes: capital efficiency, fiduciary alignment, prediction-track-record, methodology-transparency, governance, audit-independence, and durability-horizon. Weights are published. Per-axis sub-indices available to Trustee tier.

Quarterly publication ritual

First Tuesday of February, May, August, November. Reconciliation, Brier ledger, hash, revenue disclosure, confluence matrix, steward attestation, sub-index roll, annual auditor letter (Q1 only). The ritual does not move.

Next cycle: 2026-08-04
Sub-index family

NPX-100 is the apex. The family extends.

The flagship publishes; the sub-indices specialize. Methodology hash inherits from NPX-100 with documented per-family deltas. All sub-indices follow the same quarterly ritual.

The mic drops quarterly

Most indices publish a number. NPX-100 publishes a verdict.

Every constituent change carries a stated reason. Every reweighting carries a Brier prediction. Every prior cycle's predictions get scored at this cycle's publication. The constituent list isn't an outcome of a black-box optimization — it's a verdict by named stewards who carry personal accountability.

"The case is closed in 18 karat."

The full constituent list publishes 2026-08-04. Trustee Tier sees it 24h early.
