The Atlas Continuity Index™ is built on a three-layer signal framework. This page describes the framework at a conceptual level. Proprietary calibration weights, scoring logic, and model parameters are not disclosed.
Atlas measures continuity pressure and earnings durability risk by monitoring the conditions under which adviser population decisions are formed — not by predicting individual outcomes. The framework is designed for institutional use: it informs due diligence, portfolio monitoring, and capital allocation decisions.
This framework uses public market data, FCA datasets, behavioural analysis, and Atlas proprietary calibration models. No individually identifiable adviser data is used in the index. Firm-level outputs are aggregated population measures.
The index is updated weekly. Scores are produced for each monitored firm at the close of each reporting period. The index universe currently covers 47 UK wealth management consolidators, platforms, and advisory firms.
Structural signals capture the underlying demographic and relational architecture of an adviser population — factors that are slow-moving but predictive over longer windows.
Structural signals typically account for the largest share of long-run continuity risk but produce slower-moving index changes.
Behavioural signals capture current and near-term adviser population dynamics — patterns of action and positioning that indicate mobility decisions in formation.
Behavioural signals tend to lead structural changes and are the primary driver of week-on-week index movements.
Environmental signals capture external and firm-level events that alter the context in which adviser population decisions are made — including ownership change, leadership transition, and competitive market events.
Environmental signals are the highest-volatility component of the index. A single confirmed event can produce a significant single-week movement.
The Signal Layer™ is the composite output of the three signal categories. Each week, signals are collected, scored against the Atlas calibration model, and combined into the firm-level continuity score. A recency weighting function ensures signals decay when no longer supported by current market evidence.
The recency decay mechanism prevents the index from becoming a permanent record of past events rather than a current-state risk measure.
The Adviser Mobility Score™ (AMS) is a firm-level aggregate measure of the probability-weighted tendency of adviser population departure within a defined forward window. It is derived from the Signal Layer™ and calibrated against Atlas proprietary datasets of historical adviser movement across the UK wealth management landscape.
The AMS is a population-level risk measure used for firm comparison and portfolio monitoring — not a prediction of individual adviser departures.
The Firm Vulnerability Index™ (FVI) combines the AMS with earnings durability modelling to produce an integrated assessment of the risk that adviser continuity pressure translates into material revenue impairment post-transaction or post-event. The FVI is the core output of commissioned diagnostic engagements.
The FVI is not published in the public index. It is produced only as part of a full firm-level diagnostic engagement.
Each monitored firm is assigned a continuity grade alongside its numeric score. Higher grades indicate greater continuity resilience — a firm with fewer active signals and a more stable adviser population.
| Grade | Tier | Score range | Continuity profile | Typical institutional read |
|---|---|---|---|---|
| AA | Resilient | 0 – 14 | Low continuity pressure. Adviser population stable. Few active signals. | Continuity risk is not a primary concern. Monitor for changes. |
| A | Stable | 15 – 24 | Moderate signals present. No acute risk concentration. | Continuity risk is manageable. Track for signal accumulation. |
| BBB | Elevated | 25 – 49 | Meaningful continuity pressure. Multiple signal categories active. | Elevated caution warranted. Pre-transaction diligence recommended. |
| BB | Severe | 50 – 74 | High signal concentration. Risk of material adviser loss. | Serious continuity risk. Full diagnostic recommended before any transaction. |
| B | Critical | 75 – 100 | Acute continuity pressure. Population in advanced mobility state. | Continuity risk is a primary value driver. Not suitable for standard DD approach. |
Full diagnostic engagements apply the complete Atlas framework — including the Firm Vulnerability Index™ — to a specific target firm. Suitable for pre-acquisition due diligence, portfolio review, and live event monitoring.
