--- title: "Market Fragility Index: Score" description: "Swoopr Market Fragility Index: 0-100 vulnerability score covering concentration, breadth, leverage, credit, liquidity and cross-asset instability." canonical: https://www.getswoopr.com/market-intelligence/market-fragility-index/ source: "Swoopr Investment: https://www.getswoopr.com" --- ## Direct Answer > Swoopr Market Fragility Index is a 0-100 vulnerability score that distinguishes calm conditions from resilient conditions by measuring concentration, narrowing breadth, leverage, credit, liquidity and cross-asset instability. It is designed to answer one narrow question: How vulnerable is the market structure if a shock arrives? The output is educational market context, not a forecast, recommendation, or promise of future returns. # Swoopr Market Fragility Index Swoopr Market Fragility Index: 0-100 vulnerability score covering concentration, breadth, leverage, credit, liquidity and cross-asset instability. Full methodology, interpretation bands and source references. ## Why Swoopr Is Building This Low volatility and calm prices can coexist with fragile structure. The Fragility Index distinguishes genuine resilience from temporary calm, providing a structural vulnerability read rather than a movement or direction signal. Swoopr already publishes market tools, a live proprietary Fear and Greed gauge, a sentiment dashboard, macro and regime education, portfolio diagnostics and a market-history library. This product makes one missing question measurable, explainable and reusable across the site. ## What It Measures The model draws from the following evidence families: - Market and leadership concentration - Breadth deterioration - Volatility compression and term structure - Credit-spread behavior - Cross-asset correlation - Margin and leverage context - Speculative participation - Valuation pressure - Liquidity deterioration - Price and breadth divergence ## Scoring Methodology Each component is normalized to a 0-100 historical percentile score. For a raw value *x*: `component_score = percentile_rank(x within approved history) * 100` Where a higher raw value represents more resilient conditions, the score is inverted: `adjusted_score = 100 - component_score` The composite is: `composite = sum(weight_i * adjusted_score_i) / sum(active_weight_i)` ## Interpretation Bands | Score range | Label | | --- | --- | | 0-24 | Resilient | | 25-39 | Low fragility | | 40-59 | Balanced | | 60-74 | Elevated | | 75-100 | Highly fragile | Bands are communication aids, not natural laws. The reading always shows the numeric value, trend and component contributions. ## FAQ ### Is Swoopr Market Fragility Index a bear market signal? No. It measures structural vulnerability, not direction. A highly fragile market can continue rising, and a resilient market can still fall on news or exogenous events. ### How is fragility different from volatility? Volatility measures realized or expected price movement. Fragility measures structural vulnerability to amplification. A low-volatility, narrow-breadth, high-leverage environment can read as calm on volatility metrics while scoring high on fragility. ### What happens when data are missing? The affected component is excluded under a predefined rule, coverage falls, and the product shows this to the user. Missing data are not converted to a neutral score. ### Does a high fragility score mean I should sell? No. The score is educational market context. It describes structural conditions, not a recommended action. High fragility has persisted for months in historical markets without a correction occurring. ### How is this different from the Market Health Index? Market Health answers: Is the market actually healthy underneath the headline index? Fragility answers: How vulnerable is the market structure if a shock arrives? They are related but address different structural questions and are cross-linked rather than merged. ## Methodology Version and Source Provenance ### Current Version | Field | Value | | --- | --- | | Version | v1.0 | | Effective date | 2026-09-30 | | Methodology policy | [Swoopr Investment: Data & Methodology Policy](https://www.getswoopr.com/legal/data-methodology/) | ### Change Log | Version | Date | Summary | | --- | --- | --- | | v1.0 | 2026-09-30 | Initial published version.
