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.
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 worse 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.
