🕰️ Long-Term Burst Probability
The Long-Term Burst Probability estimates the risk of entering a multi-year bear market to find a structural bottom. It uses a Systemic Fragility Model:
P(Long Term Bear Market) = P(Systemic Fragility)
The Systemic Fragility is mapped using an exponential asymptote (never touching 100%) driven by three factors:
- Absolute Bubble Size: How dangerously high the core Bubble Index is currently sitting.
- Technical Overextension: Extreme price deviation from the 200-day Moving Average.
- Macroeconomic Headwinds: Contraction in market liquidity, widening credit spreads, and most importantly, elevated US 10-Year Treasury Yields (>4.0%) which structurally crush tech valuations.
📉 2000 Dotcom Bubble Burst Index
This is a historical reference point representing the Burst Risk Index at the peak of the 2000 Dotcom Bubble. To make it directly comparable to the current Risk Index (which includes a massive base score derived from the current macro environment), we apply a 0.4x weighting multiplier to the uncapped historical P/V score before adding the current macro base.
- Uncapped 2000 P/V Score: Uses the same algorithms for Slope and Volume, but allows the deviations to exceed 100%.
- Adjusted Score: The historical price/volume score is scaled down to match the new V2 model weights, and added to the current macro base. This answers the question: "If the dotcom price action happened in today's macro environment, how high would the index be?"
This establishes an accurate historical ceiling, making it obvious when a stock's current bubble is approaching dotcom levels. The calculation was performed once using historical data and is hardcoded in dotcom-burst.json.
