How the Framework Works

Important Disclaimer

This framework is based on historical analysis of only 2 sector-specific bubbles (2000, 2008). It has not been validated for all market conditions and failed to apply to the 2022 bear market. Use for educational purposes only.

The Core Insight

In certain types of speculative bubbles - specifically those driven by infrastructure overbuilding - companies at different layers of the tech stack fail in a predictable sequence:

TIER 1

Infrastructure

Data centers, fiber, power. Closest to physical deployment, first to feel demand shifts.

Falls First

TIER 2

Equipment

Chips, servers, networking. Sells to infrastructure builders.

Falls Second

TIER 3

Narrative

Platform companies, story stocks. Benefits from optimism longest.

Falls Last

Why This Sequence?

The cascade happens because of how information flows through the market:

Infrastructure companies see demand first - They're building physical assets based on customer orders. When orders slow, they know immediately.
Equipment makers see it second - They supply infrastructure builders. When data center construction slows, chip orders follow.
Narrative companies see it last - They're furthest from physical reality. Optimism about AI/internet/etc. persists even as underlying buildout stalls.

Historical Validation

2000 Dot-Com Bubble

Fiber optic companies (Tier 1) crashed first as telecom overbuilding became apparent. Network equipment makers like Cisco and Nortel (Tier 2) followed. Software and internet companies (Tier 3) were last to fall.

✓ Pattern confirmed

2008 Financial Crisis

Mortgage originators and home builders (Tier 1) failed first. Banks and mortgage servicers (Tier 2) followed. Broader financials and tech (Tier 3) fell last as contagion spread.

✓ Pattern confirmed

2022 Bear Market

This was a macro-driven decline (interest rates, inflation), not a sector-specific bubble. All tiers fell together. The cascade pattern did NOT apply.

✗ Pattern did not apply

Signal Interpretation

Signal	Meaning	Action
🟢 GREEN	All tiers healthy, no warning signs	Normal market conditions
🟡 YELLOW	Tier 1 showing stress, watch closely	Monitor for acceleration
🟠 ORANGE	Tier 1 stressed, Tier 2 starting to weaken	Cascade may be forming
🔴 RED	Multiple tiers in decline	Full cascade in progress

Limitations

Only validated on 2 historical examples
Does not work for macro-driven corrections
Requires sector-specific overbuilding to apply
Timing is imprecise - early warnings can be months early
Not a trading signal - educational only
