The three-tier cascade pattern has been observed in two major market bubbles. Understanding how the pattern manifested historically helps interpret current signals.
Fiber optic companies like JDS Uniphase, Nortel's fiber division, and telecom equipment providers began showing stress as it became clear that far more fiber was being laid than could ever be used.
Cisco, Nortel, and Lucent continued rising even as infrastructure orders slowed. They peaked months after fiber companies, as channel stuffing and delayed recognition masked the slowdown.
Pure internet plays like Yahoo, Amazon, and later-stage dot-coms maintained hope longest. The narrative of "internet changes everything" persisted even as infrastructure collapsed.
The gap between Tier 1 and Tier 3 peaks was approximately 6-12 months. Infrastructure stress was visible well before the NASDAQ collapsed.
New Century Financial, Countrywide's subprime division, and home builders like Toll Brothers showed stress as housing demand slowed and subprime defaults rose.
Major banks like Bear Stearns, Lehman, and Merrill held mortgage securities. They fell after originators, as losses on securities materialized.
Tech and non-financial stocks held up longer. The full market crash came only after Lehman's failure and credit freeze.
The 2022 bear market was driven by Federal Reserve rate hikes and inflation, not sector-specific overbuilding. All tiers fell together.
This is why the framework has limited applicability - it only works for specific bubble types.
