Click any layer for details. Layer 4 (Machine Makers) is the critical confirmation signal.
Analysis
Small-cap semiconductors down more than 20% from yearly high. Lowest liquidity always turns first. The strongest leading indicator in the model — often months ahead of the index.
"The small names first"
— Jay Medrow
Analysis
SOX index -12.4% across 7 consecutive sessions. Distribution days visible — high volume on down closes. Micron and SK Hynix crossed a trillion dollars and Wall Street celebrated. The cascade had already begun.
"Then the giants"
— Jay Medrow
Analysis
SOX at 11,137 — more than 10% below recent peak. Micron inventory guidance will confirm. When end-demand stops, the capex cycle reverses — foundries feel it before machine makers.
"Then the factories that build the chips"
— Jay Medrow
Analysis
LRCX closed at $277.46 (-3.30% on Oct 15). KLAC -3.74% on Oct 15. ASML and AMAT still to confirm. When all four roll over, the cascade is complete — this is the critical confirmation signal.
"Then the machine makers"
— Jay Medrow
Analysis
S&P 500 Equal Weight still relatively stable. Indices are always last. The crowd watches the scoreboard. The operator watches who is still on the field.

2000 — ✅ Confirmed
Perfect cascade. Small-caps turned Q4 1999, machine makers summer 2000. Lead time Layer 1 to Layer 4: ~6 months. $5 trillion in market cap destroyed.
2008 — ⚠ Partial
L1 (Russell 2000) turned July 2007 — 14 months before the bottom. But a macro shock (credit/real estate) drove the crash, not tech. Layers 3 and 4 did not follow the semi cascade.
2022 — ✅ Confirmed (Strongest)
Strongest confirmation. Small semis peaked November 2021. ASML was literally the last semiconductor stock to roll over — exactly Medrow's prediction. Lead time L1→L4: ~8 months.
2026 (now) — ⚠ Active
Layers 1–3 confirmed. Layer 4 starting to turn. Index still stable. Rotation or crash — Layer 4 must fully confirm before calling the top.
Model Validity
2 out of 3 tech-driven crashes fully confirmed by the cascade. The 2008 exception was a macro credit shock — the model performs strongest during sector-specific tech tops, not broad financial crises.
Concrete threshold rules to minimize subjectivity. Always combine with quantifiable indicators.
⚠
Layers 1 + 2 confirmed
Raise vigilance. Actively monitor Layer 3 inventory guidance from foundries.
MEDIUM
⚠⚠
Layer 3 (Foundries) confirms
Begin defensive positioning. Consider hedges on SOXX or QQQ puts.
HIGH
⚠⚠⚠
Layer 4: ASML / AMAT / LRCX below 50-day MA
Strongest confirmation of structural top. Full cascade complete. Act accordingly.
CRITICAL
Layer 4 Threshold Rule (Most Critical)
SAFE
ASML + AMAT + LRCX all above their 50-day MA
ALERT
2 of the 3 below their 50-day MA
ALARM
All 3 below 200-day MA + declining guidance in earnings

Model Limitations
Not quantifiable — no exact threshold defines "roll over". Performs better during tech-driven tops than macro shocks (see 2008). Rotation vs. crash is only clear once Layer 4 fully confirms. Always use alongside yield curve inversion, Shiller CAPE, and VIX readings.
