LAYER 02A // ANALYST ECONOMIC MECHANISM & INFERENCE THESIS CASE

Why Capital & Cash Flows Move: Mara Quenwick's Causal Chain

Whether a hyperscaler trains on merchant GPUs (NVDA) or internal custom XPUs (AVGO), both paths converge on TSMC leading-edge wafers/CoWoS packaging (TSM), HBM memory stacks (MU), and 800G Ethernet switches (ANET).

MARKET EXPECTATIONS & CONSENSUS BENCHMARK NOTE

Watch monthly TSMC NT$ revenue prints and DRAM/HBM gross-margin progression to spot inventory digestion early.

LAYER 02B // THE OTHER SIDE — MANDATORY OPPOSING CASE (#8) EQUAL-WEIGHT COUNTER

High Correlation Basket Requires Strict Trend & Position-Sizing Discipline

All five names carry >0.75 pairwise correlation during semiconductor risk-off tape and export-control headlines. Owning all five at full size creates concentrated single-factor exposure rather than true diversification.

FALSIFIABLE DISCONFIRMING TRIGGER (“WHAT BREAKS THIS STORY”)

SOXX / TSM breaking below 200-day moving average alongside rising foundry inventory days.
