GlobalFoundries-TSMC interposer milestone precedes U.S.-Japan fab construction

Scenario description

Assume that by 2027-06-30 the GlobalFoundries-TSMC New York silicon-interposer program has a documented tooling, qualification, or accepted pilot milestone, while the first U.S.-Japan-backed fab has not begun confirmed funded construction. AI-packaging supply-chain diversification may move ahead of the larger fab capital buildout, without claiming 2027 high-volume interposer or chip production.

The bigger picture

A diversified portfolio is broadly unchanged at 0%, but the calm headline masks a sharp rotation within technology.
Technology falls 0.1%, losing $20.5B, as weaker equipment orders outweigh improved semiconductor availability.
Consumer Non-Cyclicals and Consumer Cyclicals each rise 0.1%, gaining $6.35B and $3.60B as supply and logistics pressures ease.
Technology records the largest dollar loss partly because it is the largest covered sector, not because every technology business is equally exposed.
