Chip selloff deepens as funds rotate from AI-server names to CPO, ABF and MLCC
Taiwan's benchmark index closed up 0.22% at 49,822.55 on Oct 7, while the Philadelphia Semiconductor Index fell 1.15% to 13,066.15 and TSMC's ADR slipped 0.72% as the US 10-year Treasury yield rose to 5.28%, near a 24-year high; Taiwan futures dropped below the 50,000 mark in overnight trading. The three main institutional investor groups sold a combined NT$24.16bn, concentrated in AI-server, ASIC IP and semiconductor test-interface names, with money rotating into co-packaged optics (CPO), ABF substrates and high-end CCL, MLCC passive components, and petrochemicals. The report says AI servers use 3–5x more MLCCs than conventional servers and that the ABF substrate shortfall runs through 2027.
The rotation shows markets repricing AI-server supply-chain valuations, though the drivers cited are brokerage and trading-desk observations rather than confirmed industry fundamentals.
