Semiconductor ETF falls 6.98% Friday, leading US sector ETF declines

The scale of the semiconductor move stands out even against a broadly weak tech tape, with the chip ETF's loss outpacing both the global tech and tech sector funds by a wide margin — a sign that selling concentrated in the most cyclical part of the complex rather than spreading evenly. The energy bid alongside tech weakness points to a rotation story, reinforced by October's split between telecom and tech losses and energy's double-digit gain. Whether that sector dispersion persists into the next session is the open question.
