Headline (Forex.com, early Sept): "Nasdaq 100 forecast: QQQ falls amid a rotation out of tech" as investors flee stretched chip/AI valuations. Layered on that, the Sept 1 U.S.-Iran escalation and oil spike lift yields — a direct headwind for long-duration tech — and QQQ, unlike the S&P, has no energy weighting to cushion the risk-off. Expecting a down day as the rotation and yield pressure dominate.
