Asia bought back part of the chip sell-off this morning. The Kospi rose 3.3% to about 5,740, with Samsung Electronics up 4.0% and SK Hynix up 2.4%; the Nikkei gained 1.8%.

The S&P 500 is only 0.9% below its 6 October record, but the money has changed seats. Since then the health care fund rose 6.0% to a six-month high and consumer staples 6.0%, while technology lost 6.3% and chips 12.7%. Industrials look weak only because the AI build-out hides inside them: Vertiv, Caterpillar, Quanta, GE Vernova and Eaton fell 10–15%, while defence and rail rose.
