Two things happened in markets yesterday and they appear to contradict each other.
The Dow Jones Industrial Average hit an all-time high. Broadcom fell 15%, its worst session in over a year, dragging the broader semiconductor index down 2.2%. AMD fell 4%. Intel fell 3%.
The surface reading is that the market is healthy and diversified, that when one sector stumbles the rest picks up the slack. About 360 companies in the S&P 500 rose on Thursday. The rotation out of chips and into more economically sensitive, consumer-facing stocks was orderly. Nothing broke.
The deeper reading is less comfortable. The S&P 500 has spent the past two years with its heaviest concentration in a handful of technology names in its recorded history. When those names were rising, they pulled the index with them and made the broad market look healthier than it was. The moment those same names face even modest guidance disappointment, the index loses its primary engine and the rotation into other sectors can only compensate so much.
Broadcom beat earnings. AI chip revenue grew 143% year on year. The stock still fell 15% because the guidance for next quarter, while above consensus, did not exceed the expectations that had been built into a stock up 88% over the prior twelve months. That is the definition of a crowded trade unwinding, not a company failing.
The Dow hitting highs on the same day tells you that capital is not leaving the market. It is rotating. But rotation out of the sector that has been carrying the market’s valuation for two years is not a minor technical adjustment. It is a repricing of the thesis that has justified where markets are trading.
The Dow at all-time highs. Chip stocks down 15%. Watch which of those two headlines is still relevant in six months.
