The AI Build-Out Trade Breaks
The S&P 500 had its worst day since April 2025 as the AI hardware trade unwound, and every sector fell.
The Signal
Broad, fear-driven selling with tech at the center: every sector fell and only about one stock in seven rose. Memory, storage and chip names led the drop, with SanDisk, Lumentum, Micron, Western Digital and AMD all down more than fifteen percent, while NVIDIA, Broadcom and Tesla dragged the indexes. Staples and utilities held up best. AppLovin jumped on earnings. Payrolls land Friday and CPI on Tuesday.
The Noise
The market is telling itself the AI boom is over. The worry is narrower: power, funding and data-center permitting under a new Congress. Flow readings still look healthy, but that is lag after a one-day crash; price structure already shows more lower highs than higher highs.
Multi-Signal Confluence
Broadcom: fell about ten percent with no company-specific news and is now more than ten percent below its late October signal, so the dip setup is active. Revenue up about half, earnings roughly doubled, around 37 times trailing. Heavy selling and a projected target about ten percent lower; NVIDIA reports November 17.
Vertiv: data-center power and cooling, right on the bottleneck the market fears. Signed a three-year chip supply deal with Infineon this week. Revenue up about a third, earnings roughly doubled, around 33 times trailing. Setup active, a few more percent of projected downside.
ON Semiconductor: the weakest setup. An aging August signal, lower lows, and a projected target nearly twenty percent below. Revenue growth about three percent and a bank target cut. Wait for the price to stop falling.
