Markets just wrapped a strong and strange month.
Here is what actually moved, what it means, and where to look as jobs week begins.
Let’s Get Into It.
Two things happened this month, and they do not fit together. The S&P 500 closed Friday at a record 7,581, the Nasdaq capped an 8% May at its own all-time high, and yet eight of eleven sectors finished the month lower. The index is green. Most of the market is not.
The split comes down to one trade. Information technology rose about 16% in May and the SOXX semiconductor index climbed 24%, while most sectors outside AI leaned lower. Dell’s earnings blowout Friday was the exclamation point. Here is the week, and the tell underneath it.
Five Stories That Moved The Market
Earnings › Dell’s AI-Server Blowout
Dell (NYSE:DELL) reported $43.8B in quarterly revenue and EPS of $4.86 against a $2.96 estimate, then raised its full-year guidance. The line that mattered was AI servers at $16.1B, up 757% from a year ago. The stock jumped roughly 30% Friday and added an estimated $62B in market value, pulling the rest of the AI hardware chain higher with it. Dell is now the clearest sign that the AI trade is widening beyond chips into servers, storage, and the full buildout.

2. AI Infra › The Trillion-Dollar Club Keeps Growing
There are now 14 public companies worth more than $1 trillion, led by Nvidia near $5.2T, Alphabet at $4.7T, and Apple at $4.5T. Micron crossed $1T for the first time this month and AMD topped $800B, both riding the same AI demand. The concentration cuts both ways: it is why the indexes keep printing records, and why so much now rides on a handful of names.
