US stocks closed higher on Wednesday, with AI infrastructure and semiconductor shares leading the recovery. The Nasdaq 100 rose 2.28%, followed by a 1.60% gain in the Nasdaq Composite. The Dow participated, but its 0.48% advance lagged the broader indices.
CoreWeave helped give buyers a reason to step back into the AI trade. Stronger revenue, higher guidance and management’s plans to address funding concerns eased some of the anxiety surrounding the company’s expansion. That encouraged buying across related shares, although the longer-term financing and profitability questions remain.
The rally also had participation behind it. Advancers outnumbered decliners across every group in the supplied breadth snapshot. However, the Mag 7 remained divided, with Microsoft, Meta and Amazon finishing lower.

AI infrastructure and chip shares lead the buying
The standout gains came from companies tied to AI computing capacity, memory, chip design and data-center connectivity. These were substantial moves, with all seven names below posting double-digit percentage gains:
-
CoreWeave: +$12.04 (+24.71%) to $60.77.
-
Nebius: +$20.69 (+15.44%) to $154.69.

-
Lumentum: +$62.49 (+10.67%) to $648.06.
The buying reached beyond the largest technology companies. Cloud infrastructure providers, memory suppliers, optical connectivity companies and power-related shares all featured among the winners. That gave the recovery more depth.
Mag 7: Four higher, three lower
Tesla and Nvidia led the gains, while Alphabet and Apple also advanced. Microsoft was the weakest performer.
-
Tesla: +$11.04 (+2.91%) to $390.82.
-
Nvidia: +$4.84 (+2.87%) to $173.73.
-
Alphabet: +$6.07 (+2.11%) to $293.45.
-
Apple: +$7.12 (+2.04%) to $355.63.
-
Amazon: −$4.70 (−1.74%) to $266.17.
-
Meta: −$12.62 (−1.97%) to $628.77.
-
Microsoft: −$12.03 (−2.26%) to $521.13.
The Nasdaq 100’s strong gain despite those three declining heavyweights highlights the strength elsewhere in the index. Buyers were making a play across a wider group of technology shares.
Market breadth supports the advance
The breadth of the market showed a positive split.
-
Dow: 18 advancing; 12 declining.
-
S&P 500: 311 advancing; 174 declining.
-
Nasdaq 100: 83 advancing; 17 declining.
-
Nasdaq: 1,933 advancing; 1,275 declining.
-
NYSE Composite: 1,030 advancing; 754 declining.
The Nasdaq 100 had the strongest participation, with nearly five advancing issues for every declining issue. Broader Nasdaq and NYSE breadth was positive, but less decisive. That points to a rally with widespread participation and a particularly strong concentration in large technology shares.
What traders can learn from today’s rally
An index gain tells you the direction. Breadth helps tell you how many stocks are participating.
Today, the Nasdaq 100 had both a strong percentage gain and strong participation. That is encouraging for buyers. But a sharp rebound alone does not establish a lasting change in trend. The next step is follow-through: buyers need to defend the recovery and continue making progress through resistance.
For individual stocks, the index is a useful barometer, but each stock still needs its own bias, risk and targets. Microsoft, Meta and Amazon were reminders of that today.
