Microsoft and Caterpillar Lift the Dow to a Large Gain While Meta Weighs on the Nasdaq 100

The Dow's advance stood out from a more modest S&P 500 gain as Microsoft powered all three indexes while Meta and a cluster of software and chip names pulled the Nasdaq 100 back.

The S&P 500 closed at 7,743.41, up 39.28 points, a move of 0.51% on the day. Breadth was solidly positive, with 325 of the index's 496 members higher, though the index's own gain leaned on a small group of names: the top five contributors made up 69% of the day's points, a narrow concentration by the index's own measure.

Microsoft did the heavy lifting, adding 16.33 points on a 3.66% gain, more than any other name in the index. Apple added 9.25 points on a 1.53% move, and Nvidia, JPMorgan, and Broadcom rounded out the top five with contributions of 1.48, 1.48, and 1.45 points respectively. On the other side, Meta Platforms was the single biggest drag, subtracting 7.39 points on a 3.33% decline, followed by Intel, Tesla, Palo Alto Networks, and CrowdStrike, all lower on the day.

The Dow

The DJIA closed at 51,829.00, up 479.02 points, a move of 0.93%, roughly double the S&P's percentage gain. Breadth was broad, with 22 of 30 components higher, and the top five contributors accounted for 58% of the day's points, a wider spread than the S&P's own math. Microsoft was again the largest single contributor, adding 108.41 points, but the Dow's story diverged from the S&P's beyond that: Caterpillar added 97.06 points on a 2.03% gain, Goldman Sachs added 72.27 points, Sherwin-Williams added 51.71, and Amgen added 50.94, none of which show up among the S&P's leaders. Salesforce was the Dow's biggest drag, subtracting 24.96 points on a 1.76% decline, with IBM, Chevron, Visa, and McDonald's also lower.

The Nasdaq 100

The Nasdaq 100 closed at 30,608.13, up 129.27 points, a move of 0.42%, the smallest percentage gain of the three indexes today. Breadth was more mixed here, with 65 of 99 members higher, and concentration ran to 94%, far narrower than either the S&P or the Dow. Microsoft contributed 69.42 points and Apple added 38.52, and the two Alphabet share classes together added 22.76 points. Nvidia added a modest 6.05 points. The index's laggards were the same five names dragging on the S&P: Meta subtracted 33.86 points, Intel 11.89, Tesla 11.8, Palo Alto Networks 6.36, and CrowdStrike 4.08, a heavier weight here than in the broader index given the Nasdaq 100's tighter membership.

The sectors

Across the eleven sectors, the spread ran from a gain of 0.94% to a decline of 0.92%. Industrials led at 0.94%, followed by Technology at 0.79% and Financials at 0.53%. Energy and Communication Services were the only two sectors in the red, down 0.86% and 0.92% respectively.

The 11 sectors by move, top contributor named

Industrials was the day's strongest sector, up 0.94% and adding 1.59 points, with General Electric its top named driver, contributing 0.25 points on a 2.33% gain.

Industrials: what moved it

Communication Services was the weakest sector, down 0.92% and losing 1.05 points. Meta Platforms was the primary driver of that decline, subtracting 0.88 points on its 3.33% drop, consistent with its role as the largest single drag across both the S&P 500 and the Nasdaq 100 today.

Communication Services: what moved it

Set against the past year, today's Dow move ranks in the 88th percentile, a large move by this note's standard. The S&P 500's 0.51% gain sits in the 71st percentile, and the Nasdaq 100's 0.42% gain sits in the 60th percentile, neither large enough to earn that label.
