Analysis

Nvidia and Microsoft helped lead the Nasdaq Composite to a record close, Reuters reported. Earlier in the day, services businesses reported continued growth alongside higher costs, while Schneider Electric’s proposed acquisition sent PTC sharply higher. [2, 3, 4]

Nasdaq leads the advance

U.S. stocks ended Monday higher, with the Nasdaq Composite gaining 1.05% to a record close. The S&P 500 rose 0.66%, while the Dow Jones Industrial Average added 0.18%. [1, 2]

Reuters attributed the advance to large technology stocks, including Nvidia and Microsoft, as investors focused on lower oil prices and the approaching earnings season. Nvidia gained 2.1% and Microsoft 1.5%, according to its closing report. [2]

Services businesses report slower growth and higher costs

Earlier Monday, the Institute for Supply Management reported that its September Services PMI eased to 54.9 from 55.4 in August. Readings above 50 indicate expansion. Business activity and new orders slowed, while the employment index moved just above 50. [3]

The prices index climbed to 74.0 from 72.6, its highest reading since July 2022. Respondents cited fuel costs, tariffs and supply constraints. These indexes measure how broadly businesses report changes; 74.0 is not a consumer-inflation rate. The combination left a mixed picture: continued services growth alongside pressure on operating costs. [3]

PTC’s takeover agreement stands out

PTC rose about 33%, Reuters reported, after Schneider Electric announced an agreement to buy the industrial-software company. [2] The companies set a cash price of $205 a share, valuing PTC’s equity at approximately $22.6 billion. Schneider said the combination would connect product-design and engineering information with its industrial and energy software. That is the companies’ strategic rationale, not an achieved outcome. Shareholder and regulatory approvals and other closing conditions remain outstanding. [4]

Sources and coverage

The table shows October 5 cash-index closing levels agreed by Yahoo Finance and Reuters, whose closing report was updated at 4:26 p.m. EDT. Yahoo was retrieved at 4:31 p.m. EDT; its provider clocks are post-close updates, not a common 4 p.m. observation. [1, 2] The regular session ended at 4 p.m. EDT, and October 6 is the next scheduled NYSE trading day. [5]

What remains uncertain

Reported market drivers do not establish a single cause for index moves. ISM’s survey is not a consumer-inflation measure, and the PTC acquisition remains subject to closing conditions.
