On Monday, the Dow Jones Industrial Average diverged from other major indices, experiencing a slight decline of 40 points or 0.1%. Out of its 30 constituents, around 21 faced losses, contrasting with gains in the S&P 500 and Nasdaq Composite at rates of 0.4% and 0.7%, respectively. Beneath this surface-level performance, broader market struggles were evident; only about one-third of S&P stocks were poised to close higher that day. The Invesco S&P Equal Weight ETF mirrored this lackluster trend by also dropping by approximately 0.1%. As Wall Street entered a holiday-shortened week, sentiment among traders remained cautious aside from optimism surrounding large technology firms.

The uptick in the S&P and Nasdaq was primarily driven by strong showings from Big Tech companies and semiconductor shares; however, the Dow lags as it has lesser tech exposure compared to its counterparts due to its price-weighted structure resulting in Nvidia’s modest gain contributing less than UnitedHealth Group’s increase despite differing absolute performances.

In terms of sector performance within the S&P index on that day, most sectors showed declines except for technology which rose slightly by up to 0.7% while consumer discretionary advanced marginally at just above zero percent; health care remained unchanged amid dips exceeding half a percentage point across other key sectors.
