In Focus: S&P 500

The Nasdaq (+1%) is now up more than one percent on the day, but for a real look across the market, the S&P 500(+0.73%) really tells the story this morning. In the index, four of the top ten performers this morning — that’s Oracle (+7%), Sandisk (+6.5%), Micron (+5.7%), and Advanced Micro Devices (+4.3%) — are AI-related trades.

Of the remaining equities, three are cruise companies; Carnival (+9.7%) is up nearly 10% after reporting strong results this morning, lifting peers Norwegian (+6%) and Royal Caribbean (+4.3%) in the process.

In total, 319 of the index’s 503 holdings are up today. Here’s how the index looked at last glance:

UM Consumer Sentiment Sees Modest Improvement in December

The University of Michigan’s Consumer Sentiment data is out now, coming in at 52.9 in its final report for the month of December. That was up from 51.0 last month, making this the third consecutive month of improvement in the soft data index.

Headlining the modest increase were moderating inflation expectations, as well as an overall increase in consumer expectations — those jumped from a score of 51.1 to 54.6. However, the current conditions index sagged, falling from 51.1 to 50.4.

In response, U.S. equities have appreciated a small bump after a healthy showing in the opening minutes of trading. Also helping matters, existing home sales also grew in the month of November to 4.13 million (+0.5% month-over-month).

Opening Bell

The U.S markets are now open. After a strong Thursday, equities appear to be fixing for a strong close to the final full week of 2025, putting the kibosh on what was shaping up to be a five day-long decline in the S&P 500. Instead, tech stocks are once again lifting benchmarks like the Nasdaq (+0.78%). The Russell 2000 (+0.62%), S&P 500 (+0.61%), and Dow (+0.42%) are all coming along for the ride on similar optimism.

Particularly consequential in this morning’s trade, Oracle (+5%) appears to be leading some of the early day charge after sagging in recent sessions on angst surrounding its debt-heavy data center projects. A report from earlier this week had indicated that the hyperscaler’s endeavors faced a funding shortfall after a key backer decided to sidestep the company’s $10 billion Michigan data center. This morning, it seems to be leading the charge higher in AI stocks.

Outside of equity land, the 10Y Treasury is 1.9 bips higher at 4.135%. Continuous futures in metals like Silver and Gold, as well as energy commodities such as natural gas and WTI crude are higher this morning.
