Market Summary

The U.S. equity markets closed a choppy session on a mixed note, characterized by significant sector rotation and a tug-of-war between geopolitical optimism and tech sector weakness. The Dow Jones Industrial Average managed to finish in the green, gaining 159.95 points (0.32%) to close at 49,686.12, buoyed by strength in financials, energy, and consumer staples. Conversely, the tech-heavy Nasdaq Composite retreated 113.41 points (-0.43%) to 26,111.73, while the S&P 500 edged lower by 5.45 points (-0.07%) to 7,403.05. The session was defined by early optimism regarding a potential U.S.-Iran peace proposal, which initially pressured oil prices, only for those gains to evaporate as reports emerged that negotiations remained far apart. This volatility in energy markets, combined with continued selling pressure in semiconductors following Friday’s decline, capped gains for the broader market.

Despite the headwinds in technology, the broader market demonstrated resilience through rotational buying. While the Information Technology sector led losses, seven of the eleven S&P 500 sectors finished higher. The S&P 500 Equal Weighted Index outperformed its market-cap-weighted counterpart by a significant margin, finishing up 0.6% compared to the index’s slight decline, signaling that breadth was improving even as mega-cap leadership faltered. Investors are now pivoting their focus toward NVIDIA’s upcoming earnings report, viewing it as a critical catalyst that could either reaccelerate the AI trade or confirm a shift in momentum. The session highlighted a market increasingly sensitive to interest rate expectations and oil price fluctuations, with the “narrow leadership” of recent weeks facing a test of broader participation.

Key Earnings & Movers

* Seagate Technology (STX): -6.91% ($740.50). Underperformed after the CEO stated that building new factories “would take too long” to meet surging memory demand.
* Lumentum (LITE): -8.83% ($884.98). The worst performer in the sector, dragging down related electrical product names.
* Vertiv (VRT): -8.41% ($339.73). Retreated alongside semiconductor and electrical product weakness.
* Tesla (TSLA): -2.88% ($410.06). Provided weak leadership for the consumer discretionary sector.
* FactSet (FDS): +5.54% ($224.35). A standout gainer in the financials sector, supporting the broader sector gain.
* NVIDIA (NVDA): -1.31% ($222.36). Slight decline ahead of its earnings report later in the week, which is viewed as a pivotal event for the AI trade.
* HIVE Digital Technologies (HIVE): Soared (Price not specified in update, but described as “soaring”). Announced a CAD $3.5 billion AI gigafactory plan in the Greater Toronto Area.
* Regeneron (REGN): Plunged (Price not specified). Phase 3 melanoma trial failed to meet the primary endpoint for progression-free survival.

Stock Spotlight

Regeneron Pharmaceuticals (REGN)
Regeneron experienced a sharp sell-off after its Phase 3 clinical trial for the combination of fianlimab and cemiplimab in metastatic melanoma failed to achieve statistical significance on the primary endpoint of progression-free survival compared to pembrolizumab monotherapy. While the high-dose arm showed a promising numeric improvement in median progression-free survival (11.5 months vs. 6.4 months), it narrowly missed conventional statistical thresholds. Analysts note that while the lack of new safety signals and an ongoing head-to-head Phase 3 study against Opdualag leave a path forward, the market reacted negatively to the “close but not definitive” result. This disappointment frames the readout as mixed rather than a clear win for a potential new immuno-oncology platform, raising concerns about the regulatory and commercial path against established competitors like Keytruda.

Bond Market & Treasuries

U.S. Treasuries faced modest selling pressure throughout the session, unable to build on early strength due to oil volatility and geopolitical uncertainty. The yield curve saw a slight steepening at the short end, with yields moving higher across the board.
* 2-Year Note: Yield settled at 4.09% (+1 basis point).
* 10-Year Note: Yield settled at 4.62% (+3 basis points).
* 30-Year Bond: Yield settled at 5.15% (+2 basis points).

The bond market remains sensitive to inflation concerns and the potential for the Federal Reserve to keep rates restrictive or even hike them, with futures implying a 58.9% probability of a rate hike by January 2027. The market also reacted to reports regarding Iran, where initial hopes of suspended sanctions briefly boosted bond prices before fading as negotiations stalled.

Commodities

* Crude Oil (WTI): Settled at $108.75 per barrel, up $3.26 (+3.1%). Oil experienced high volatility, initially dropping on peace proposal rumors before surging as those hopes faded. Prices moved lower late in the session after President Trump announced a hold on planned military strikes.
* Gold: -0.1% to $4,558.30 per ounce.
* Copper: +0.2% to $6.31 per pound.

Overseas Markets

* Asia & Europe: The provided text notes that the market briefing includes summaries of Asian and European equity and foreign exchange activity, but specific index levels or percentage changes for these regions are not included in the source data.
* FX Rates:
* USD/JPY: 158.89 (+0.1%).
* EUR/USD: 1.1649 (+0.2%).
* GBP/USD: 1.3424 (+0.8%).
* USD/CNH: 6.7998 (-0.2%).

Economic Data

* NAHB Housing Market Index: Rose to 37 in May, beating the Briefing.com consensus of 34 and improving from 34 in April. This suggests a slight stabilization in the housing sentiment despite high mortgage rates.
* China Data (April):
* Retail Sales: +0.2% year-over-year (missed expectations of 2.0%).
* Industrial Production: +4.1% year-over-year (missed expectations of 6.0%).
* Fixed Asset Investment: -1.6% year-over-year (missed expectations of +1.7%).

* Other Global Data:
* Singapore Trade Surplus: Reached SGD 13.068 billion.
* Swiss Q1 GDP: Expanded 0.5% quarter-over-quarter.
* Italy Trade Surplus: EUR 4.709 billion (missed expectations).

Looking Ahead

* Earnings: The market’s primary focus shifts to NVIDIA (NVDA) earnings later this week. This report is expected to be a major determinant for the future momentum of the AI trade and the broader technology sector.
* Data Releases:
* Pending Home Sales (April): Scheduled for 10:00 ET. Consensus expects a 1.6% increase, following a 1.5% prior print.
* Geopolitics: Continued monitoring of U.S.-Iran negotiations and oil supply dynamics, as the situation remains fluid and capable of driving volatility in both energy and equity markets.
* Macro: Investors will remain attentive to Treasury yields, specifically the 10-year note, as a gauge for inflation expectations and Fed policy trajectory.
