Stock Market Update

[BRIEFING.COM] The S&P 500 (+0.3%), Nasdaq Composite (+0.6%), and DJIA (-0.2%) trade in a stable range just after midday. Stocks have given back some of their opening strength, though a solid rebound across semiconductor names still underpins the mostly higher standing of the major averages.

The PHLX Semiconductor Index is up 1.9%, with AI infrastructure names such as Lumentum (LITE 783.69, +50.87, +6.94%) and Teradyne (TER 339.19, +16.84, +5.22%) posting some of the widest gains. Memory names such as Micron (MU 888.60, +39.65, +4.67%) are also outperforming after Bloomberg reported that Kimi K3, the latest model from Chinese company Moonshot AI that added pressure across semiconductor stocks last week, requires a large amount of memory to operate.

Advanced Micro Devices (AMD 509.11, +13.35, +2.69%) is a standout among large chipmakers after news that Microsoft (MSFT 401.79, +7.97, +2.02%) will deploy AMD's Helios Rackscale Solution for frontier-model AI inference, while Azure will add two EPYC "Venice"-powered VM series and broaden its deployment of Pensando DPUs. AMD will begin shipping Helios to customers, including Microsoft, in 2H26.

The information technology sector (+0.6%) is off its earlier session highs, with some pressure in some of its largest non-chipmaker components such as Apple (AAPL 324.35, -9.39, -2.81%) and Oracle (ORCL 122.49, -3.92, -3.10%) limiting the gains.

Overall, the mega-cap complex tilts higher, with the Vanguard Mega Cap Growth ETF up 0.5%. Alphabet (GOOG 354.27, +8.15, +2.35%) is a standout ahead of its earnings release later this week, helping the communication services sector (+1.5%) outperform.

Elsewhere, the energy sector (+1.1%) also outperforms after what was a somewhat choppy morning for oil prices. News of an increasingly deadly exchange of fire between the U.S. and Iran has been somewhat tempered by headlines of intermediaries becoming involved in negotiations. Crude oil is currently flat at $81.78 per barrel.

Market breadth has deteriorated since this morning's relatively strong open, with seven S&P 500 sectors now trading lower. However, the losses are relatively modest in nature. The defensive consumer staples (-0.8%), utilities (-0.7%), and health care (-0.6%) sectors are among the laggards as investors rotate back into semiconductor names today.

Although participation has narrowed since the open, the major averages remain mostly higher as semiconductor stocks attract solid buying interest following last week's retreat. Trading has settled into a relatively narrow range amid a light corporate news calendar, with investors looking ahead to a consequential slate of earnings reports later this week.
