The model's market view
US equities are modestly higher with AI infrastructure and hardware names leading after strong updates from SpaceX and Super Micro. The S&P 500 is grinding higher but macro headwinds from elevated oil prices and a 5% 10-year Treasury yield are capping broad upside. The AI trade has regained momentum, favoring high-beta infrastructure suppliers over the broad index for a one-session horizon.
Why each pick
SPCX
SpaceX reported Q3 results ahead of expectations and confirmed it has formed special committees with Tesla to evaluate a potential merger, a powerful one-day catalyst. The stock is up roughly 8-10% intraday and is the clear leader in the AI/space theme; momentum and short covering could extend. Risks: merger talks may prove preliminary, the stock is a recent IPO with high volatility, and a gap-up of this size can invite profit-taking. Reference price is a delayed intraday quote via eToro.
SMCI
Super Micro raised fiscal Q1 revenue guidance to $18.5–19.5 billion from $14.5–15.5 billion and lifted gross margin guidance, signaling AI server demand remains far stronger than feared. The stock is up over 12% and could see analyst upgrades during the session. Risks: the update is preliminary, the name is highly volatile, and competition in AI servers is intense. Reference price is a delayed intraday quote via eToro.
VRT
Vertiv is a direct beneficiary of AI data-center buildout through power and cooling infrastructure, and it is participating in the AI hardware rally without relying on a single earnings surprise. Its fundamental exposure to rising rack density and liquid cooling supports a durable growth narrative. Risks: valuation is elevated, and industrial capex could slow if AI spending moderates. Reference price is a delayed intraday quote via eToro.
MU
Micron is riding the memory upcycle driven by AI training and inference demand, and recent disclosures of a large billionaire stake add a sentiment tailwind. The stock is up about 2-3% and tends to be less gap-driven than SMCI, offering a steadier way to play the AI hardware theme. Risks: memory remains cyclical, and China competition and pricing pressure could resurface. Reference price is a delayed intraday quote via eToro.
NBIS
Nebius is rebounding as Elon Musk dismissed AI overcapacity concerns, reversing last week's selloff in AI cloud names. The company can sell all of next year's GPU capacity, and the stock's high beta means it can outperform SPY if risk appetite holds. Risks: the AI cloud space is crowded, financing needs are significant, and the stock remains volatile after a sharp drawdown. Reference price is a delayed intraday quote via eToro.
