Premarket movers reflected a mix of company-specific catalysts and shifting macro expectations across chips, energy and biotech. Memory stocks broadly gained after a major chipmaking debut in Shanghai, while oil-related names edged lower following a temporary pause in U.S.-Iran tensions. Elsewhere, Forte Biosciences surged on an announced acquisition, and Baker Hughes rose after posting stronger-than-expected quarterly results.
Investors also looked ahead to upcoming earnings from semiconductor packaging and testing peers, and continued to bid up quantum and AI-adjacent themes after a new partnership involving D-Wave.
Key takeaways
- Memory stocks rose: Shares of SK Hynix, SanDisk and Micron advanced in premarket as momentum followed CXMT’s Shanghai listing.
- Energy shares fell: Chevron and ExxonMobil declined after news that the U.S. and Iran agreed to pause attacks, at least for now.
- Biotech deal lifted Forte: Forte Biosciences jumped more than 39% on a reported acquisition offer from Argenx.
- Results drove Baker Hughes higher: Baker Hughes gained nearly 2.2% after reporting better-than-expected earnings and revenue.
- Semiconductors and quantum stayed in focus: Amkor climbed ahead of its next report, while D-Wave surged on a partnership with AT&T.
Semiconductor strength extends from a Shanghai debut
Memory-related shares rose broadly in premarket, tracking the momentum from chipmaker CXMT’s public market debut in Shanghai. CNBC reported that CXMT’s stock surged more than 466% after the listing, and that the rally carried into U.S.-listed memory names.
In that group, SK Hynix climbed 4.7% and SanDisk rose 3.6% in premarket trading, while Micron Technology added 2.5%. The reaction suggests investors are positioning for improved sentiment around memory demand and supply dynamics—an area that remains highly sensitive to the outlook for electronics, data-center spending and overall semiconductor cycles.
For market participants, the more immediate takeaway is that the move appears sentiment-driven: the gains are less about new company guidance from the U.S. memory names and more about contagion from a high-profile listing that has drawn attention back to the sector.
Energy stocks soften on a temporary de-escalation
Energy equities traded lower as oil prices slipped following a reported pause in hostilities. CNBC said the U.S. and Iran agreed to pause attacks “for now,” which reduced the perceived near-term risk premium embedded in crude.
Chevron fell 2.7% and ExxonMobil declined 3.2% in premarket trading. Additional weakness was visible across domestic producers, with APA, Devon Energy and Diamondback Energy each down around 4%.
The market implication is straightforward: with the immediate geopolitical threat dialed back, investors appeared more willing to trim energy exposure ahead of any next developments. Still, the language around a “pause” leaves room for volatility if conditions change.
Forte Biosciences surges on Argenx acquisition terms
Forte Biosciences shares jumped more than 39% in premarket after the company said it will be acquired by Argenx. CNBC reported that the transaction values Forte at $2.2 billion in cash, or $77 per share.
The reported offer represents a 40% premium over Forte’s closing price of $54.78 on Friday. CNBC also noted that U.S.-listed shares of Argenx were down marginally in premarket trading, indicating the market may be focused on deal mechanics and the cost of acquiring the target rather than immediately rewarding the buyer.
With the deal expected to close in the third quarter, investors will likely watch for regulatory review, any required approvals and management commentary on how the acquisition fits Argenx’s pipeline strategy. Premarket market pricing can shift quickly if there are signals about timing, financing, or deal conditions.
Baker Hughes rises after a stronger quarter
Baker Hughes gained nearly 2.2% in premarket after reporting better-than-expected earnings and revenue for the second quarter, according to CNBC. The company’s management cited underlying fundamentals and its ability to manage through Middle East uncertainty while discussing its full-year outlook.
CNBC reported that Chief Executive Lorenzo Simonelli said Baker Hughes expects to reach the midpoint of its full-year guidance, aided by “favorable underlying fundamentals,” while continuing to navigate regional uncertainty.
The implication for investors is that the firm is seeking to preserve its earnings trajectory despite persistent macro and geopolitical risks that can affect drilling activity and project timelines. The next question for the market is whether the guidance midpoint remains achievable as conditions evolve and as investors assess whether the quarter reflects durable demand or temporary strength.
Semiconductor and quantum headlines ahead of catalysts
Amkor Technology rose more than 2.4% as the semiconductor packaging and testing provider prepared to report its next quarterly results after the bell. Investors typically use pre-earnings positioning to gauge near-term margins, customer digestion of semiconductor orders and any signs of recovery or weakening in end-market demand.
In quantum-related trading, D-Wave jumped more than 7% after announcing a partnership with AT&T. CNBC reported that the company plans to use its annealing quantum computers to support the telecom giant’s AI efforts. Quantum-focused shares also moved higher, with IonQ rising nearly 4.5% and Rigetti Computing gaining 3.8% in premarket.
While these moves are driven by headline linkage to AI initiatives, investors will likely focus on whether partnerships translate into measurable commercial progress over time. Near-term price action in high-beta themes can be especially sensitive to incremental news and broader risk appetite.
Heading into the next session, investors will be watching for follow-through from memory and energy trades, as well as any early read-through on acquisition sentiment tied to Forte and Argenx. With several catalysts on the calendar—particularly Amkor’s after-bell earnings and the broader stream of corporate updates—market direction may hinge on whether fundamentals and guidance comments align with the momentum implied by premarket moves.
