Shares moved broadly in premarket trading as a wave of earnings and forward-looking guidance cut through investor focus on growth, margins and outlooks. Biotechnology, industrial and semiconductor names led the upside after results beat expectations or guidance improved, while payments and parts of the real estate, power and semiconductors sectors slipped on softer forecasts and missed revenue targets.
Key takeaways
- Biogen shares rose as the company reported stronger-than-expected revenue and raised full-year adjusted EPS guidance.
- Vertiv fell after results beat expectations, but organic revenue growth for the year lagged analyst consensus.
- Generac gained on better-than-expected earnings and reiteration of its revenue growth outlook.
- CoStar slid as revenue missed estimates and current-quarter sales guidance came in below consensus.
- Visa dropped following a fiscal 2026 guidance update that was viewed as less robust than expected.
What drove the market moves
Company-specific disclosures accounted for most of the premarket action, with investors reacting to both quarterly performance and changes to forward guidance.
- Revenue beats and raised guidance supported upside: Biogen advanced after beating Wall Street consensus on revenue and lifting its full-year adjusted EPS outlook. General Dynamics also gained after topping consensus estimates on both revenue and earnings per share, and citing a backlog of $136.5 billion. Seagate rose after issuing an outlook that exceeded analysts’ expectations, with shares of Western Digital moving higher “in sympathy.” Manhattan Associates jumped after second-quarter earnings and revenue topped expectations and full-year profit and revenue forecasts were raised.
- Mixed results with growth that didn’t meet expectations pressured shares: Vertiv fell despite beating earnings and revenue expectations, as its year-on-year organic growth rate of 17.8% was below FactSet’s 23.6% consensus.
- Earnings and guidance, not just headlines, mattered for power and industrial demand: Generac rallied on better-than-expected second-quarter earnings per share and reaffirmed revenue growth guidance for the year. PPG Industries slipped after adjusted EBITDA and earnings per share missed estimates, though it reaffirmed full-year earnings guidance.
- Guidance disappointments weighed on semiconductors and payments: KLA moved lower after issuing guidance investors viewed as underwhelming. Visa fell after fiscal 2026 guidance underwhelmed the Street, even as the company reaffirmed mid-teens adjusted nominal dollar EPS growth (the article noted the consensus expectation). Skyworks Solutions dropped on a narrow margin miss and fourth-quarter EPS guidance that came slightly below consensus.
Market reaction across key sectors
Investors separated “beat-and-raise” stories from “beat but not enough” and “guidance not compelling” narratives, creating a split across sectors.
- Healthcare and defense held up: GE HealthCare Technologies rose after reporting second-quarter adjusted earnings per share above consensus and reaffirming full-year 2026 earnings guidance. General Dynamics also climbed following a stronger-than-expected quarter and robust backlog.
- Consumer and real estate saw downside: Procter & Gamble shares fell after quarterly revenue missed analyst expectations, with net income declining year over year. CoStar dropped sharply following second-quarter revenue that failed to meet expectations and a weaker current-quarter revenue outlook than consensus.
- Auto and industrial equipment reflected earnings plus outlook sensitivity: Ford surged after adjusted earnings beat expectations and the company increased its 2026 earnings outlook, though automotive revenue came in slightly below LSEG expectations. Teradyne rose after second-quarter results and third-quarter profit and sales forecasts topped estimates, according to FactSet.
- Payments and enterprise software diverged: Visa slid on its 2026 guidance. By contrast, supply chain software provider Manhattan Associates rose on earnings and revenue beats and raised full-year forecasts.
What investors are likely watching next
The premarket tape underscored that forward guidance and growth quality are currently driving stock reactions as much as headline earnings. With multiple companies raising or narrowing their outlooks, traders will likely focus on consistency between reported performance and future demand signals.
Investors should watch for additional guidance updates in the ongoing earnings cycle, along with upcoming macro catalysts that can influence valuations—particularly interest-rate expectations and inflation-sensitive data points that affect discount rates and consumer spending outlooks. Further scrutiny will also fall on margin sustainability, especially for semiconductor and payments companies, where small deltas in forecasts can translate into larger market moves.
