Management raised its 2026 revenue growth outlook to 7–9% from 5–7%, raised its adjusted operating margin forecast to 27–28%, and doubled its share-repurchase target. These improvements gave investors a strong reason to revalue the stock.
Charles River Laboratories Jumps 15% after Analyst Day
On October 21, analysts responded positively to the company's refreshed strategic plan, with multiple major banks raising their price targets while maintaining bullish ratings.
The plan targets 5–7% organic revenue growth annually from 2027–2030, margin expansion toward 24%, low-double-digit EPS growth, and more than $300 million in expected cost savings. The company also highlighted its cell and gene therapy capabilities and laboratory automation initiatives. AI-assisted drug discovery was another potential tailwind.

Allegion reported Q3 revenue of $1.173 billion, up 9.6%, and adjusted EPS of $2.60, up 13% year over year. Growth was led by its Americas non-residential business.
It raised its full-year 2026 adjusted EPS outlook to $9.05–$9.10. On October 23, Bank of America upgraded the shares to Buy from Neutral and increased its price target to $200 from $164, citing stronger growth momentum in the Americas.
CrowdStrike Surges 13% on Expanded NVIDIA Partnership
On October 21, CrowdStrike and NVIDIA announced an expanded collaboration to extend AI-agent security across software and silicon. The announcement strengthened the investment case for protecting enterprise AI systems as adoption grows.
On October 22, an analyst also raised a price target from $250 to $275, citing encouraging early feedback on CrowdStrike's AI detection and response offerings. These developments were identified as likely contributors to the late-week surge.
Paramount Skydance Jumps 12% on Potential SpaceX Investment
The key headline on October 21 was commentary from media investor John Malone suggesting SpaceX could invest $8–10 billion in Skydance, potentially alongside a global content-output agreement.
The remarks fueled speculation that a transaction could help reduce Skydance's debt. However, Malone did not confirm that negotiations were underway. The stock was also recovering after a sharp post-distribution adjustment related to warrants issued to shareholders in October.
HP Inc. Rises 12% on Renewed Interest in AI PCs and Workstations
HP's rebound appears to reflect renewed investor interest in its AI-capable PCs and workstation products, including systems built around NVIDIA's advanced computing technology.
Its August fiscal Q3 results had already shown revenue growth of 12.5% to $15.7 billion. The October move was interpreted as renewed confidence in its higher-end AI hardware strategy, combined with a rebound in hardware-sector sentiment. However, no single definitive announcement has been established as the cause of the full week's gain.
ServiceNow Rises 12% on New AI-Security Product and Analyst Upgrades
ServiceNow introduced AI Passport, designed to give enterprise AI agents secure digital identities and control over the data they can access and actions they can perform.
Mizuho and TD Cowen also raised their price targets, citing expectations for strong quarterly results, AI adoption, software cross-selling, and government contracts. The company denied reports that it was pursuing an acquisition of customer-service AI startup Decagon, saying it saw no major strategic gaps requiring large acquisitions.
