Why It’s Moving

Roblox Shares Slide Despite Q3 Beat as User Engagement Metrics Decline
- Third-quarter bookings exceeded the high end of company guidance, supported by stronger retention among adult users and game creators, while the net loss narrowed to $0.32 per share compared to the consensus estimate of a $0.41 loss.
- Daily active users fell 9% to 138 million and engagement hours dropped 15% to 34 billion, signaling growing pains following the rollout of tougher child-safety measures that impacted user activity.
- CEO David Baszucki highlighted an explosion of AI-fueled content with game volume leveraging artificial intelligence growing 50% quarter over quarter, though this innovation surge did not offset the immediate negative market reaction to declining user metrics.

Corning's AI-Driven Surge Faces Analyst Scrutiny Despite Strong Q3 Optical Growth
- Third-quarter sales rose 19% year over year to $5.1 billion, with enterprise optical sales quadrupling to reach a $6 billion run rate, signaling sustained strength in AI infrastructure demand.
- Despite the operational beat, Corning was cited as a top detractor from relative performance in multiple income and growth equity portfolios during the third quarter, contrasting with its 44% year-to-date return that has outpaced major tech peers.
- Management projects approximately 36% growth in adjusted earnings per share for the fourth quarter, following a similar 36% increase in the third quarter, though analysts remain cautious about valuation risks.
