Evidence behind the moves
Pacira BioSciences, Inc. (PCRX) +44.40%

argenx SE (ARGX) -11.83%
argenx said it would discontinue its Phase 3 UNITY study in Sjögren’s disease after an independent committee recommended stopping it for futility. The setback removed a late-stage development opportunity at a large commercial biotechnology company.

Haemonetics Corporation (HAE) +17.46%
Haemonetics disclosed that CSL expects to roll out its plasma-collection devices and disposables to all current U.S. CSL plasma centers by the end of 2027. The expanded expected deployment gives a material customer agreement a much broader potential scope.

Chipotle Mexican Grill, Inc. (CMG) +6.21%
Shares rose after a Financial Times report that Starbucks had explored a potential Chipotle takeover. No agreed transaction was announced. An unconfirmed takeover report moved a major restaurant chain on exceptionally heavy trading.
Sources: dated closing quote and volume · corroborating reporting; proposal unconfirmed
Oracle Corporation (ORCL) -5.48%
Oracle fell amid the AI-stock selloff. Reporting also focused on gas-pipeline delays affecting its Project Jupiter data-center plans; the relative contribution of those concerns to the closing move is unverified. The decline involved a major AI-computing provider and more than $5.75 billion in estimated session dollar volume.

PepsiCo, Inc. (PEP) +3.73%
PepsiCo reported third-quarter results and updated its 2026 outlook; its shares gained despite a reduced profit-growth forecast. The positive closing reaction to mixed earnings and guidance made the consumer-staples bellwether notable.

Accenture plc (ACN) +5.96%
Accenture and Dell announced an expanded collaboration, including an Accenture Dell Business Group focused on private AI and infrastructure modernization. The large consulting-company gain stood out on a day when the broader technology sector declined.
Sources: dated closing quote, volume and market cap · primary collaboration announcement
Applied Optoelectronics, Inc. (AAOI) -13.58%
Optical and AI-infrastructure suppliers sold off as investors reacted to reporting that OpenAI’s annualized revenue was about $20 billion below an earlier reported figure. No company-specific trigger was established. A double-digit decline on heavy volume made it a conspicuous example of the optical-supplier selloff.
