U.S. equity markets faced headwinds entering September on Tuesday morning. Futures contracts slipped lower as ascending treasury yields dampened investor sentiment and reduced risk-taking appetite.
Historically, September ranks as the S&P 500’s weakest performing month, and Tuesday’s initial trading action aligned with that historical trend.
Novartis Surges Following Multiple Sclerosis Drug Success
Novartis emerged as the session’s top performer, with shares advancing between 4% and 4.5%. The pharmaceutical giant based in Switzerland revealed that remibrutinib, its oral BTK inhibitor medication, successfully achieved primary endpoints across two Phase III clinical studies targeting relapsing multiple sclerosis.
The clinical studies, designated REMODEL-1 and REMODEL-2, demonstrated that remibrutinib successfully lowered annualized relapse rates when compared against teriflunomide. Additional benefits included enhanced MRI brain lesion reduction and postponed disability progression.
The company intends to showcase this clinical data at the MSToronto2026 medical congress and initiate worldwide regulatory submission processes. These positive developments occurred despite separate news that Novartis temporarily halted eight clinical studies examining its experimental CAR-T therapy, Rap-cel, following three patient fatalities from serious immune reactions in late August.
Robinhood represented another positive performer in Tuesday’s session. The stock climbed 2.3% to reach $107.22 after Morgan Stanley elevated its rating to Overweight while increasing the price target from $124 to $150. Analysts highlighted enhanced product features and superior monetization from the company’s current user base.
Chip and Technology Names Retreat as Yields Climb
Stocks in the artificial intelligence and semiconductor sectors encountered downward pressure during premarket hours. Sandisk experienced a 3.2% decline, while Marvell, Intel, and Corning similarly retreated.
Market participants reduced exposure to riskier assets as treasury yields advanced, creating headwinds for growth-focused technology companies.
NIO shares dropped approximately 4% in anticipation of its forthcoming Q2 financial results. This decline occurred despite the electric vehicle manufacturer from China posting a 14.5% year-over-year increase in August vehicle deliveries, reaching a total of 35,836 units.
The August delivery breakdown consisted of 21,174 vehicles from the flagship NIO brand, 8,810 units from the ONVO sub-brand, and 5,852 from FIREFLY. A marginal month-over-month decrease from July’s 35,934 deliveries seemingly affected investor confidence.
Metallus shares also fell roughly 3% following the announcement that CEO Michael S. Williams plans to retire effective December 31, 2026. Current President and COO Kris R. Westbrooks will assume the CEO position beginning January 1, 2027. Williams will continue serving in a special advisory capacity through June 2027.
Multiple corporations are scheduled to release quarterly earnings following Tuesday’s market close. Palo Alto Networks, Dell, Credo, and MongoDB are among those reporting.
Investors will monitor these financial reports attentively as they search for market direction while September trading progresses.
