Tuesday’s trading session kicked off September with downward momentum across Wall Street. Equity futures trended lower as climbing bond yields dampened investor sentiment and triggered a pullback from riskier assets.
The month of September carries a historically bearish reputation for the S&P 500, and Tuesday’s opening action reinforced that seasonal trend.
Novartis Soars on Positive Multiple Sclerosis Trial Data
Novartis emerged as Tuesday’s top performer, with shares jumping between 4% and 4.5%. The pharmaceutical giant from Switzerland revealed that remibrutinib, its oral BTK inhibitor medication, successfully achieved primary endpoints across two separate Phase III clinical trials focused on relapsing multiple sclerosis treatment.
The clinical trials, designated REMODEL-1 and REMODEL-2, demonstrated that remibrutinib successfully lowered annualized relapse rates when compared against teriflunomide. Additional positive outcomes included enhanced MRI brain lesion reduction and postponed disability progression in patients.
The company intends to showcase this clinical data at the upcoming MSToronto2026 congress while initiating worldwide regulatory submission processes. These gains materialized despite concurrent news that Novartis suspended eight clinical trials involving its experimental CAR-T therapy, Rap-cel, following the deaths of three patients from serious immune reactions in late August.
Robinhood emerged as another positive performer Tuesday. The trading platform’s shares increased 2.3% to reach $107.22 following Morgan Stanley’s decision to upgrade the stock to Overweight status while elevating its price target from $124 to $150. The investment bank highlighted enhanced product features and stronger financial performance from the company’s current user base.
Chip and AI Stocks Retreat Amid Higher Yields
Semiconductor and artificial intelligence stocks encountered significant selling pressure during premarket hours. Sandisk experienced a 3.2% decline, with Marvell, Intel, and Corning similarly trending downward.
Market participants retreated from risk-oriented investments as treasury yields advanced, creating headwinds specifically for growth-focused technology equities.
NIO shares decreased approximately 4% in anticipation of the company’s forthcoming Q2 financial results. The decline occurred despite the Chinese electric vehicle manufacturer announcing a 14.5% year-over-year improvement in August deliveries, which totaled 35,836 vehicles.
The August delivery figures comprised 21,174 vehicles from the primary NIO brand, alongside 8,810 units from the ONVO sub-brand, and 5,852 from FIREFLY. The marginal sequential decrease from July’s 35,934 vehicle deliveries seemed to negatively influence investor sentiment.
Metallus shares also retreated roughly 3% following the company’s announcement that CEO Michael S. Williams plans to retire effective December 31, 2026. President and COO Kris R. Westbrooks has been designated to assume the CEO position beginning January 1, 2027. Williams will continue serving in an advisory capacity through June 2027.
Multiple corporations are scheduled to release quarterly earnings following Tuesday’s market close. The reporting companies include Palo Alto Networks, Dell, Credo, and MongoDB.
Investors will be monitoring these financial reports attentively as they seek guidance for navigating the remainder of September’s trading sessions.
