Today’s focus on analyst stance
Heading into today’s US session on September 17, 2026, the reiterated Buy rating and unchanged USD 1,215 price target from Jefferies is likely to remain a reference point for investors following Argenx, as highlighted in the September 16, 2026 note by ad hoc news. The rating reaffirmation, combined with the documented gap between the latest close at USD 1,001.50 and the USD 1,215 target, may frame expectations around the stock today even in the absence of a scheduled company-specific event within the immediate trading window.
