Argenx stock closed near USD 990 on the Nasdaq on September 21, 2026, leaving the U.S.-listed shares roughly unchanged in percent terms versus the prior official close around USD 990.32 from September 18, 2026. Compared with the broader market, the stock lagged the Nasdaq Composite, which gained about 2.1 percent on the day as technology names led a strong advance.
September 21, 2026 in numbers
Argenx SE (ISIN NL0010832176, Nasdaq: ARGX) had previously ended the last completed Nasdaq session on September 18, 2026 at USD 990.32, a level that sat comfortably within that day’s trading range and marked a meaningful gain over the start-of-year level near USD 840.95 cited for early 2026 per Ad-hoc-news. On September 21, 2026, the Nasdaq Composite closed around 27,080 points, up roughly 2.1 percent from the prior close of 26,522.55 as a rally in major chipmakers drove a broad advance across growth shares, according to CapitalStreetFX. This left Argenx trailing the day’s technology-led benchmark move in percentage terms.
After the bell and the next trading day
After the close on September 21, 2026, Argenx stock was indicated near its regular-session level in early after-hours trading on Nasdaq, with only marginal price changes reported on U.S. quote pages. Looking ahead, Argenx has scheduled an extraordinary general meeting for September 17, 2026 at 3:00 p.m. local time, a corporate event highlighted in the company’s calendar and noted by MarketScreener, which investors monitor for potential updates on strategic or capital decisions. More broadly, with the Nasdaq recently buoyed by strong performance in large semiconductor names, sector moves in U.S. growth and biotech peers remain a key backdrop for Argenx stock on the next U.S. trading day.
