Dassault Systèmes stock closed the last completed U.S. session on the OTC market at a level that left the shares little changed in percent terms versus the prior close on that venue on September 21, 2026. Compared with a major U.S. benchmark index, the U.S.-listed shares underperformed slightly in percent terms, indicating a relatively softer tone for the stock than for the broader market on that day.
September 21, 2026 in numbers
Dassault Systèmes SE (ISIN FR0014003TT8) traded on the U.S. OTC market within a narrow intraday range on September 21, 2026, with the regular session on U.S. exchanges having run from 9:30 a.m. to 4:00 p.m. ET. The U.S.-listed shares finished the session with a modest percentage move versus the previous OTC close, while the comparison index, taken from the large-cap U.S. market, showed a different percentage change over the same trading day. On its home market Euronext Paris, Dassault Systèmes shares moved in the low-single-digit percent range during their latest completed session, with the official close time stamped shortly after the end of continuous trading, and the difference between the home and U.S. percentage performance primarily reflecting the exchange rate between euros and U.S. dollars, as described by European market coverage from outlets such as Ideal-investisseur.
After the bell on September 21, 2026
After the close on September 21, 2026, Dassault Systèmes stock continued to be available for trading in the U.S. extended session on the OTC market until 8:00 p.m. ET, but no distinct after-hours price move stood out relative to the official regular-session close in percent terms. With no company-specific results release or investor event scheduled immediately after the bell, the stock’s near-term path in U.S. trading is primarily set by broader sector sentiment and overall index moves on the next U.S. trading day, which follows on September 22, 2026, when the regular session again runs from 9:30 a.m. to 4:00 p.m. ET.
