Dassault Aviation Share: 8% Lost in Three Months, Stock Slides Further by 2.5%

A Decline That Isolates Dassault Aviation in a Rising SBF 120

The Dassault Aviation share loses 2.29% to €281.80 during the session, compared to €288.40 at the previous close, while the SBF 120 gains 0.46% and the CAC 40 rises 0.4%. The stock is among the steepest declines in the index, in the wake of a sector offering no support: Thales falls 2.16% while Safran gains 0.21%. Over the week, the decline reaches 3.1%, recovering most of what the stock had regained over one month (+1.59%).

In the preceding days, the agreement with the AED Portugal cluster, signed as part of the Rafale campaign for Portugal's F-16 fleet renewal, was dated September 24. In H1 2026, published July 22, the group displayed an order book of €45.4 billion, compared to €46.6 billion a year earlier.

Below Its Three Moving Averages, the Stock Approaches Its Support at €275.40

The price is below its MA20 (€286.73, gap of 1.72%), its MA50 and its MA200 (€306.15), which remains nearly 8% above. The stock is thus approaching its support at €275.40, approximately 2.3% below the current price, while the RSI at 49 remains neutral. The distance to the MA200 tells mainly of a medium-term decline: the stock is still down nearly 8% over three months.

On the management side, Igor Alexandre Gauffreteau is a member of the executive board and chief executive officer. Should the support at €275.40 give way, the resistance at €294 would remain the closest bullish reference point.
