Bouygues stock abandons the €42 threshold, under pressure

Support at €42.61 broken through, three moving averages in resistance above price

Early in the afternoon, Bouygues loses 1.81% to €41.84, after breaking through its support level at €42.61 during the session. The stock remains below this level, which constitutes a notable technical breakdown. Three moving averages weigh down above: the 20-day MA at €43.85 (difference of -4.58%), the 50-day MA at €45.87 (-8.79%) and the 200-day MA at €48.10 (-13.01%) form a tiered ceiling that the price has failed to regain for several weeks.

The RSI at 33 approaches the oversold zone without reaching it clearly, reflecting progressive exhaustion without a reversal signal. Vinci and Eiffage, comparable sector values, are declining by 1.57% and 1.90% respectively, indicating common pressure on French construction companies in this session. The CAC 40 is down 0.58% during the session.

A quarterly decline of nearly 14% in a construction sector under strain

Over three months, Bouygues is down 13.87%, erasing a large portion of the annual gain which remains positive at +9.19%. The medium-term momentum weighs on a value exposed to a clearly degraded construction cycle: in September 2026, the construction climate in France stands at -17.2 according to Eurostat-ECFIN data, residential building permits are declining by 9.5% over twelve months and contracts concluded in public works are plunging by 27.6% over three months. When publishing first half 2026 results on July 31, the group confirmed its intention to stabilize revenue at constant exchange rates and maintain its operating result at a historically high level. The next resistance level is located at €46.70, representing a difference of more than 11% above the current price.
