Saint-Gobain Shares Drop 2% and Lose Resistance at €79.76

The stock is among the biggest declines in the CAC 40 in early afternoon

Saint-Gobain shares drop 2.01% to €78.98, down from a last close at €80.60. The decline places the stock among the biggest losses in the CAC 40, following Vinci (-2.38%), EssilorLuxottica (-2.08%), and Eiffage (-1.96%): the entire construction sector is under pressure, while the Parisian index falls by 0.2% and the SBF 120 loses 0.15%. The movement follows a marked bullish sequence, with a gain of over 14% over three months.

The session on June 25 had already seen the stock in the top three of the CAC 40, and the session on June 24 had confirmed the breaking of the resistance at €79.76, as detailed in the session of June 24. Today's decline brings the price below this threshold and resembles profit-taking after a rally fueled by a series of strategic divestments (Dahl in the Nordic countries sold to Kesko in mid-June, HKO in early June).

The stock remains above its short-term averages but struggles against the MM200 at €82.30

Despite the decline, the stock remains 1.92% above the MM20 (€77.49) and 2.24% above the MM50 (€77.25). The longer outlook remains constrained: the MM200 peaks at €82.30, which is 4% above the current price, and represents the next technical hurdle. The RSI at 58 remains in the neutral zone, which leaves room before returning to extreme boundaries.

The reference support is identified at €73.02, resistance at €81.76. The performance over one year remains negative at -21.88%, reminding that the spring rebound has not yet offset the drop in the second half of 2025. The next key event on the calendar is the general meeting scheduled for July 4, 2026.
