Séché Environnement Stock Soars 33% in 5 Weeks, Despite Overbought RSI

Technical Indicators Point to Strong Upward Momentum

Breaking the €73.50 monthly reference mark, combined with a weekly increase exceeding 12%, places the stock in a configuration where several indicators align. Over the span of five weeks, the stock has rebounded nearly 33% from its early February 2026 low of €55.60, gradually erasing the correction begun at the end of the previous year. Technically, the price has significantly crossed the 50-day moving average, set at €69.48, which is a positive momentum signal. The RSI stands at 74, in overbought territory, reflecting the magnitude and speed of the recovery movement. The upper Bollinger band, at €72.15, has also been exceeded, confirming the exceptional nature of the recent progress. The next identified resistance is at €80.80, while the long-term support is positioned at €57.00.

Fundamental Context Provides Additional Insight

The fundamental context offers further illumination. On March 10, 2026, the day after the annual results were published, Oddo BHF revised its price target from €100.00 to €90.00, while maintaining an 'outperform' recommendation. This revision did not halt the bullish movement: the stock had then advanced nearly 4% in session, starting the sequence of gains that continues to this day. The implicit discount relative to Oddo BHF's target remains significant—about 21% below the targeted €90.00—placing the current level well below the analyst's target despite recent progress. Noteworthy on the calendar: the 2026 general assembly is scheduled for April 24. Over the past twelve months, the stock's performance remains negative at -2.12%, indicating that the ongoing recovery has not yet fully compensated for the correction over the past year.
