SOITEC Stock: Over 38% Drop This Week Following Disappointing Results
This week has been particularly turbulent for Soitec, marked by a sharp correction in the stock market. The semiconductor materials specialist recorded the largest decline in the SBF 120 against the backdrop of its half-yearly publication and announcements deemed unsatisfactory. This dynamic occurred in an already unfavorable market environment, illustrated by the more moderate decline of the main indices.
Significant Drop in Soitec's Stock
Over the past period, Soitec's stock plummeted by 38.72%, closing on Friday evening at 23.30 euros. This is its lowest level since January 2017, significantly outpacing the declines seen in the CAC 40 and SBF 120, which fell by 3.04% and 2.98% respectively over the same period. This major correction brings the annual performance of the stock to -63.31%, a decline that continues a difficult year for the Grenoble-based company. The stock began the week around 37.17 euros, before accelerating its decline from November 20, showing a loss of 30% in a single session, amid high trading volumes. With this dynamic, Soitec holds the position of the strongest decline in the SBF 120 since the beginning of the year, with the exception of Worldline. This movement reflects increased skepticism towards the stock, in a tense sectoral context for European semiconductor players.
Factors Behind the Stock's Deterioration
The deterioration of the stock is largely explained by the publication of the 2025-2026 half-year financial report, following which Soitec reported a turnover of 231 million euros for the semester, down by 32% year-on-year. While this sales level meets consensus expectations, the drop is significant and directly impacts profitability: the gross operating income stands at 79 million euros, a decline of 30%, and the net profit turns negative, at -67 million euros, a situation not seen for ten years for the company. Additionally, the communication of prospects deemed insufficient by analysts adds to the concerns: Soitec expects growth of between 5% and 9% for the current quarter, whereas the consensus had anticipated about 24%. The management also announced the continuation of investment cuts and a significant inventory reduction plan starting the second semester, to adjust production capacity to a demand perceived as weaker. These signals have amplified volatility and reinforced selling pressure on the stock. Finally, the market has taken note of the upcoming departure of the CEO, scheduled for April 2026, which adds to the uncertainty about the strategic trajectory, even though this information has been known since early October.
Technical Perspective on Soitec's Fall
From a technical standpoint, Soitec's fall brings the stock to its major support level of 23.30 euros, a threshold tested during the session and now the closing level. Volatility remains high over a month, at nearly 38%, reflecting broad and sudden movements. Indicators are in zones traditionally associated with strong bearish pressures: the RSI, at 14, signals a largely negative dynamic, while the MACD line remains in negative territory, indicating an unfavorable short-term trend. The stock is now significantly below its moving averages, both on 50 days (38.65 euros) and 200 days (45.11 euros). The Bollinger bands are diverging, with a floor around 27.23 euros, reflecting the extent of recent movements. Finally, the stock's low correlation with the market, illustrated by a negative beta (-0.22), highlights the unique behavior of Soitec's stock over the past period.
