Soitec Stock Rebounds Over 3% Following a 14% Plunge
The Isère-based semiconductor substrate specialist regains ground in mid-session, following the upward trend of the semiconductor sector in Paris. The rebound comes after a sharp drop, as two brokerage houses have just updated their opinions in opposite directions. Volatility remains high on the stock.
Session Marked by Contrasting Analyst Opinions and High Volatility
Soitec stock gains 3.15% to €129.30, among the strongest rises in the SBF 120, just behind STMicroelectronics (+3.78%). This movement comes after a drop of more than 14%, triggered by contrasting analyst revisions. Today's rebound only mitigates a weekly decline of nearly 22%, and a monthly drop of 24.5%. However, the quarterly performance remains impressive at nearly 193%, reflecting a rollercoaster spring for the stock.
The price is still significantly below its 20-day moving average at €157.21 (a gap of -17.75%), indicating that the correction from the last sessions has not been fully absorbed. Conversely, it remains above the MM50 (€123.88) and maintains a cushion of 124% over the MM200, a legacy of the spring rally. The RSI at 43 indicates a neutral climate, with no sign of seller exhaustion. The support identified at €113.10 remains the lower bound to keep in mind in case of a new downturn.
Jefferies and Bernstein Issue Opposing Signals on the Stock
The session unfolds against a backdrop of radically divergent analyst opinions. Jefferies has downgraded its rating to underperform while raising its price target from €45 to €85: the target remains significantly below the current price and implies a theoretical downside potential of about 34%. On the opposite end, Bernstein has issued an outperform rating with a target raised from €150 to €180, representing an appreciation potential of about 39% compared to today's price. This wide gap summarizes the split around the case after the spectacular rally over the last three months.
The fundamental backdrop remains mixed. During the announcement of the annual accounts for 2026 (on May 27, 2026), Soitec highlighted the growing adoption of Photonics-SOI solutions for data centers and market share gains related to AI demand, while pointing out the risk of profitability pressure after a significant production cut. On the short-selling side, two funds cumulatively hold 1.82% of the capital sold short, according to reviewed statements, a sharp decline over thirty days (4.87% a month ago). This easing of short positions signals a gradual covering of bearish positions, without indicating a reversal of conviction by operators.
