Soitec Stock Plummets Over 7%, Marking the Worst Performance in the SBF 120
The Isère-based semiconductor substrate specialist sharply erased its previous day's gains. The stock underwent the steepest decline in the broad Paris index, as JP Morgan just lowered its target. The drop occurred in an SBF 120 that was otherwise significantly on the rise.
Soitec Falls 7.24% to €153.70, Lagging Behind the SBF 120 Which Gains 0.87%
Soitec loses 7.24% to €153.70, trailing the SBF 120 which, however, gains 0.87%. Two analyst opinions published on June 2 weigh on the session. JP Morgan lowered its target from €150 to €130, indicating a negative potential of about 15% compared to the current price, while maintaining a neutral opinion. CIC Market Solutions positioned itself at €150, also neutral, a target nearly aligned with today's price. This disagreement on the target illustrates the difficulty in valuing the stock after its spectacular rally: Soitec still shows a gain of +265.9% over three months and +254.1% over a year. Based on the expected earnings per share, the stock is trading at about 513 times the earnings of the current fiscal year and nearly 81 times those of the next, according to the consensus of analysts surveyed. Regarding short positions, two funds cumulatively hold 1.93% of the capital sold short, according to reviewed declarations. The downward pressure has significantly eased over a month: the cumulative reached 4.67% thirty days ago, a decline of 2.74 points. This movement reflects a progressive covering of bearish bets, without however justifying a definitive interpretation of sentiment.
The Stock Falls Below Its 20-Day Moving Average After a Historic Rally
The price falls below the 20-day moving average (MM20) at €160.35, with a negative gap of 4.15%. The decline mechanically erases the rebound from the previous day and brings the stock back to levels already touched in the middle of last week. Longer averages remain far below the price: the 50-day moving average (MM50) is at €114.66 (price 34.05% above) and the 200-day moving average (MM200) at €54.92, evidencing the magnitude of the rally that began in early March. The RSI at 56 does not send a signal of marked exhaustion, which fits with a consolidation movement after a surge rather than a fundamental reversal. The session extends the period of high volatility observed since the annual accounts were published on May 27: a decline of 6% the day before the results, a surge of 20% upon announcement, and then fluctuations beyond €150. As a reminder, during the May 27, 2026 publication, the group highlighted among its opportunities the traction of the AI market and the adoption of Photonics-SOI solutions for data centers, while pointing out the correction of stocks at its RF-SOI clients as the main risk. The next technical marker is at the support level of €98.76, well below the current price.
