Soitec stock climbs and displays +344.5% over one year, boosted by Photonics-SOI
After several volatile sessions marked by sharp pullbacks, Soitec regains momentum this Friday and posts gains in a SBF 120 also oriented upward. The security, which displays a spectacular gain over one year, remains below its resistance level at 146.35 € but maintains a solid lead over its moving averages, demonstrating an intact underlying bullish dynamic despite recent volatility.
A rebound supported by moving averages very substantially exceeded
The Soitec stock gains 1.54% to 138.65 € during the session, ranking among the strongest increases in the SBF 120. This movement occurs in a globally supportive market context, with the CAC 40 advancing 0.55% and the SBF 120 by 0.52% during the session. The security remains nevertheless below its resistance at 146.35 €, which had already weighed on previous sessions and caused notable declines in the preceding days.
The technical configuration remains distinctly bullish. The price is evolving above the MA20 at 120.90 € (gap of +14.68%) and the MA50 at 112.56 € (+23.18%), two moving averages substantially exceeded which reflect the momentum accumulated since the raising of growth forecasts in early September. The RSI at 61 remains in positive territory without signaling excessive overbought conditions, which leaves the bullish dynamic of the week — the security gains nearly 12.3% over seven days — without immediate signals of exhaustion.
An extreme valuation driven by the annual surge of more than 344%
The performance of Soitec over one year reaches +344.5%, an exceptional progression that reflects the succession of catalysts since autumn 2025. The Isère-based semiconductor substrate manufacturer notably benefited from the raising of its growth forecasts for the second quarter of fiscal year 2026-2027, driven by the acceleration of its Photonics-SOI division. Over one month, the security still displays +15.25%, a sign that the bullish movement remains broad.
This trajectory has propelled the valuation to extreme levels: according to the consensus of surveyed analysts, the security trades at approximately 200 times the earnings of the current fiscal year, a multiple that falls to 42.4 times for the following fiscal year, reflecting the magnitude of the expected catch-up in results. The VIX ticks slightly higher to 17.22 this Friday, in a macroeconomic context marked by the increase in the ECB's key rate to 2.50% decided yesterday, which weighs on the elevated valuations of technology stocks. The next resistance level to watch remains set at 146.35 €, a threshold that has already triggered significant profit-taking during the latest sessions.
