Soitec stock soars nearly 7% and breaks through key resistance level
Soitec establishes itself as the most dynamic value of the SBF 120 on Monday morning, in a Paris market globally up. The share of the Isère-based semiconductor substrate manufacturer breaks through its resistance at €146.35 in trading, a level that had hindered several bullish attempts in recent weeks.
A key resistance breakthrough that propels Soitec to the top of the SBF 120
Soitec gains 6.91% to €150.75 in trading, after closing at €141 on Friday, September 18. The share has broken through its resistance at €146.35 to the upside and is holding there, a breakthrough that previous trading sessions had failed to confirm. Over the week, the gain reaches 6.8%, while performance over one month exceeds 37%.
The move occurs in an SBF 120 trending upward (+0.78% in trading), with a VIX at 14.97 reflecting a calm market climate. With regard to moving averages, the share is trading well above its 20-day MA at €124.96 (spread of over 20%) and its 50-day MA at €115.77 (spread exceeding 30%), which reflects solid underlying bullish momentum since early September. The RSI at 60 remains in a neutral to slightly bullish zone, with no overbought signal at this stage, which technically leaves room for further gains.
A rally of over 329% in one year, driven by Photonics-SOI and guidance revision
Monday's rise is part of a momentum that takes root in early September, when Soitec raised to approximately 50% its revenue growth forecast for the second quarter of 2026-2027, driven by accelerating demand in its Photonics-SOI business. This revision triggered a 14% jump on September 3, followed by a series of volatile sessions mixing corrections and rebounds. More recently, Soitec launched on September 17 an issuance of convertible bonds (ORNANE) of €500 million maturing in 2033, the proceeds of which will be used for the company's general purposes, an operation accompanied by a simultaneous placement of existing shares.
Over one year, the share displays a gain of 329.6%, one of the most remarkable performances on the French market. According to the consensus of analysts tracked, the stock is trading at approximately 218 times expected earnings for the current fiscal year, a very high valuation level that reflects growth expectations around Photonics-SOI. The next identified resistance is at €192.20.
