Soitec Shares Tumble Nearly 13%, Becoming the SBF 120's Bottom Performer
The Isère-based semiconductor substrate specialist experiences a sharp drop during the session, trailing at the end of the broad Parisian index and erasing several weeks of stabilization attempts. The stock breaks a technical support closely watched over several sessions, in a semiconductor sector once again under pressure.
A Plunge of Nearly 13% Positions Soitec as the SBF 120's Bottom Performer
Soitec shares fell by 12.84% to €103.20, down from €118.40 the previous day. The stock is now the worst performer in the SBF 120, significantly trailing behind STMicroelectronics (-6.71%) and Mersen (-4.89%), while the broad index itself gained 0.22% during the session. This downturn wipes out the rebound that began in late June following the Chinese partnership with ZenSemi on 300 mm BCD-on-SOI substrates. The loss now extends to nearly 30% over a month, although quarterly performance remains positive at over 106%, highlighting the volatility of the stock. Over a year, the stock still shows a gain of 117%. This movement is part of a semiconductor sector that is once again experiencing turbulence in Paris, with STMicroelectronics also near the bottom of the index, indicating an unfavorable sector environment that amplifies the decline of the substrate specialist.
Breaking the Support at €116.50 Drastically Lowers the Stock Below Its Short-Term Moving Averages
The session's downturn breaks the support at €116.50, a level that had been defended several times in recent weeks, notably during the rebound on July 1st. The price at €103.20 is now significantly below the MM20 at €142.93 (a -27.8% gap) and the MM50 at €136.89 (-24.6%), indicating a clear break in short-term momentum. The RSI at 44 remains in the neutral zone, without a marked oversold configuration at this stage, while the MACD continues to trend downward (line at -9.13, below its signal line). However, the MM200 at €61.74 reminds us of the extent of the rally in recent months: the price remains 67% above this long-term benchmark, despite the correction. The next technical threshold identified in the data is now significantly lower than the current price, while resistance at €192.20 becomes more distant. The next concrete milestone for the company will be the publication of its first-quarter revenue for the fiscal year, traditionally announced in July.
