Soitec Shares Plunge 6.71% to €141.70 After a 280% Rally
The semiconductor substrate specialist experiences the sharpest decline in the SBF 120 at mid-session. Following a rally of nearly 280% over three months, the stock faces a sudden halt as the broader index falls by 1.37%. Meanwhile, net short positions have increased on the stock.
Soitec Bottom of the SBF 120 in a Pressured Paris Market
Soitec's stock loses 6.71% to €141.70 by midday, trailing the SBF 120 (-1.37%). The stock is dragged down in the general retreat of European tech values, alongside STMicroelectronics (-4.64%) and SES (-5.19%). The CAC 40 is down 1.39% at 7,969.8 points, amidst ongoing tension on Brent crude, which has crossed $109 per barrel.
Despite today's drop, the stock still holds a spectacular lead: +144% over one year and nearly 280% over three months. This movement comes after the intraday record of €180 reached on May 11th, followed by a rebound to €157.75 on Wednesday (+9% in session). Over the week, the decline reaches 6%.
In terms of positioning, selling pressure is intensifying. According to reviewed statements, cumulative net short positions reach 4.19% of the capital, declared by five funds. The ratio has nearly doubled in a month (+2.04 points over thirty days, compared to 2.15% previously). Two Sigma Investments (1.53%), Walleye Capital (0.89%), and Numeric Investors (0.67%) are among the main short sellers.
Price Still 206% Above the MM200
Despite today's drop, the price remains at €141.70, which is 10.70% above the MM20 (€128.00) and 206.58% above the MM200 (€46.22). The gap with the long-term average illustrates the magnitude of the rally accumulated over three months. The RSI at 65 is gradually exiting the overbought zone that prevailed at the end of April when the indicator had exceeded 86. In the Bollinger Bands, the stock is in the upper part at 63%, away from the upper boundary at €182.19.
The next key event is now imminent: Soitec will publish its annual results for 2026 on May 27. This deadline comes after a period of marked volatility, with the stock alternating between record highs (€180 on May 11) and severe declines within a few sessions. The technical resistance threshold remains identified at €171.35, a level approached but not surpassed in closing during the recent peak.
