Soitec Leads SBF 120 After Breaking Through Its Support at €116.50
Soitec's stock is up 8.01% at €115.90, taking the lead of the SBF 120 as the broad index gains 0.29%. The rebound comes after a challenging month, with the stock still down nearly 35% over thirty days. The session remains technical: the price broke through its support at €116.50 intraday and is still trading below this level at the time of writing, after having broken it the previous day. The stock remains well below its MM20 (€142.93) and MM50 (€136.89), with respective gaps of nearly 19% and 15%. The RSI at 44 remains neutral, indicating a technical rebound without a real reversal signal. Nonetheless, the quarterly performance remains exceptional at +128.6%, and the price is still significantly above the MM200 at €61.74.
Reduction in Bearish Bets and a Supportive Background for Semiconductors
According to reviewed statements, two funds now cumulatively hold 1.14% of the capital sold short, down from 3.27% thirty days ago, a decline of 2.13 points. This rapid regression from a high level suggests a movement to cover short positions, without presuming a fundamental change in sentiment towards the stock. The movement needs to be monitored over time to determine if it is part of a sustained decrease or just a tactical adjustment. The session also takes place against a more settled backdrop for the sector, with STMicroelectronics up 3.74% among the strongest gains in the SBF 120. During the annual results announcement on May 27, 2026, management highlighted the demand related to AI and the adoption of Photonics-SOI solutions for data centers, while noting inventory corrections among its clients as the main drag. The next technical milestone: the reconquest of the MM50 at €136.89.
