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.

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.
Le chiffre d'affaires du T1'27 ressort au-dessus de notre objectif, porté par la forte accélération des activités liées à l'IA, dont les ventes en Photonics-SOI ont doublé sur un an.
Le chiffre d'affaires du premier trimestre 2026-2027 atteint 113 M€, en hausse de 23 % sur un an à périmètre et taux de change constants, au-dessus de l'objectif d'environ 15 %. La croissance est portée par l'Edge & Cloud AI (65 M€, +46 %) grâce au doublement des ventes de Photonics-SOI pour les data centers IA, et par l'Automobile & Industrie (10 M€, +108 % sur base de comparaison faible), tandis que les Communications Mobiles reculent de 10 % à 39 M€ dans un marché des smartphones sous pression et avec la correction des stocks RF-SOI. L'usine SOI 300mm de Singapour a été qualifiée auprès de premiers clients pour la production en grande série de Photonics-SOI.
