A New Acceleration Against Market Trends
Soitec stock is the top performer in the SBF 120 this morning, far ahead of Worldline (+4.17%) and Trigano (+2.12%). The stock has gained 30.48% over seven days and has quadrupled over three months, with a performance of 419.6%. Over one year, the stock has increased by 222.7%. The intraday peak at €167.20 surpasses the previous three-year record of €165.00. This movement amplifies the momentum observed since the end of April; just the day before, the stock had already gained 5.58% to €155.05. The session unfolds in a slow Parisian environment due to the holiday, with the SBF 120 down by 0.76% at 6,182.03 points mid-morning.
Technical Configuration in Overheated Zone
The stock price at €165.65 is nearly at the upper Bollinger band limit of €166.56, a characteristic positioning of an overbought zone. The RSI at 76 confirms this tense configuration, with the stock having already exceeded the +10% mark in session five times since April 10. The gap with the 50-day moving average, at €71.98, exceeds 130%, illustrating the magnitude of the bullish detachment compared to the medium-term trend. The next significant event is scheduled on the financial calendar: the publication of the annual results for 2026 is expected on May 27, 2026.
