Soitec Shares Soar 5.77%, Leading the SBF 120 Following a Deal in China
The Isère-based semiconductor substrate specialist marks a significant rebound mid-morning, after several challenging weeks. The stock takes the lead of the broad Paris index, in a market that is otherwise trending downward. An industrial partnership forged in Asia fuels this renewed interest.
Soitec Takes the Lead in the SBF 120 Following Partnership with ZenSemi
Soitec shares gain 5.77% to €120.95, leading the SBF 120 while the index itself is down 0.23%. The stock benefits from today's announcement: a strategic partnership with Chinese foundry ZenSemi focused on the development and volume production of 300 mm BCD-on-SOI substrates for power electronics. The agreement strengthens the group's position in the Chinese market, one of the growth drivers mentioned during the annual results announcement on May 27, 2026. Today's rebound is part of a broader rise in the European semiconductor sector, with STMicroelectronics also up 3.44%.
A Technical Rebound That Only Partially Offsets the Monthly Decline
Today's surge mitigates the monthly decline but does not erase it: Soitec remains down more than 37% over the month, following a series of analyst revisions and highly volatile sessions. The stock price is still below its MM20 (€142.93, a gap of -15.38%) and its MM50 (€136.89), indicating that the short-term momentum remains weak despite the bounce. However, the three-month performance is still up at +124.9%, and the price remains well above the MM200 (€61.74).
The RSI at 44 remains in the neutral zone, with no signs of exhaustion. The support level at €116.50, broken in the previous session and reclaimed this morning, becomes the immediate technical reference to watch for the continuation of the rebound.
