Soitec Shares Drop 2.5% and Fall Below €116.50 Support Level

The Isère-based semiconductor substrate specialist has erased part of its rebound from the previous day. The stock is among the biggest decliners in the broad Paris index in a downward trending Parisian market. However, the downward pressure from short-selling funds continues to significantly ease.


Soitec Shares Drop 2.5% and Fall Below €116.50 Support Level

The stock falls below its €116.50 support level and remains far from its moving averages

Soitec shares fell by 2.63% to €109.30 in mid-morning trading, among the sharpest declines in the SBF 120. The stock has significantly fallen below its technical support at €116.50, which had been breached on Tuesday and then briefly regained during an 8% rebound the previous day. The price remains significantly distant from its short-term moving averages, with a 23.53% gap below the MM20 (€142.93) and a 20.15% gap below the MM50 (€136.89), indicating the severity of the correction over the past month.

The RSI at 44 remains neutral, with no oversold signal despite a 38% decline over a month. The underlying momentum remains dramatic, with the stock still up more than 100% over three months and 135.9% over a year.

According to reviewed statements, two funds now hold a combined net short position of 1.14% of the capital, compared to 3.20% a month ago. The retreat of more than two percentage points in thirty days reflects a gradual covering movement after the high plateau reached at the end of May, when the stock soared following the annual accounts. This easing of bearish positioning accompanies but does not trigger the aborted rebound from the previous day, without yet signaling a complete reversal of sentiment as shorts remain.

The sequence remains to be followed without overinterpretation, in a globally turbulent semiconductor sector. On the fundamentals side, during the annual results for the fiscal year 2026 published on May 27, 2026, the group had highlighted among its growth levers the adoption of Photonics-SOI solutions for data centers and the artificial intelligence market, contrary to an environment still penalized by the correction of RF-SOI client inventories.
