Soitec stock among the sharpest declines in the SBF 120 despite +26.5% in one month

In an SBF 120 that remained nearly stable on Monday, Soitec stands out as an exception in the opposite direction, posting one of the rare notable declines in the index. The pullback continues a mixed week, as the stock had taken a correction last Thursday following a spectacular September.


Soitec stock among the sharpest declines in the SBF 120 despite +26.5% in one month

Soitec in the lower ranks of the SBF 120, penalized after its exceptional monthly rebound

Soitec loses 1.99% to €140.20 in trading, placing itself among the sharpest declines in the SBF 120 (rank 117 out of 120 members), while the index remains virtually unchanged (+0.08%). Monday's underperformance follows the 4% decline recorded last Thursday, which had already dampened the stock's spectacular rebound. Over the past week, the change remains very contained at -0.57%, but September maintains a performance of +26.88%, and the three-month gain reaches +22.61%, reflecting the scale of the bullish movement that has driven the stock since early September.

This dynamic had been fueled by the increase to approximately 50% of the revenue growth forecast for the second quarter, announced in early September, which had propelled the stock to the top of the index on several occasions. Over one year, the increase remains impressive at +269.4%, which partly explains the profit-taking weighing on the stock at the beginning of the week.

A pullback that tests the underlying bullish dynamic, with RSI still balanced above moving averages

Despite today's decline, the technical configuration of Soitec remains structurally bullish. The price at €140.20 holds above the 20-day MA at €134.94 (difference of +3.90%) and well above the 50-day MA at €120.94 (difference of +15.93%), two levels that had served as springboards during the rebound phases of recent weeks. The RSI at 58 remains in neutral territory, far from an overbought signal, which leaves the dynamic open without indicating immediate exhaustion.

The support at €107.85 is very far from the current price, while resistance at €154.85 represents the next level to watch. Furthermore, valuation remains elevated: according to the consensus of analysts surveyed, the stock trades at approximately 41.8 times the expected earnings for the next fiscal year, a level that reflects growth expectations but leaves little room for any disappointment. The resistance at €154.85 remains the benchmark to watch for assessing the continuation of the bullish movement.
