Soitec stock retreats after a 330% rebound in one year
Leading the SBF 120 yesterday with a surge of nearly 7%, Soitec loses ground on Tuesday in a Paris market otherwise oriented upward. The pullback contrasts with monthly and annual performance that remains among the most spectacular on the Paris exchange.
A marked pullback after resistance breached yesterday, in a rising SBF 120
Soitec loses 2.49% in trading at 151 €, while the SBF 120 gains 0.34% in parallel. The stock thus ranks among the sharpest declines in the index, after reaching resistance at 154.85 € yesterday — a level that had blocked several bullish attempts in recent weeks. This threshold, now retested from below, resumes its role as immediate technical reference.
The RSI at 66 remains in bullish territory without signaling extreme overbought conditions, but the bullish momentum of recent days is experiencing its first clear pause. Over one month, the stock still displays a gain of 37.52%, and 22.37% over the week, which attests to the vigor of the movement underway since early September. Monthly volatility at 30.46% reminds that these amplitudes, in both directions, are consistent with the stock's configuration.
An annual performance of over 330% driven by Photonics-SOI dynamics, tight valuation
Behind this pullback, Soitec remains one of the strongest trajectories in the SBF 120 over one year, with a progression of 330% over the past twelve months. The driver is identified: the company had raised to approximately 50% its revenue growth forecast for its second quarter 2026-2027, driven by demand for its Photonics-SOI activity, a segment benefiting from accelerating investments in data centers and artificial intelligence. This momentum led several brokerage houses to significantly revise their targets, including JP Morgan which doubled its own in September.
The counterpart to this surge is a very tight valuation: according to the consensus of analysts surveyed, the stock trades at approximately 46 times expected earnings for the following fiscal year, a multiple that leaves little room for operational disappointment. The 500 million euro ORNANE issuance maturing in 2033 launched on September 17 constitutes a recent financial context element, with a simultaneous placement of existing shares intended to facilitate hedging coverage. The 20-day moving average at 127.21 €, on which the price maintains a spread of nearly 19%, remains the first significant support level in case the pullback continues.
