Soitec Shares Fall 2.77% at Close in a Deteriorated Technical Context
Soitec's stock closed Monday, December 8, 2025 session down by 2.77%, at 26.37 euros, with moderate trading volumes representing 0.44% of the exchanged capital. The French semiconductor materials specialist is now trading nearly 70% below its level at the beginning of the year, in a pressured sector environment and a particularly deteriorated technical context.
Session Overview
The stock of the Isère-based group dropped 2.77% during the December 8 session to close at 26.37 euros, after finishing the previous day at 27.12 euros. This decline is part of a broader downward trend, with a decrease of 0.68% over the last week and a drop of 20.14% over the past three months. On December 4, J.P. Morgan Chase lowered its stake below the 5% threshold in Soitec to hold 4.21% of the capital, signaling a disengagement from a major institutional investor. Over the past year, the stock has shown a catastrophic performance of -69.51%, while the CAC 40 has gained 9.18% over the same period. Trading remained relatively moderate with 0.44% of the capital traded during the day, indicating a certain caution among investors.
Technical Analysis
Technical analysis reveals a particularly concerning picture for the stock. The RSI is at 28, a level clearly in the oversold zone indicating intense selling pressure and suggesting a phase of exhaustion for the downward movement. The price is significantly below its moving averages: 38.28 euros for the MM50 and 43.52 euros for the MM200, underlining a resolutely bearish underlying trend. The MACD shows a line at -3.28 against a signal line at -3.32, with a slightly positive histogram at 0.04, which could be a technical signal of stabilization in the very short term. The stock is currently navigating between a support at 23.30 euros and a now distant resistance at 42.69 euros, with a one-month volatility reaching 39.82, reflecting the instability of the issue.
Financial Performance
Soitec published on November 19 its semi-annual results for the fiscal year 2026, with second-quarter revenue of 139 million euros, up 47% from the previous quarter but down 36% year-on-year. The group is suffering the consequences of a challenging environment in the semiconductor sector, particularly in the RF-SOI segment for smartphones. The group achieved a revenue of 0.9 billion euros during its 2024-2025 fiscal year. The persistent weakness of the stock can be explained by a combination of structural factors: destocking by customers, limited visibility on demand recovery, and declining confidence from institutional investors, as evidenced by recent threshold crossings downwards.
