Morgan Stanley's upgrade and price target hike boost Soitec (SOI)
Morgan Stanley significantly raised its price target for Soitec, propelling shares of the French semiconductor materials manufacturer. The stock is up 5.0% today, 21 May 2026, trading at €165.90, following a previous close of €158.00.
The surge follows Morgan Stanley's upgrade on 19 May 2026, when it increased its price target on Soitec to €200 from €70, while maintaining an "overweight" recommendation. The investment bank contends that the market undervalues Soitec's growth prospects in artificial intelligence, particularly through its substrates for silicon photonics and the anticipated rise of co-integrated optical architectures.
Soitec shares continue an upward trajectory, having advanced 10.4% yesterday and 2.1% on 19 May 2026, the day the company reported annual results for FY2025-2026 that surpassed market expectations. This movement also aligns with a broader rebound across European technology stocks and the semiconductor sector.
Why Morgan Stanley Sees Soitec's AI Potential as Undervalued
Soitec, a French company, specialises in advanced semiconductor materials. They design and produce ultra-thin, complex silicon wafers, known as substrates, which form the foundational layer for high-performance electronic chips. These specialised materials are vital for demanding applications such as artificial intelligence, 5G technology, and the automotive sector, where they significantly enhance component speed and energy efficiency. Their clientele consists of major semiconductor manufacturers who integrate these substrates into their own chip fabrication processes.
The primary catalyst for Soitec's share price movement today is a significant upgrade from Morgan Stanley. On 19 May 2026, the investment bank dramatically increased its price target for Soitec from €70 to €200 per share, while reiterating its "overweight" recommendation. This substantial revision stems from Morgan Stanley's conviction that the market has underestimated Soitec's potential in artificial intelligence, particularly through its substrates for silicon photonics and the anticipated rise of co-integrated optical architectures, following the company's better-than-expected annual results and a 10.4% share price rise the previous day.
This notable re-evaluation by a major market player has propelled Soitec's shares, which are currently trading up 5.0% at €165.90. The stock had closed the previous session at €158.00.
Imagine a highly respected architectural critic who, after a thorough review of a new building project, drastically raises their estimate of its final value. This new, much more optimistic assessment comes because they have identified major structural innovations and future-proof designs that had previously gone unnoticed. Their revised valuation signals to the market that the project's true potential is far greater than initially believed, drawing in new interest and investment.
