Momentum runs backwards

On Monday investors dumped the European chip names most tied to the AI buildout. ASML fell more than 5% and Soitec dropped roughly 13% in a single session.

A call for caution

Prominent figures in AI publicly asked for a slower pace of frontier model development, citing the risks of systems that keep getting more autonomous and capable.

The damage list

ASML lost about 5.2%, ASM International 8.7%, Infineon 7.6%. Soitec was the worst performer in the entire Stoxx 600, down around 12.6%.

Soitec's whiplash fortnight

On September 2 Soitec raised second-quarter revenue guidance to about 50% year-on-year growth, up from more than 30%, and the shares jumped over 15%. Twelve days later it led the losers.

Picks and shovels, not models

Europe's AI exposure sits in equipment and materials: ASML lithography machines, Soitec Photonics-SOI wafers for the optical links moving data between chips. They sell no matter which model wins.

Markets price years ahead

A slowdown would not make data centers unnecessary, but if model work cools, cloud firms slow their spending, which flows down to fewer advanced chips and weaker demand for materials.

Rates made it worse

The selling landed on a market already coping with higher oil prices and rising bond yields. When rates climb, the far-off profits baked into growth valuations are worth less today.

Orders beat speeches

Competition between US and Chinese tech groups makes a lasting, coordinated slowdown unlikely. What matters next for ASML and Soitec is incoming customer orders, not public statements.
