$ASML is falling on a report from China. Beijing can reportedly manufacture DUV lithography machines on its own—a lower-generation technology on which ASML long held a virtual monopoly.

China is systematically striving to break free from dependence on the Western tech chain and replace imported equipment with domestic production. The market reacts instantly to any such move.

The impact is visible immediately—ASML shares are weakening significantly, dragging down the entire chip sector in Europe and globally. DUV is not cutting-edge technology; that remains EUV, where ASML's monopoly still holds firm. Even so, it is a tangible blow to the business.

Be prepared for heightened volatility across the sector until the real scale of Chinese production becomes clear.
