$ASML(ASML.US)

EUV lithography is among the most complex manufacturing systems ever built, requiring decades of engineering, a highly specialized supply chain, and coordination that is hard to replicate.

Despite heavy long-term investment, competitors have yet to deliver a viable alternative, suggesting the advantage is structural rather than cyclical.

As long as semiconductor manufacturing continues to push technical limits, ASML’s position remains intact.

Therefore, short-term price movements matter less than whether this capability becomes meaningfully replaceable.

My focus is not on forecasting the stock, but on watching for any erosion of the underlying technological moat.
