I bought at around 25 P/E, so I'm not worried about downside right now. I have some worries that the high-end EUV machines are difficult to operate and that manufacturing techniques can be optimized for the old EUV machines. I'll try to exit at the top and switch back to Berkshire, that's the rational thing to do, but the market is not rational right now. Or is it, Berkshire has bought Google instead of their own shares. ASML is a bet on the AI bubble future at this point with downside protection.
