Bristlemoon Global Fund stated the following regarding ASML Holding N.V. (NASDAQ:ASML) in its fourth quarter 2025 investor letter:

“In our September 2025 quarterly letter we explained why we had taken positions in Alphabet and ASML Holding N.V. (NASDAQ:ASML). We highlighted how ASML is a monopoly in the semiconductor industry during an AI boom. Our writeup outlined the bear case arguments and explained our reasoning for why they were misguided. Other investors began to agree with our investment thesis, sending the stock from around €600 per share to north of €900 per share in the span of a quarter. Alphabet, where investor sentiment around AI had become unduly pessimistic, has also since delivered solid performance and contributed meaningfully to the Fund’s returns.”
