Serenity, a prominent figure in AI investing, has gained attention for his unique approach to stock selection, focusing on supply chain bottlenecks rather than leading AI companies. Known for his presence on Reddit's Wall Street Bets and now on X, Serenity has amassed 473,000 followers by identifying critical suppliers in the AI supply chain. His self-reported year-to-date return is +122%, with a peak of +501%. Serenity's investment logic centers on the 'bottleneck theory,' targeting companies that are indispensable to AI infrastructure, such as AXT Inc. for indium phosphide substrates and Sivers Semiconductors for laser sources. His strategy involves investing in lesser-known, vertically integrated suppliers that are crucial to AI optical communication and silicon photonics. Serenity's portfolio spans optical communications, storage, AI cloud computing, and energy sectors, with interests in ETH and Coinbase in the cryptocurrency space.
