Today was less about trades and more about reflection. Serenity, the stock-picker known for back-mapping the AI supply chain to find obscure upstream "chokepoints" — critical suppliers with few substitutes — marked crossing 900,000 followers with a long, unusually personal note about how much harder the platform has become to navigate at scale.

The post named no new positions, but it touched several of his recurring theses in passing. He pushed back, again, on outlets that dismiss ideas like Raspberry Pi (RPI) — the cheap single-board computer maker he frames as edge-AI hardware rather than a meme — and Sivers (SIVE), the tiny Swedish maker of indium-phosphide lasers he treats as the light-source chokepoint for co-packaged optics (CPO, where the optical engine sits next to the switch or GPU die). His frustration: critics label these "meme stocks" without engaging the underlying mapping work, including the role of contract manufacturer Jabil (JBL) and foundry GlobalFoundries (GFS) in scaling 1.6T pluggable optics — both of which he cites as validation nodes for the Sivers thesis rather than holdings.

He singled out one bright spot in the coverage: Belgian outlets reporting on x-fab (XFAB), the small German foundry he holds as a deep-value bet on European silicon photonics and US silicon-carbide power chips.

Serenity also reflected on how his audience has changed. He recalled an earlier period of trading ideas like AXT (AXTI) — his indium-phosphide substrate chokepoint call, the upstream material feeding optical interconnects — alongside Nebius (NBIS), his favored "Neocloud" AI infrastructure name, and Astera Labs (ALAB), a connectivity play he has since cooled on as the industry shifts toward optics. Back then, he said, the conversation was among knowledgeable traders; now a flood of newer followers misses nuances like share dilution or rate moves, and reacts to ordinary volatility — he cited panic over a 2% intraday dip in a recent idea (ticker CBRS, a roughly $44B company he floated last Friday) that he says later closed up more than 20%.

The operational upshot: he now runs posts through a compliance review and times new ideas for after the close to avoid spooking the crowd. He reiterated that he keeps his core ideas free and built his subscriber chat almost by accident, setting the price low deliberately.

For Reddit (RDDT) holders — his largest social-media conviction long, which he calls a misunderstood high-margin compounder — there was no fresh thesis today, only the irony of a man complaining at length about the very platforms he invests around. Nothing changed in the portfolio; the tone did.
