Serenity, the stock-picker who back-maps the AI buildout to find the small upstream suppliers the giants quietly depend on, spent Thursday connecting a leaked corporate memo to two of his core positions and flagging a notable insider signal in his top holding.

Meta memo lights up the memory and optics theses. The day's catalyst was a published internal memo from Meta Platforms (META), the social-media and hyperscaler that Serenity holds as a profitable mega-cap whose heavy AI capex, he argues, actually funds real returns. He read the memo as confirmation of AI infrastructure ramping hard: long-term agreements (LTAs) signed with Samsung and Sandisk (SNDK) for memory and with Sumitomo Electric for fiber optics, plans to deploy 7GW of compute this year and roughly double it, capex he pegged as high as $145B, and a new chip roughly every six months through 2027. For Serenity, the multi-year memory LTAs are direct evidence of his NAND supercycle thesis — the idea that AI-driven demand for NAND flash storage vastly outstrips supply, letting producers lock in customers with prepayments. Sandisk, a NAND maker he treats as the template "supercycle" long, is a core holding, and multi-year offtake from a hyperscaler is exactly the pricing-power signal he watches for.

A CEO buys the dip at Sivers. The bigger emotional beat of the day involved Sivers Semiconductors — his single largest and highest-conviction position, the tiny Swedish maker of indium-phosphide (InP) continuous-wave lasers he views as the overlooked light-source chokepoint for co-packaged optics (CPO), where the optical engine sits beside the switch or GPU die. Sivers trades on two lines he references, the local listing (SIVE) and the US quote (SIVEF). Serenity reported three insider purchases today, most notably the CEO buying roughly 1,000,000 SEK of stock on the open market. That came after a sharp drop he attributed to two CPO-delay reports he called misleading, the Meta compute headlines, and a separate director's share sale. His read: insiders sell for many reasons, but an open-market CEO purchase is the clearest confidence signal, and it fits alongside the partnership validation he keeps citing — GlobalFoundries (GFS), a US silicon-photonics foundry whose ecosystem slides he uses to confirm Sivers' laser inclusion, and Jabil (JBL), the contract manufacturer that chose Sivers lasers for its 1.6-terabit pluggable transceivers — plus a planned Nasdaq listing.

A robotics aside. Serenity closed with a note on humanoid robots, framing Tesla (TSLA) as the mass-production anchor of his robotics supply-chain framework rather than a holding. He flagged that China ships most of the world's humanoids and argued an American inflection point may be arriving. Notably, he disclosed being long Agility Robotics via CCXI, tying the bet to commercialization with Amazon and others.
