A quiet day for the stock-picker known as Serenity, whose lone observation centered less on a new position than on a market pattern he found hard to ignore: Taiwan's equities are wildly outrunning their US and European counterparts.

Serenity, who builds his portfolio by back-mapping the AI supply chain, pointed to the striking divergence between Taiwanese stocks and the rest of the developed world. That geography sits at the heart of his framework. His anchor holding, Taiwan Semiconductor Manufacturing (TSM) — the contract chip fabricator that manufactures the advanced processors nearly every AI company depends on — is the "money-printer" he holds as a safe center of gravity while he chases smaller upstream names. He treats TSM as the cleanest proxy for the entire AI trade and for hyperscaler spending.

That spending, in his telling, is ultimately telegraphed by NVIDIA (NVDA), the dominant AI-chip designer whose roadmap he uses as a demand signal. Serenity notably does not own NVDA, viewing it as a crowded mega-cap; instead he front-runs its suppliers, hunting the obscure upstream "chokepoints" — critical parts makers with few substitutes — that NVDA's growth quietly makes scarce.

Today's example was one such supplier. He highlighted a Taiwanese optical-components maker that feeds both NVDA's and TSM's supply chains, describing a share price that has whipsawed dramatically — roughly quadrupling, halving, and then doubling again — before rebounding unusually fast from a July low. The company operates in the optical interconnect space that is central to Serenity's dominant investment theme: the light sources and photonics parts that carry data between chips inside AI data centers. As bandwidth demands climb, this optical plumbing becomes a bottleneck, which is exactly the kind of upstream scarcity he tries to own ahead of the crowd.

What seemed to puzzle him was the disconnect between that resilience and the broader macro backdrop. He wondered aloud whether earnings at certain Taiwanese suppliers — he name-checked memory-chip firm Etron as an example — are simply strong enough that these companies are shrugging off macroeconomic worries entirely. It is a question rather than a conclusion, but it reinforces a recurring thread in his thinking: that the AI buildout is powerful enough to decouple its key suppliers from the usual market gravity, and that Taiwan is where much of that action is concentrated.

For readers following his book, there was no fresh trade to report today — no new buys, sells, or sizing changes disclosed. Instead, the note reads as a temperature check on his home turf. The takeaway is thematic: Taiwan's outperformance validates, at least directionally, his long-standing bet that the indispensable upstream layer of the AI economy sits disproportionately on that island, and that stocks like TSM and the smaller optical suppliers around it are where the demand from NVIDIA's roadmap ultimately lands.
