Named conviction long on the AI-datacenter optics and power supply chain
Posts high-conviction, tickered long theses and position upd
Grade = how their written analysis reads (A best). Trader score = how their last-20 timestamped calls performed vs SPY. · Analyst brief as of 2026-06-22.
Across their last 20 scored bets: 55% hit rate, +1.17% mean alpha, trader score +1.46. Their last-14d mentions, direction-adjusted, have moved -5.2% since posting (mean over 10 mentions with price data).
jaysyoon is concentrated in AI neocloud exposure, repeatedly preferring NBIS over CRWV while still disclosing a small CRWV long. The distinctive read is that AI compute economics, financing structure, ARR mix, and revenue per MW matter more than generic backlog, with LITE framed as an optical/CPO beneficiary. The only explicit trade action was adding BW after coal plant buildout news expanded perceived TAM.
The week is concentrated in bullish neocloud and AI infrastructure exposure, led by NBIS versus CRWV and supported by LITE optical/CPO commentary. Conviction appears consistent rather than flipping, with one explicit add in BW after coal plant buildout news. Pump-risk flags are highest where discussion is concentrated: NBIS inside neoclouds, LITE inside optical, and the single-name BW power thesis.

Grade is our human read-worthiness rating; trader score is a rolling 20-bet hit-rate/alpha composite — different things, often disagreeing. “Since then” is direction-unaware in the table; the summary line above adjusts for which way they leaned.
