Bottom-up quality-compounder investor obsessed with moats, unit economics, and durability
Writes long-form, reasoned fundamental theses on capital-lig
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: 30% hit rate, -1.17% mean alpha, trader score -1.63. Their last-14d mentions, direction-adjusted, have moved +1.5% since posting (mean over 50 mentions with price data).
Author is mainly warning that AI infrastructure growth may not convert into shareholder returns once overbuild, depreciation, and GPU ROI are considered. The distinctive read is skeptical of consensus AI capex beneficiaries while still favoring clean capital allocation, long-duration compounders, and selective platform assets. No explicit trade adds, trims, exits, or position disclosures appeared in the window.
The author’s window is dominated by a bearish AI infrastructure capex framework, especially depreciation, overbuild, and GPU ROI risk across NVDA, CRWV, hyperscalers, and ORCL. Bearishness also appears in ad-platform economics, with META/GOOG ads framed as margin-consuming for merchants and ODD viewed as uninvestable due to META CAC dependence. There are no explicit adds, trims, exits, or directional trade calls, so conviction is expressed through framework repetition rather than disclosed trading activity.

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.
