Skeptical AI capex lens with selective compounder bias

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.

Direction this week

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.
