Long-form daily AI-capex macro briefer who stress-tests the bull narrative mechanistically
Publishes dense daily and weekly market-brief narratives syn
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: 50% hit rate, +0.19% mean alpha, trader score +0.23. Their last-14d mentions, direction-adjusted, have moved -4.5% since posting (mean over 119 mentions with price data).
The author is concentrated on AI infrastructure scarcity: SpaceX/SPCX as an orbital compute narrative, memory and storage names as hard bottleneck winners, and Intel/Google TPU as a shifting AI silicon stack. Their distinctive read is that scarce chips, memory, storage, power, and policy control points matter more than generic AI services exposure. No explicit trade adds or trims were disclosed, but late-window posts shifted more attention toward memory/storage winners and away from soft AI consulting and Apple margin pressure.
Conviction is concentrated in hard AI bottlenecks: SPCX narrative premium, memory/storage scarcity, Intel foundry optionality and Google TPU pressure on Nvidia. The author is bearish on soft AI monetization names, especially ACN, ORCL and SMCI, and repeatedly flags Apple margin pressure from memory inflation. There were no explicit position adds, trims or exits in the signal set; theme intensity appears strongest late week in memory/storage after multiple MU, SNDK and STX scarcity posts.

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.
