Their picks, scored

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).

Hard AI bottlenecks beat soft AI narratives

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.

Direction this week

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.
