Anon semiconductor supply-chain obsessive turning deep node/packaging knowledge into high-conviction trades
Posts original, technically deep semiconductor and AI-infras
Grade = how their written analysis reads (A best). Trader score = how their last-20 timestamped calls performed vs SPY. · Analyst brief as of 2026-07-03.
Across their last 20 scored bets: 75% hit rate, +1.22% mean alpha, trader score +3.13. Their last-14d mentions, direction-adjusted, have moved +1.6% since posting (mean over 37 mentions with price data).
The author is mainly attacking Nvidia's Rubin/networking narrative while intermittently positioning Intel as a potential alternative or policy-backed beneficiary. Their distinctive read is that commodity memory and photonics hype are over-owned, while differentiated low-voltage inference and hyperscaler custom silicon deserve more credit. Late in the window, Intel commentary turned negative, so the INTC leg looks less stable than the sustained NVDA bearishness.
The author stayed consistently bearish on Nvidia, repeatedly framing Rubin, networking, and markup exposure as shortable hype. Intel started as the implied long or policy-backed alternative, then flipped negative on July 2 with dismissive comments, while new late-week focus shifted toward hyperscaler custom silicon and low-voltage inference. Concentration is highest in the Nvidia short thesis, with memory and photonics used as supporting bearish infrastructure narratives.

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.
