Mechanistic AI-semiconductor supply-chain analyst tracing compute demand to Asian component names
Publishes deep, frequently quantified theses on how AI compu
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, -1.60% mean alpha, trader score -1.52. Their last-14d mentions, direction-adjusted, have moved -4.0% since posting (mean over 200 mentions with price data).
paurooteri is focused on AI-driven semiconductor scarcity, especially memory, advanced packaging, MLCCs, substrates, power components, and optical interconnect materials. The distinctive read is that AI demand has structurally changed pricing power across the supply chain, making aggregate cyclical analysis misleading. Late-week emphasis shifted further toward component bottlenecks and equipment beneficiaries while staying constructive on Nvidia, TSMC, ASML, KLA, STX and selective memory exposure.
The author is consistently bullish on AI-driven semiconductor scarcity, with concentration in memory, TSMC packaging, Nvidia platform economics, and passives such as MLCCs and resistors. Conviction appears to intensify late week around component bottlenecks, with multiple posts on MLCCs, resistors, capacitors, power ICs and ASML/KLA equipment. No CALL_DIRECTIONAL trades were present, and the only explicit ticker position disclosure was STX as part of an HBM/HDD allocation.

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.
