Anonymous deep-dive semiconductor supply-chain analyst obsessed with lithography and packaging mechanics
Posts granular, mechanism-driven analysis of the semiconduct
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: 35% hit rate, -0.72% mean alpha, trader score -0.85. Their last-14d mentions, direction-adjusted, have moved -3.6% since posting (mean over 17 mentions with price data).
Author is concentrated on semiconductor manufacturing infrastructure: EUV scaling, advanced packaging, photonics capacity, lithography materials, and input constraints. The distinctive read is that prototypes and announcements matter less than production scale, outsourcing, supply-chain localization, and tool/material bottlenecks. No CALL_DIRECTIONAL or POSITION_DISCLOSURE signals appeared, so the window reads as research/news curation rather than explicit trading.
No explicit directional calls, adds, trims, exits, or position disclosures appeared in the payload. The author stayed concentrated on semiconductor process infrastructure, especially EUV production realism, U.S. packaging localization, photonics capacity, lithography materials, and supply inputs. Conviction reads research-driven and consistent rather than demonstrably intensifying, fading, or flipping.

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.
