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, -0.48% mean alpha, trader score -0.67. Their last-14d mentions, direction-adjusted, have moved -2.5% since posting (mean over 102 mentions with price data).
dnystedt is concentrated on AI infrastructure supply-chain beneficiaries, especially TSMC advanced packaging, ASE/Amkor outsourcing, ASML equipment scarcity, optical components, and memory/storage pricing. His distinctive read is that physical bottlenecks across CoWoS/CoPoS, photonics, glass/fabric, power, and memory are becoming the investable story behind AI demand. Late in the window he added more ASML/TeraFab and Apple-Intel items, while the stance remained broadly bullish on semiconductor capacity constraints and mixed on Apple as higher component costs hit devices.
The week is consistently centered on AI infrastructure bottlenecks, with the most repeated exposure in TSMC advanced packaging, ASE/Amkor outsourcing, ASML equipment scarcity, and Taiwan AI server economics. Newer late-window emphasis appears in ASML/TeraFab commentary, Apple-Intel headlines, and memory price inflation; there are no explicit CALL_DIRECTIONAL or POSITION_DISCLOSURE signals showing adds, trims, exits, or a clean position flip. Concentration risk sits mainly in TSMC-linked packaging and broad bottleneck beneficiaries rather than single-name disclosed trading.

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.
