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: 70% hit rate, +0.22% mean alpha, trader score +0.49. Their last-14d mentions, direction-adjusted, have moved +0.9% since posting (mean over 22 mentions with price data).
tphuang is primarily calling continued Chinese industrial and AI-stack self-sufficiency, with recurring constructive reads on BYD execution and domestic model progress. The distinctive read is that GLM/Zai, Ascend optimization, domestic chips, materials, and supply-chain localization weaken U.S. AI/data-center and Nvidia-led assumptions. Late-window attention shifts toward upstream bottlenecks in tungsten/WF6, indium/InP, LFP, fiber optics, and memory materials rather than single-stock trades.
Conviction is concentrated in China industrial self-sufficiency: BYD-led EV execution, Chinese model progress, domestic AI chips, and upstream materials control. The directional tilt is bearish on NVDA and parts of U.S. AI capex while constructive on BYD and Chinese ecommerce challengers. Late-window signals intensify around tungsten/WF6, indium/InP, LFP, fiber optics, and memory bottlenecks, suggesting the author is moving upstream in the supply chain narrative.

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.
