Korean retail conviction bull running a power-scarcity AI-infrastructure thesis, IREN above all
Builds and continuously defends long-term theses on AI-infra
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: 45% hit rate, +0.18% mean alpha, trader score +0.13. Their last-14d mentions, direction-adjusted, have moved -5.5% since posting (mean over 186 mentions with price data).
Author is heavily concentrated in IREN as the core AI power/data-center trade, with disclosed exposure also in RKLB, MRVL and SK Hynix-related memory. Distinctive read is that scarce grid-connected power, Nvidia DSX ecosystem linkage, neocloud demand and memory bottlenecks create a multi-year AI infrastructure basket. Late week, the author added MRVL/SK Hynix exposure, kept emphasizing IREN catalysts, and surfaced a very bullish NBIS 2030 upside call while still flagging neocloud financing risk.
Conviction stayed concentrated in IREN throughout the window, with repeated long-term targets, position-size disclosures, Spain power expansion, Nvidia DSX framing and year-end/2027 catalyst references. Exposure broadened late week into MRVL/SK Hynix, MU/DRAM and optics, while NBIS conviction intensified with a 2030 upside estimate and Nasdaq-100 inclusion news. The main caution is not a flip: he repeatedly flags financing, ATM issuance and execution risk across neoclouds, and IREN is a clear pump-risk concentration.

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.
