Concentrated bottom-up fundamentalist obsessed with CELH, ROOT and insurtech/fintech compounders
Writes detailed, valuation-driven long theses on a small bas
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, +0.47% mean alpha, trader score +1.77. Their last-14d mentions, direction-adjusted, have moved +4.2% since posting (mean over 149 mentions with price data).
bjmtweets is most explicit on PATH, initiating and disclosing a swing long tied to short float, ARR, retention, AI acceleration, and slower insider selling. He is also constructive on MELI’s moat and CELH’s consumer momentum, while late-week tone turns more cautious on AI-linked semis and the broader portfolio because of rates and overheating risk.
The week centers on a new PATH swing long, while CELH and MELI remain constructive single-name themes. Late-week tone becomes more risk-aware: he trimmed portfolio exposure on hawkish rate projections and flagged overheating in AI-linked SNDK, TSM, and MU, though still keeps MSFT on watch for AI upside and valuation.

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.
