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: 65% hit rate, +2.94% mean alpha, trader score +1.67. Their last-14d mentions, direction-adjusted, have moved -3.9% since posting (mean over 104 mentions with price data).
Biz_zatukora is concentrated in AI semis and memory, with repeated bullish framing on MU, SNDK, DRAM, NVDA, SMH and the broader SOX complex. Their distinctive read is that memory and AI hardware strength is earnings- and supply-driven rather than just bubble behavior, while weak small-cap dream stocks should be avoided. Late in the window they acknowledged bearish FOMC/MSQ expectations were wrong and shifted emphasis back to staying engaged with AI and semiconductors.
Conviction is concentrated in AI semis, memory and NBIS, with repeated bullish support for MU, SNDK, DRAM, NVDA, SMH and SOX while pushing back on semiconductor shorts. There is no clear ticker-level flip, but he admits bearish FOMC/MSQ expectations were wrong and argues cash waiting reflects bias. Bearishness is concentrated in weak small-cap dream narratives such as SKLZ and CRWV, while NBIS has pump-risk because it is a focused late-week preference over IREN.

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.
