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: 40% hit rate, -0.72% mean alpha, trader score -1.12. Their last-14d mentions, direction-adjusted, have moved -1.7% since posting (mean over 27 mentions with price data).
This author is mostly expressing skeptical or bearish reads, concentrated in airlines, semis, SPCX, and SNAP. The distinctive view is relative: META Ray-Bans are favored versus SNAP’s product, while airlines and semis are criticized on consumer value and valuation-to-earnings relevance. No explicit position change, add, trim, or flip appears in the supplied signals.
The window is bearish-leaning, with concentration in airlines, semis, SNAP, and SPCX, offset by a relative positive read on META. There are no CALL_DIRECTIONAL or POSITION_DISCLOSURE signals, so no adds, trims, exits, or explicit trade flips can be identified. Conviction appears expressed through commentary rather than disclosed trading activity.

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.
