@ALEXEIMARTOV ALEXEIMARTOV
PM running a long/short book on the AI-memory cycle with primary-data rigor
Discloses and reasons through a real long/short equity portf
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: 50% hit rate, +1.42% mean alpha, trader score +2.04. Their last-14d mentions, direction-adjusted, have moved +0.7% since posting (mean over 25 mentions with price data).
ALEXEIMARTOV’s window is concentrated in an AI and memory-cycle fund-letter basket, with disclosed positions across SNDK, INTC, HY9H.DE, DAVE, 9984, and CELC. Distinctive incremental work is a software-capability roll-up thesis where AI model firms may pursue BOX and GTLB, while AAPL commentary is two-sided between management and memory-cycle concern versus M-series performance praise. No clear position flip is visible from the supplied signals, though AAPL sentiment is mixed late in the window.
The supplied window shows new disclosed fund-letter positioning around AI and memory-cycle exposure, then a separate AI software roll-up thesis centered on BOX and GTLB. AAPL is the only clear late-week two-sided ticker, with one bearish management and memory-cycle take followed by a positive M-series performance comment. There are no CALL_DIRECTIONAL signals or explicit add, trim, exit, or flip disclosures in the input.

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.
