Their picks, scored

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).

AI memory positions plus software roll-up basket

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.

Direction this week

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.
