Their picks, scored

Across their last 20 scored bets: 70% hit rate, +1.39% mean alpha, trader score +2.38. Their last-14d mentions, direction-adjusted, have moved -7.8% since posting (mean over 41 mentions with price data).

Buying the selloff while questioning crowded trades and credit

Polvah recommends small periodic purchases during the selloff and explicitly added GOOGL, VST, CRDO, CRWV and RKLB. The distinctive stance combines bearish inflation commentary with selective buying, including a CRWV addition after highlighting its customer concentration and credit risks. ASTS coverage combines a cautiously bullish operational thesis with later criticism of its portfolio impact; QQQ remains a conditional purchase intention.

Disclosed booknames the author says they hold — positions, not commentary

Direction this week

Bullish activity is spread across a six-name periodic-buying recommendation and five disclosed position additions, while MRNA draws an explicit bearish valuation critique. CRWV was added on October 15 after its concentration and credit risks were discussed on October 14; no trim or exit disclosures appear. ASTS accounts for half of the space theme's signals, with constructive operational commentary alongside negative performance observations.

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.
