Memory selloff creates opportunity, with SNDK the disclosed long

The author discloses an existing SNDK long and argues that memory stocks prematurely price a supply shock before competing capacity, yields and qualification are proven. Their broader bullish calls include AI-memory repricing, ASML supply constraints and AVGO fundamentals despite management communication concerns. A conditional SNDK entry near $1,420 on October 13 is followed by confirmation of an existing long on October 14; the payload does not establish an additional purchase.

Direction this week

Conviction centers on memory repricing and a premature supply-shock discount, with SNDK providing the only directional trade signal and disclosed position. The conditional entry is followed by a held-position update, with no explicit add, trim or exit; the two-signal AVGO and watchlist themes provide limited evidence for assessing promotional concentration.

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.
