Their picks, scored

Across their last 20 scored bets: 45% hit rate, +0.63% mean alpha, trader score +0.78. Their last-14d mentions, direction-adjusted, have moved -4.6% since posting (mean over 176 mentions with price data).

AI memory bottlenecks and premium SaaS dominate window

SergeyCYW is mainly pushing AI memory/storage bottleneck exposure and premium SaaS growers, with a disclosed large SNOW position increased before earnings. His distinctive read is that AI infrastructure upside extends beyond GPUs into HBM, NAND, HDDs, controllers, storage systems, and semi equipment, while SaaS dispersion favors PLTR/DDOG/SNOW-style leaders over weaker seat-based names. No clear flip appears; the week shows repeated reinforcement of memory and SaaS screens rather than a discrete reversal.

Direction this week

The author is consistently bullish on AI memory bottlenecks and repeatedly returns to MU, SK Hynix, SNDK, Samsung, Kioxia, storage, controllers, and semi equipment as beneficiaries. SaaS coverage is more selective: bullish on premium growth and efficiency leaders such as PLTR, DDOG, and SNOW, while bearish on weaker seat-based SaaS names like CRM, NOW, and ADBE. The only explicit position action is adding to SNOW before earnings; there is no clear evidence of a flip.

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.
