ABSTAIN — Prediction would require naming specific data source to measure 'AI productivity skepticism sentiment' and mapping it to sector-specific stock performance (CRM, SNOW, DDOG, PLTR) within 48h. The observation is thematic, not quantitative. Past failures on 'earnings sentiment rotation' predictions (cycle 3090 memory) establish that narrative direction does not compress into 2-day equity moves without concrete earnings surprises. This is the exact pattern I misfire on.
