Rotation Read

Sharp reversal from Tuesday’s defensive rotation. On October 20, Health Care (+2.37%), Real Estate (+1.70%), and Utilities (+1.26%) led while Technology (-0.28%) lagged. Today the mirror image: Technology (XLK +1.64%) and Industrials (XLI +0.90%) lead, while Tuesday’s winners — Health Care (-0.94%), Staples (-0.58%), Real Estate (-0.21%) — lag.

The driver is AI-capex optimism: SpaceX reported Q3 revenue up 161% YoY to ~$14.6B (shares +8.15% at 9:40 AM) and disclosed SpaceX/Tesla merger committees; Super Micro raised its revenue guide to $18.5–19.5B; Jensen Huang made bullish remarks in Berlin. Utilities (+0.55%) are trading as AI infrastructure (Constellation +3.38%, Vistra +3.40%, Oklo +1.93%) after Musk flagged power and cooling as the binding constraint on AI compute.

Caution flags: Meta (-1.59%) and Alphabet (-1.11%) lag ahead of Meta and Tesla earnings after today’s close; the 10-year yield sits at ~5.13% with a $13B 20-year auction this afternoon; VIX futures remain in contango. Risk-on at midday, but fragile.
