Data vs consensus, and what moved markets

  • SpaceX’s first public profit. Q3 revenue of $14.58B (+161%) and Musk’s comment that a SpaceX–Tesla merger would be “a good idea” lifted SPCX 7.8% and Tesla (TSLA) +3.4%.
  • AI hardware demand. Super Micro’s above-consensus guidance lifted Dell and Hewlett Packard Enterprise (HPE) and pushed the chip index up about 2%.
  • Telecom fear. Reuters tied AT&T’s drop to worries that SpaceX’s results and spectrum buys make it a wireless competitor.
  • Earnings breadth. Capital One (COF) rallied on a big Q3 beat; Abbott (ABT) fell about 2% after trimming its sales outlook. NYSE advancers beat decliners 1.37 to 1.

Look ahead — Thursday, Oct 22

Futures will trade off Meta and Tesla tonight, with Lam Research’s slide a test of whether the chip bid holds. Bull (30%): Meta’s beat-and-raise carries the S&P to a new record. Base (50%): a mixed, choppy day as chip equipment gives back some gains and the SPCX lockup adds supply. Bear (20%): yields push higher after the soft 20-year auction and tech fades. Wick’s pick: Base.

Wick's take: Today was the kind of AI rally that has earnings behind it, not just hope, so we would give it more credit than last week’s credit-driven bounces. Still, Lam’s reaction says chip equipment is priced for perfection, and the SPCX unlock is a real supply event. We would hold winners and not chase into Thursday’s open.
