Meta: three straight post-earnings selloffs, first in 20 reports

The claim. Meta is beating on revenue and getting sold on spending. Three reports in a row the stock has fallen on the next session, which has not happened in the 20 reports since 2022. The question each time was the same: how much more capital before the AI investment pays back, and who funds it.

Caption: the move in the session after each earnings release. The three red bars are April, July and October 2026.

Why

1. The streak is new. Next-session moves: -8.6% (Apr 30), -8.0% (Jul 30), -7.0% today, -21.7% compounded. In the 17 reports before them, the longest run of declines was two. Today's close of $648.85 is 16.6% below the Sep 24 high. Source: Alpaca daily closes via BirdEye, as of the Oct 22 close.
2. The sales were fine. Q3 revenue $64.6B, +26% year on year. Ad impressions +10%, price per ad +14%. Q4 revenue guidance $73-76B. Source: Meta Q3 2026 release (8-K), Oct 21.
3. The costs were not. Costs and expenses $51.6B, +68%. Operating margin 20% against 40% a year ago. Capex $34.9B in the quarter. Free cash flow -$2.1B against +$10.6B a year ago, and no buybacks against $3.3B. The 2026 capex range moved to $135-145B and total expenses to $175-179B, with "aggressive" investment to continue into 2027.
4. Two one-offs made it look worse. A $9.89B charge for the settlement with 52 attorneys general over teen mental health, which allows payments of up to about $18.6B. Without it, EPS was $7.40 against $3.83 reported. And a new non-voting Class C share, paid as a one-for-one dividend in January 2027, which works like a 2-for-1 split but gives Meta a way to issue stock without diluting control.
5. Meta led a broad AI selloff. Today: META -7.0%, AMZN -4.6%, NVDA -4.4%, GOOGL -3.2%, MSFT -2.2%, QQQ -2.9%, SPY -1.2%.

What we expect

• Base case (to the Q4 report, late January): the stock tracks the 2027 capex number more than revenue. If January's guidance puts 2027 capex growth below 2026's and free cash flow back above zero, the streak ends with a positive reaction. Signal: a guidance range whose top end is below $175B.
• Alternative: 2027 capex is guided up again and Class C shares are issued to fund it. Then the pattern continues and the stock retests the April post-earnings low. Signal: any Class C issuance announced before the Q4 report.

What would change our mind

• Free cash flow turning positive in Q4 without a capex cut. That would mean revenue is outrunning the spending, the opposite of what the last three reactions priced.
• Peers diverging. If Alphabet, Microsoft and Amazon report similar capex increases next week and are not sold, the problem is Meta's funding mix, not AI spending in general.
