Alphabet Inc. (GOOGL) shares fell 12.6% on 29 October 2026, the session after it filed its results with the SEC. Below are the closes, how unusual the move was, and what the company filed.
The move
Alphabet closed at $283.82 on 29 October 2026, down 12.6% from $324.89 on 28 October, its largest one-day fall since at least 1 November 2024, the start of the daily closes we hold. About 139.7 million shares traded on 29 October, 5.5 times the average of the 20 sessions before. In the 20 sessions to 28 October its daily changes had a standard deviation of 1.4% (20-day realized volatility of 22.1% a year), so the move on 29 October was about 9.1 times a normal day.
What the company filed
Filed with the SEC from 25 October to 29 October, as listed on EDGAR:
- 28 October: 8-K (Item 2.02, results of operations; Item 9.01, financial statements and exhibits).
- 29 October: 10-Q, the quarterly report.
The latest quarter
In the quarter to 30 September 2026, from the 10-Q filed on 29 October: revenue was $127.6B, up 24.7% on a year earlier; the operating margin was 31.8% against 30.5%; diluted earnings per share were $2.12 against $2.87; capital spending was $51.4B, up 114.4%; free cash flow (operating cash flow minus capital spending, our calculation) was minus $9.1B against $24.5B. Each figure is against the same quarter a year earlier.
The base rate
In the daily closes we hold for the 50 largest US companies, there were 33 earlier one-day falls of 10% or more that were also at least 3 times a normal day, at 22 companies, the latest on 8 September 2026. Five sessions later the median stock was up 0.5% from its close on the day of the move; 20 sessions later it was up 5.0%, and 25 of the 33 closed above that day’s close. Alphabet had not moved like this in the period. This counts what happened before, across different companies and markets; it is not a forecast.
What this note does not say
The filings do not give a reason for the share price move, and neither do we: this note puts the closes and the filings side by side. Every quarter Alphabet has filed, each linked to its filing, is on the GOOGL page at /s/googl.
