Alphabet’s worst day in twenty years, in context
Alphabet fell 12.6% on October 29, its largest one-day drop since at least 2006, the day after a quarter of 25% revenue growth and negative free cash flow.
On Thursday, October 29, Alphabet's shares closed 12.6% lower. It was the largest one-day fall in the price history we hold for the company, which goes back to October 2006.
In context
Alphabet's five largest one-day falls in that history:
- October 29, 2026: down 12.6%
- March 16, 2020: down 11.6%, as the pandemic closed economies
- September 29, 2008: down 11.6%, the day the US House first voted down the bank rescue
- July 18, 2008: down 9.8%, the day after its April to June 2008 results
- October 25, 2023: down 9.5%, the day after its July to September 2023 results
Thursday's fall was larger than any day of the 2008 financial crisis or the 2020 crash. At Alphabet's size, it was roughly half a trillion dollars of market value in one session.
Below its own high
One day is one way to measure a fall. Another is how far the shares now sit below their highest close.
Alphabet's highest close was $402.62, on May 13, 2026. By the close on October 28, the day its results came out, the shares were 19.3% below that. Thursday's fall took them past 20%, the line usually drawn for a bear market, and Friday's close of $279.90 left them 30.5% below the May high.
In the past ten years Alphabet has fallen 20% or more from a high seven times, counting this one. This one is now the third deepest, just behind the 30.9% of early 2020 and well short of the 44.3% from November 2021 to November 2022. The six before it all got back to their old high, in a median of four months from the bottom; the 2022 one took fifteen months. Past falls describe what happened then. They do not say what this one will do.
What the company reported the evening before
The results release for the July to September quarter, filed on October 28, shows a business that was still growing:
- Revenue: $127.6 billion, up 25% from $102.3 billion a year earlier
- Net income: $26.2 billion, down from $35.0 billion
- Cash from operations: $42.3 billion, down from $48.4 billion
- Capital spending: $51.4 billion, more than double the $24.0 billion of a year earlier
- Free cash flow: minus $9.1 billion, from plus $24.5 billion
It was the second quarter in a row with negative free cash flow. In April to June it was minus $5.9 billion.
Not alone
Amazon, Meta and Microsoft reported the same pattern in the same weeks: revenue up, capital spending roughly doubled, free cash flow down or below zero. Together the four spent $202 billion on capital projects in the quarter, against $97 billion a year earlier. Alphabet's share price fall was simply the largest.
