Alphabet falls after lawsuits allege fraud over Gemini 3.5 Pro disclosures

What happened

Alphabet (GOOG) fell 3.1% on October 22, 2026, after class action lawsuits accused the company of securities fraud tied to disclosures about the development progress of its Gemini 3.5 Pro model. The stock closed at $320.76.

Trading volume ran 1.4 times its 20-day average as law firms and plaintiff notices said the suits target investors who bought shares between May 19, 2026, and July 16, 2026, and noted a December 1, 2026, lead plaintiff deadline. Those filings and press notices were cited as the most prominent immediate trigger for the selloff.

Other items that day were secondary to the legal news. Alphabet said it will launch Google Cloud's A5X Vera Rubin compute instances in November and disclosed large-scale GPU arrangements with SpaceX that it says provide access to roughly 110,000 GPUs to speed model training. Finnish authorities ordered work stopped at two datacenter sites after finding the company had illegally felled 250,000 trees, provoking public anger in Finland.

How big was the move

The decline was 1.7 times a typical daily move for the stock and was 3.8 percentage points worse than the Communication Services sector median, which rose 0.7% that day. The S&P 500 fell 1.2%, so the stock's drop substantially exceeded both the market and its sector. The stock's market value is $4.12 trillion and its market sensitivity is captured by a beta of 1.20, indicating it tends to move more than the market.

In the past five years the stock had 59 sessions with a decline of at least 3.1%; twenty trading days later the median result was a gain of 0.9% and 30 of 59 were higher, suggesting mixed short-term follow-through after comparable selloffs.

The technical picture

The stock traded 5.9% below its 20-day moving average, 5.7% below its 50-day moving average and 5.5% below its 200-day moving average, while the 50-day average is above the 200-day average, a sign of an established uptrend. The stock is 20.7% below the 52-week high and the Relative Strength Index (14 days) stands at 33, which is within a neutral range.

Over one month the stock fell 4.2%, over three months it rose 0.5%, and over one year it rose 27.6%, which is 13.8 percentage points ahead of the S&P 500. Volatility was 28% annualized over 60 days, which is lower than 62% of its own readings over five years, indicating recent price swings were modest relative to the stock's history.

Fundamentals and valuation

For the four quarters through June 30, 2026, Alphabet reported revenue of $445.87 billion, which grew 20.1% from a year earlier, and diluted earnings per share of $19.91, which rose 112.0% from a year earlier. Gross margin was 60.9% versus 58.9% a year earlier and operating margin was 33.1% versus 32.7% a year earlier. Free-cash-flow margin stood at 11.9% and return on invested capital was 15.2%.

The balance sheet shows net debt of 0.2 times EBITDA and share count over one year increased by 0.9%. Valuation measures show the stock trades at 16.1 times trailing earnings and 15.6 times expected earnings, with a free-cash-flow yield of 1.3%. Its price to trailing earnings is lower than 95% of its own readings over the past five years; the five-year median is 24.3 times earnings, suggesting investors are paying materially less for current profit than in most of the past five years even as margins expand.

PromtFinance scores rank the company Strong on Growth at 83 and Strong on Quality at 81, with Revisions at 98, Exceptional.

Earnings and analyst expectations

Alphabet's next report is scheduled for October 28, 2026. The last report, on July 22, 2026, delivered earnings per share of $9.11 against $2.87 expected, 217.4% above estimates, and was part of a 14-quarter streak of beating estimates. The average surprise over the last four reports was 85.0% above estimates, and the typical two-day reaction after recent reports was the stock rose 0.7%.

Analysts place a consensus price target of $435.29, which is 35.7% above the closing price, based on 79 analysts with 87% rating the stock Buy or Strong Buy and a consensus rating of Buy.
