The logic behind Google's plunge: AI has burned through cash flow, depleted buybacks, and is still burning through search

Google faced its most severe single-day plunge on Thursday, with stock prices dropping over 11% and a market value evaporating by approximately $500 billion. A "death cross" occurred during trading—where the 50-day moving average fell below the 200-day moving average—impacting a broader range of tech stocks, leading to downward pressure on the Nasdaq.

Alphabet's latest financial report hit the market's most sensitive nerve: AI investments continue to consume cash flow, stock buybacks have dropped to zero, and the pricing power of its core search business is also beginning to feel pressure. According to Bloomberg's consensus expectations, Google Search, YouTube, subscriptions, and Google Services all fell short of expectations, with the group's operating profit at $40.6 billion, below the market expectation of $43.2 billion and also below the buyer's threshold of about $45 billion.


This was not just a failure at the financial report level; it resembled a repricing of AI trading logic. Comments from JPMorgan, Goldman Sachs, and Morgan Stanley pointed to the same conclusion: this financial report has once again put pressure on the risk appetite of the recently warming AI sector, amplifying market anxiety over the returns on capital expenditures by large tech companies. JPMorgan bluntly stated that this is "a setback for reigniting AI/tech trades." Goldman Sachs trader Thales Arruda mentioned that the market is shifting from "rewarding capital expenditure growth" to "demanding evidence of returns."

The report from Alphabet presented a starkly different picture. The company's free cash flow consumption far exceeded expectations, with buybacks dropping to zero in the first nine months of 2026, while raising funds through stock sales and bond issuances. Meanwhile, Sundar Pichai emphasized that the year-on-year growth rate of search queries reached its highest level in five years, but the growth rate of search revenue has slowed, with the lower monetization rate of AI Mode becoming the market's biggest concern.

### Query Volume Hits Five-Year High, But Search Revenue Sees Lowest Growth This Year

The most unsettling contradiction for bulls in this financial report lies in a comparison of a set of numbers.

Alphabet CEO Sundar Pichai claimed in the report that the year-on-year growth rate of Google Search queries "is the highest in the past five years." However, revenue from search and other businesses only grew by 12% to $63.35 billion, a significant drop from 16.8% in the second quarter and 19.1% in the first quarter, and clearly below the buyer's expected threshold of about 14%.


In the words of JPMorgan trader Mark Schilsky, this means "Google is answering more questions than ever, but the rewards for each question are getting smaller."

Management provided multiple explanations. Chief Business Officer Philipp Schindler cited exchange rates as "the single biggest drag on search business relative to the second quarter," while Goldman Sachs' TMT team added two vertical industry factors: the EU's cancellation of the minimum exemption policy impacting advertising spending by retailers in the Asia-Pacific region, and the normalization decline in media and entertainment advertising spending following the FIFA World Cup.

However, the market's real concern is the erosion of search monetization by AI Mode. Schindler acknowledged that AI Mode has a "lower level of monetization," while insisting that "most queries in AI Mode are incremental and will create more monetization opportunities over time." Barclays analyst Ross Sandler pointed out that management is "prioritizing user experience over monetization," with the growth rate of blue link queries lagging behind the overall query growth rate, and next year's more aggressive agent-based search process may further widen this gap. He characterized this as a "yellow warning" for investors.

Morgan Stanley noted that the gap between the growth rates of Alphabet's search and Meta's advertising has widened to a recent peak of about 13 percentage points, reinforcing market concerns about advertising share migration and AI diversion.

YouTube also failed to provide a buffer, with revenue growth of 9.2%, falling below the 10% observation line mentioned by JPMorgan's Mark Schilsky.

Looking ahead to the fourth quarter, CFO Anat Ashkenazi warned that exchange rate headwinds will further increase, while the search business will also face high base pressure from accelerated growth in the third quarter of 2025.

### Cloud Business Shines, But Profits Are Devoured by AI R&D Black Hole

The only highlight in the financial report that exceeded expectations came from Google Cloud.

Cloud revenue doubled year-on-year to $30.7 billion, with the department's profit margin soaring from 23.7% to 36.2%, far exceeding the market's expectation of about 33%. Nearly 100 customers are using TPU. The backlog of cloud business orders reached $561 billion, a year-on-year increase of 256%, with the company stating that about 55% will convert to revenue in the next 24 months. Nearly 100 customers are using TPU.

However, the problem is that the strong growth in cloud business has not sufficiently translated into group profits.

The shared AI R&D losses at the Alphabet level expanded from $4.5 billion a year ago to $7.7 billion, with Other Bets losing another $2 billion. Rough estimates suggest that about half of the incremental profit from the cloud business was consumed before reaching the consolidated income statement.

Goldman Sachs analyst Eric Sheridan summarized this phenomenon in his quarterly report as "slowing search business, with ongoing needs for computing power investment." He pointed out that management continues to emphasize its leadership in cutting-edge models, including the releases of Genie 4 and Gemini C4 Carbon, while also acknowledging that available computing power remains a limiting factor for further acceleration of the cloud business.

This is also the market's core concern: strong demand for cloud business, with even stronger demand for AI capital expenditures. Growth seems to be present, but cash returns still need to wait.

### Free Cash Flow in Crisis, Buybacks at Zero, Turning to Debt and Stock Sales

The most shocking information from this financial report may not come from the income statement but from the disclosure of financing activities.

The market originally expected Alphabet to consume about $3.5 billion in free cash flow this quarter. The actual figure was nearly three times this expectation. Capital expenditures were $51.4 billion, below the market expectation of $55.8 billion, but operating cash flow fell 13% year-on-year to $42.3 billion, far below the market expectation of $53.9 billion. Capital expenditures doubled within a year, while operating cash flow regressed.


Even more noteworthy is the fundamental shift in financing structure. In the first three quarters of 2026, Alphabet's stock buyback amount was zero—compared to $39.8 billion in the same period of 2025. Meanwhile, the company raised $4.3 billion by selling 12 million Class A shares and $8.1 billion by selling 24 million Class C shares, totaling $12.4 billion in new stock issuance, with $27.6 billion remaining in the ATM plan. Additionally, the company issued $28.7 billion in preferred unsecured bonds, with quarterly interest expenses soaring from $143 million a year ago to $967 million.

In comparison, in the first three quarters of 2025, Alphabet returned $44.4 billion to investors through financing activities; while in the first three quarters of 2026, the company net financed $115.8 billion, including $42.9 billion in common stock (of which $10 billion came from Berkshire Hathaway), $19.1 billion in mandatory convertible preferred stock, and $76.3 billion in net new debt.

Management stated that they expect the return on investment to be "significantly higher than the cost of capital." However, the cost of capital itself has been rising: Alphabet's average selling price for shares was about $358 for Class A and $338 for Class C, while the pre-market stock price was about $290, meaning the company completed financing at prices 15% to 20% higher than the current market price—this may be the most profitable transaction it made this quarter.

### Market Narrative Shifts, AI Sector Faces New Test of "Proving Returns"

The market impact of this financial report has extended beyond Alphabet itself, directly addressing the core of the entire AI investment logic.

Goldman Sachs trader Thales Arruda noted in his morning report that the market is experiencing a shift from "rewarding capital expenditure growth" to "demanding evidence of returns," describing the current "pain trade" as large-scale cloud vendors underperforming the market, while de-risked "shovel and pickaxe" type stocks begin to gain traction. He also pointed out that improvements in credit market stability and Oracle's financial report may be more decisive for high-leverage infrastructure complexes than any single large-scale cloud vendor's report.

JPMorgan's market intelligence team characterized this financial report as "a setback for reigniting AI/tech trades," noting that pre-market price trends indicate the continuation of a broad rotation trend. The bank cited a precedent from earlier this year: between January and February 20, the energy sector rose by 22%, materials by 16%, and industrials by 14%, while the tech sector fell by 3.5%, with the S&P 500's overall increase being less than 1%. JPMorgan maintains a "tactically bullish" stance, believing that the main risk comes from escalating geopolitical conflicts in the Middle East rather than the financial report itself, and stated they will buy on dips.

Regarding analyst target prices, several institutions have lowered their target prices while maintaining ratings: Bernstein cut its target from $385 to $325, Bank of America from $430 to $380, JPMorgan from $425 to $375, Morgan Stanley from $400 to $375, Barclays from $425 to $405, and Susquehanna from $460 to $400. Citizens is the only institution to downgrade its rating to "market perform." Even after the downgrades, the median analyst target price remains about 30% higher than the pre-market price.

Bank of America pointed out that at about $291, Alphabet's stock corresponds to a price-to-earnings ratio of about 19 times for 2027 and about 16 times for 2028, with the core search business valuation at only about 10 times. This may be a buy signal, provided the market believes the earnings forecast for 2028 is credible and that no other competitors will preemptively seize this market share. Just as Alphabet struggles with monetization challenges, Microsoft Azure has exceeded expectations in growth, guiding fixed exchange rate growth of 49% to 50% for the next quarter. This comparison makes the logic of differentiation among winners in AI infrastructure investment increasingly clear.
