财报后，美国四大云厂市值蒸发1万亿美元，市场甚至寻求对冲“大厂风险”

Core Viewpoint - The recent earnings reports have led to a significant decline in the market capitalization of the four major cloud companies in the U.S., with a total loss exceeding $1 trillion, as investors express concerns over unsustainable AI infrastructure investments, cash flow pressures, and rising debt levels [1][8]. Group 1: Market Reactions - Microsoft shares have dropped 27% from recent highs, while Amazon, Meta, and Alphabet have seen declines of 21%, 16%, and 11% respectively, indicating a shift in market sentiment from "Is AI worth it?" to "Can capital expenditures be sustained?" [1][8]. - The capital expenditure of major cloud firms is projected to surge from approximately $485 billion between 2022-2024 to nearly $1.4 trillion from 2025-2027, raising concerns about potential overcapacity and elongated return cycles [8]. Group 2: Debt Market Dynamics - Concerns among debt investors are driving the rapid expansion of the credit derivatives market, with single-name credit default swaps (CDS) for companies like Meta and Alphabet becoming increasingly active [3][11]. - The CDS contracts for Alphabet and Meta are valued at approximately $895 million and $687 million respectively, reflecting heightened market activity [5][11]. - Morgan Stanley forecasts that the borrowing by major cloud firms will reach $400 billion this year, significantly higher than the $165 billion expected in 2025 [6]. Group 3: Financial Projections and Risks - Goldman Sachs anticipates that if capital expenditures reach $700 billion by 2026, it would nearly equal the total operating cash flow of major cloud firms, indicating a potential cash flow crisis [12][14]. - Only Microsoft is expected to have operating cash flow sufficient to cover its capital expenditures by 2026, while other firms may face a shift from "net debt neutral" to "net positive debt" [14]. - The issuance of bonds has reached record levels, with Oracle issuing $25 billion and Alphabet increasing its bond issuance from $15 billion to $20 billion, both attracting substantial investor interest [14]. Group 4: Market Divergence and Future Outlook - Despite strong current demand for bonds, there is a divergence in market sentiment, with some hedge funds viewing the demand for protection as a profit opportunity, while others warn of potential mispricing of credit risks [15]. - Goldman Sachs notes that to maintain investor return expectations, these companies would need to achieve annual profits exceeding $1 trillion, while current consensus estimates for 2026 profits stand at only $450 billion [15]. - The ultimate outcome will depend on whether AI investments can replicate the profitability trajectory of cloud computing, as seen with Amazon AWS achieving breakeven within three years and a 30% operating margin within ten years [16].
