#美股财报季 #每周来晒 Five Tech Giants Compared: Who Looks Most Promising? The Answer May Surprise You

Tesla and Meta have reported; Microsoft, Alphabet, Amazon, Apple, and Nvidia each have their own concerns.
First, where I stand: I’m most bullish on Microsoft. Not because it’s growing the fastest, but because it’s the only company that has clearly explained the “spend money → make money” cycle.

Microsoft: A “textbook case” for AI investment returns. Azure growth is 43% (the fastest since 2022), with next-quarter guidance set at 45%—growth is still accelerating, not slowing. Cloud backlog is $678 billion (+84%), paid Copilot seats have topped 30 million, and GitHub Copilot has 50 million users. Most importantly, after spending $41 billion on capital expenditures, free cash flow was still positive at $19.6 billion. The stock surged 15% in a single day after earnings, adding $450 billion in market cap in one day—the largest single-day gain in history. The market voted with real money: its capex is actually turning into revenue.

Nvidia: The fastest growth, but investors need to accept two new variables. Revenue was $96.2 billion (+106%), with data center revenue at $89 billion (+117%). Guidance calls for $108 billion in Q3 and another 70% growth in FY28—the numbers are impeccable. But rising memory prices are starting to eat into gross margins (expected to bottom at 71-72% in Q4), and supply will remain a bottleneck through the end of 2028. The “picks and shovels” seller’s problem has shifted from “no one’s buying” to “we can’t make enough.” It has the most upside—and the most volatility.

Alphabet: Cloud growth is explosive, yet the market voted with its feet. Google Cloud grew 82%, with a 35.6% profit margin—impressive, right? Yet the stock fell 7% after earnings. That’s because capex was raised again to $200 billion and free cash flow turned negative for the first time. The market is asking: when will you earn it back?

Amazon: Steady, but look closely at the numbers. AWS grew 37% (the fastest in 18 quarters), with $220 billion in capex piled on top. Looks fine. But $53.4 billion of its $62.6 billion net income came from unrealized gains on Anthropic, and TTM free cash flow is negative.

Apple: The safest, but with the thinnest AI story. Revenue last quarter hit a record $109.4 billion (+16%), with iPhone up 22%. But AI hasn’t become a revenue stream yet—Siri AI just launched, and the company charges for iCloud+. Next-quarter guidance also fell to 9-11% (due to supply chain constraints). It’s a “value stock in the AI era,” not a growth stock.

So
Who looks most promising? Microsoft. The benchmark isn’t growth rate, but “visibility into capex conversion”—Azure is accelerating from 43% to 45%, and RPO is $678 billion. That’s the answer.
Can AI investment drive sustained growth? Yes, but with a condition: there must be evidence of revenue (cloud growth, subscriptions, backlog). Nvidia says it can still grow 70% in FY28, which shows demand isn’t the problem; but data center capacity could be in excess by 2028, and then the test will be utilization, not capacity.
Does beating expectations always mean a stock will rise? This earnings season has the answer: Microsoft beat expectations and accelerated its guidance → surged; Alphabet beat expectations but raised capex again → fell 7%; Tesla beat expectations but cut capex → reversed lower; Meta’s cash flow turned negative but it showed evidence of Muse monetization → rose 6%. The market never prices in whether a company “beat expectations”; it prices in the gap versus expectations, the direction of guidance, and evidence of ROI.

In a word: this earnings season, the winners are the companies that turn AI spending into visible revenue.
