交易者也在观察风险传导效果。这四档公司自3月低点以来约贡献超过60% 指数上涨，期权资料显示至少有$750 billion（约0.75兆美元）的资金曝险与其相关。若结果同时支持未来营收、盈利及上修指引，AI 投资支出可能被市场接纳；若指引出现下修，波动将快速放大并对 S&P 500 形成明显压力。
单体预期仍差异分明。Microsoft 今年下跌约13%，曾因 Azure 收入增长不及预期单日下挫10%，并蒸发约$357 billion（0.357兆美元）市值；但其Q3预估 Azure 收入仍成长38%，且 FY2027 资本支出预估约$176 billion（0.176兆美元，含租赁）。Alphabet 预计Q1净利约$32 billion，较去年减8%，营收约$92 billion，年增20%，Google Cloud 估计增至$18.4 billion 年增50%。Meta 年净利预估$17.2 billion、营收$56 billion，较去年增3.4%与31%，但自由现金流仅$3.9 billion（近四年低点）且拟裁减约10%员工。Amazon 预估Q1净利$18 billion、营收$177 billion，增幅5%与14%，AWS销售增速预估26%，高于Q4的24%，而本月股价已上涨超过25%。
On Wednesday after the bell, Alphabet, Amazon, Meta, and Microsoft are set to report earnings almost simultaneously — within about 80 seconds. As part of the Magnificent Seven with Nvidia, Apple, and Tesla, they have helped the S&P 500 set repeated record closes and push it toward its best monthly pace since July 2022. Traders are now emphasizing AI-driven spending efficiency and revenue trends rather than purely core-business metrics. The four firms alone represent more than 15% of the S&P 500’s total market capitalization, so guidance shifts can materially influence the index’s next direction.
Financial markets are also watching the wider transmission channel: these companies were behind more than 60% of the S&P 500’s gain from the March bottom. Option positioning linked to them implies more than US$750 billion (US$0.75 trillion) of at-risk exposure. If AI capex is matched by stronger measured revenue and upward guidance, stocks can absorb the outlays; if guidance slips, index volatility and downside pressure are expected to rise quickly.
Company-level expectations remain mixed. Microsoft is down about 13% this year and previously experienced a severe reaction when weak Azure growth triggered a 10% drop that erased about US$357 billion (0.357 trillion) in market value; its fiscal Q3 still expects Azure revenue growth of 38%, while FY2027 capex is seen near US$176 billion (US$0.176 trillion, including leases). Alphabet is expected to post about US$32 billion net income in Q1, down 8%, with revenue near US$92 billion, up 20%, and Google Cloud up 50% to US$18.4 billion. Meta’s AI-led strategy is expected to generate US$17.2 billion net income on US$56 billion revenue, up 3.4% and 31%, while free cash flow is only US$3.9 billion and the firm plans roughly 10% workforce cuts. Amazon is forecast to earn US$18 billion on US$177 billion revenue, up 5% and 14%, with AWS growth rising to 26% from 24% in Q4, even as shares rose more than 25% in April.
