Stock Movers: Apple, Amazon, Reddit (Podcast)

Apple's shares surged after reporting third-quarter revenue of $94 billion, significantly exceeding analyst estimates, driven by strong iPhone sales and a rebound in China. Conversely, Amazon's stock fell in after-hours trading as its current quarter operating income forecast, ranging from $15.5 billion to $20.5 billion, missed analyst expectations, raising investor concerns about heavy AI infrastructure spending despite robust sales guidance. Meanwhile, Reddit's shares jumped following its most profitable quarter to date and a strong third-quarter sales outlook of $535 million to $545 million, well above analyst estimates, signaling strength in its advertising business.

Analysis

The latest earnings reports reveal a significant divergence in performance and investor sentiment across the technology sector. Apple (AAPL) demonstrated considerable operational strength, with its shares surging after delivering third-quarter revenue of $94 billion, a 9.6% year-over-year increase that substantially surpassed the $89.3 billion consensus estimate. This outperformance was driven by robust iPhone sales and a notable resurgence in the Greater China market, effectively overcoming a projected $900 million tariff headwind. In contrast, Amazon (AMZN) shares declined despite a strong Q2 revenue beat, where sales grew 13% to $167.7 billion. The negative reaction was triggered by a disappointing operating income forecast for the current quarter ($15.5 billion to $20.5 billion), which fell short of the $19.4 billion analyst estimate at its midpoint. This signals that heavy capital expenditures in the AI infrastructure race against Microsoft and Alphabet are pressuring margins, a concern amplified by relatively modest growth in its key Amazon Web Services division, which grew 17% to $30.9 billion, just clearing the $30.8 billion estimate. Meanwhile, Reddit (RDDT) posted standout results, with its stock jumping on the back of its most profitable quarter and a highly optimistic third-quarter sales projection of $535 million to $545 million, far exceeding the $473 million Wall Street expected, indicating successful monetization of its advertising platform.

Key Decisions for Investors

• Investors may view Apple's strong revenue beat and resilience in China as confirmation of its premium market position, warranting a continued bullish stance while monitoring for signs that the tariff-related sales boost was a one-off event.
• For Amazon, the focus shifts to the trade-off between long-term AI positioning and near-term margin compression; investors should closely scrutinize future AWS growth rates relative to capital expenditures as a key performance indicator.
• Reddit's significant outperformance in both profit and forward guidance signals accelerating momentum in its advertising business, presenting a compelling case for growth-focused portfolios, albeit with the volatility typical of a newly public company.
