Apple fell 8 percent and Amazon rose 9 percent on the same night. Apple and Amazon reported after market close yesterday and moved in opposite directions, setting the tone for this earnings season. Apple beat expectations but dropped as much as 8 percent in after-hours trading. Amazon also beat expectations and rose 8 to 9 percent. Neither result was poor—only one came with guidance that pleased the market. Apple’s quarter was strong across nearly all metrics: revenue up 16% to $109.4 billion, net income up 27% to $29.8 billion, supported by tariff refunds following the Supreme Court’s February ruling overturning Trump-era tariffs. iPhone revenue rose 22% to $54.3 billion; Mac revenue rose 29%. Services grew 12% to $30.7 billion—a slight miss, and ironically, the very line analysts had hoped would be perfect. The damage came from guidance. Management forecast 9 to 11% revenue growth for the September quarter, below consensus. Tim Cook attributed the upper limit not to weak demand but to unexpectedly strong demand—a good problem, but poor messaging for a market that prices in supply risk. The specific concern is memory costs. Apple already raised prices for Mac and iPad in June. Memory contract prices rose roughly 95% quarter-over-quarter earlier this year, and Samsung said yesterday at its own conference that the shortage will intensify through 2027 and into 2028. This same shortage, which generated a 52% operating margin for Samsung, has become a gross margin issue for Apple. That’s the entire memory story in one sentence: someone must absorb the input cost increases—and it’s the device manufacturers. Apple has the industry’s best supply chain and deepest pockets for pre-purchasing, yet even so, its guidance couldn’t exceed 11%. Amazon didn’t face this problem. AWS grew 37%, net revenue rose 20%, and advertising hit a record. Accelerated cloud growth at this scale is the cleanest possible answer to the question the market has asked all week: have AI investments started translating into revenue? Microsoft answered it Wednesday with Azure at 43% growth and rose 7%. Meta couldn’t and fell. Amazon could—and rose. It was also Cook’s final quarter. John Ternus takes over as CEO on September 1; Cook transitions to Executive Chairman, closing out fifteen years. He hands over a company that just delivered 16% revenue growth—and still got sold off, because its guidance implied demand was too strong. Read the article: https://t.co/fHxGxUp1hY
